This is the first pair of Saucony running shoes that I’ve tried. But I had heard good things about the brand before.
The Freedom ISO 2 is a neutral running shoe with a low drop of just 4 mm, with a forefoot height of 18 mm and a heel height of 22 mm. It only weighs 232 grams.
The Freedom ISO 2 is part of the ISO series, which are shoes that have Saucony’s ISO Fit. The ISO Fit wraps the shoe securely around the midfoot.
I normally use the extra eyelet to tie my shoelaces, but I found that when I did that with the Freedom ISO 2, it created too much pressure on top of my foot. So, I tried lacing them one eyelet lower.
Even then, I had some issues with finding the balance between the ISO Fit and the rest of the upper. If I locked down my foot, firmly the rest of the upper would fit better, but the ISO Fit system would create a bit too much pressure on my foot.
If I loosened the laces a bit, the fit of the upper would be less secure. I never quite got the hang of it.
Saucony has used ISO Fit before in other models, and I’ve heard it works a bit differently in every model. Some might work better for your foot than others. But the Freedom ISO 2 now also has an upper which is made out of the new ISO Knit.
The Freedom ISO 2 has a single layer knit upper, and that does make the upper quite breathable, but that will also mean you’ll easily get wet feet in wet weather conditions.
The shoe doesn’t have a full heel cup but a support frame, a supportive arch made out of quite flexible plastic, running along the top of the heel counter.
The midsole consists of Saucony’s Everun material. It is a soft cushion, but it is also responsive. You sink into the midsole a little while running, which is the kind of cushioning that I like.
Saucony has shoes that have the full Everun midsole and shoes that only have an Everun topsole, and the rest of the midsole is made out of EVA. The Freedom ISO 2 has the full Everun midsole.
I like that the insole of the shoe has a performance contoured footbed. It is not a very thick insole, but it does do the trick.
The outsole is made out of Crystal Rubber, which provides both traction and durability.
The traction of this shoe is indeed pretty good. The shoe does alright on easy trails, and I even managed to run in the snow with this shoe.
The Freedom ISO 2 is a low drop shoe. According to Saucony, this will result in you relying more on your natural gait and less on the cushioning and the stability of the shoe.
I clearly noticed it when I started running in this shoe. I really needed to foam roll after my first run in the Freedom ISO 2.
I’ve ran in the Skechers GoTrail Ultra 4 shoes before, which also have a 4 mm drop and are actually one of my favorite shoes, but I never had the feeling I needed to transition into those like I did with the Freedom ISO 2.
Both the Freedom ISO 2 and the Elevon are responsive shoes, but Saucony’s Everun in the Freedom ISO 2 has more of a springy feel to it than the Hoka Elevon. And the durability of the outsole of the Freedom ISO 2 is much better than that of the Elevon.
The support frame on the heel together with the knit, sock-like upper do not provide enough stability. Just because the shoe has a low drop doesn’t mean you don’t need any stability.
If I pinch the heel of this shoe, it can easily be pinched together. Something that I generally can’t do with the heels of other running shoes.
It is a responsive and cushioned ride, but it is not a maximalist shoe. It is more a springy everyday running shoe. It kind of reminds me of the Nike Pegasus Turbo in a way, but at the same time, it’s a very different shoe.
The Saucony Freedom ISO 2 is something in between a racing shoe and a long distance shoe. It’s more suited for those short to medium distance training runs where you still want some ground feel, but also a little bit of cushioning.
I ordered the shoes half a size up from my normal running shoe size, just to be on the safe side since I’ve never worn Saucony before. But it turns out that wasn’t necessary, and I could have just gone with my normal size.
I also noticed that the plastic overlays on the front of the shoe seemed to differ in size between the two shoes, as if one was meant to be for a size larger shoe than the other (on the left shoe the overlay is almost a centimeter longer than on the right shoe).
This could easily have been a manufacturing mistake. However, I could feel that the left shoe fit a bit differently than the right shoe.
I really like the Everun material for being soft yet responsive, although personally, I prefer a bit more of a maximal cushioning shoe. The Everun is maybe not as responsive as Nike’s ZoomX foam, but it is still pretty impressive.
I also like the traction the Crystal Rubber outsole gives you. But I’m a bit less impressed with the upper of the Freedom ISO 2.
It’s almost as if this shoe is actually two shoes in one; I really like the sole, but can’t come to terms with the unstable upper. I can’t really figure this shoe out.
I really want to like this shoe, because I like the midsole material, but at the same time, there are so many things wrong with the upper. It’s a bit too much freedom for me, not in terms of bulk, but because of the instability of the upper.
If you took the Adidas Solar Boost and made it more comfortable by removing the cage, adding in more plushness and a knitted material upper, the result would be the Freedom ISO 2.
The Everun midsole is denser and firmer than Boost, but the Freedom has an Everun sock liner for added step-in cushioning.
I ran in the Freedom ISO 1, and I can easily say that this version is an improvement in every aspect of the shoe. It overall feels more refined and elegant.
The Freedom ISO 2 is not a fast shoe. Thus, so I use it for my daily trainer needs. It is bottom-heavy due to the weight of the Everun midsole. I find it too heavy to use for 5km distances or less.
This shoe model has a luxurious upper. It is much better than the Freedom 1. The padding is thick, and the inside lining is smooth, which reminds me of Brooks’ uppers.
The laces are very long, so I use the heel lock method to make them shorter.
The heel is very padded, which feels “relaxed” but not loose. There is no heel slippage here. The tongue is also padded and does not slip around due to the sleeved interior.
In my opinion, it is the second most durable shoe rubber after Continental. The clear rubber is very dense and hard, taking away some of the shoe’s plushness.
On dry surfaces, the outsole grip is sufficient. But, in wet weather, it gets slippery, and you have to run carefully.
The pattern of the outsole provides a very smooth ride with not much ground feel due to the hardness of the crystal rubber.
I expect this outsole to last longer than most shoes and to be fine after 800+ kms.
If you took an Adidas Boost midsole and compressed it, you would get an Everun midsole. It feels like a faster midsole.
There are two notches on the medial forefoot. These are not found in the previous version of the shoe.
The medial forefoot is my favourite part of the shoe. It keeps your foot centered and gives you support on the medial side. It’s the first time I’ve ever seen this on a running shoe.
Usually, the cup support is at the back of the shoe, around the heel. These notches make the shoe feel more stable by stopping your forefoot from rolling inward.
Another big difference is that the midsole now flexes further forward than the Freedom 1. It used to flex slap bang in the middle of the shoe, which caused me some midfoot discomfort.
The Freedom 2 flexes further up the shoe, just before the two notches.
The ride is smooth, much smoother than an Adidas shoe. It is because the foam does not poke through the holes in the strobel lining underneath the insole.
I enjoy the plush step-in feel from the Everun insole, and I enjoy the lack of mushiness.
However, one does get the feeling that Saucony needs to update Everun sooner rather than later.
It cannot match the other super foams like Zoom X, Floatride Energy or Hyperburst because it is not as springy and not as light.
Overall, the Freedom ISO 2 is a very well rounded shoe. It has a comfortable upper, plenty of cushioning, plenty of responsiveness and a lot of stability.
I would take this shoe over any Adidas Boost. It has more comfortable upper and smoother ride. Adidas Solar is more lifestyle-oriented and not as performance-oriented as Freedom ISO 2.
Meanwhile, the faster shoes such as the Boston/Adios are nowhere near the cushioning level the Freedom 2 has.
I also miss the brightly coloured painted midsole of the original Freedom.
Saucony introduced their Freedom ISO in 2017. And, in late 2018, they launched the next iteration: the Freedom ISO 2.
It is loaded with techs like ISOKNIT and ISOFIT upper and full-length EVERUN midsole. I think Saucony is trying to make EVERUN like the Adidas boost foam.
So, did they succeed in it or failed?
- Full-length EVERUN midsole
- ISOKNIT upper
- Tri-Flex Crystal Rubber Outsole
- Pronation: None
- Cushion: Plush
- Construction Type: Neutral
- Surface: Road, track
- Arch: Normal, High
- Water Resistant:- No
- Offset: 4mm
- Heel: 22mm/18mm
- Fit: True to size
- Closure: Lace-up
Saucony Freedom ISO 2 features ISOKNIT and ISOFIT upper. The upper has a dual-tone pattern. The toe box is grey, and from midfoot, it looks like someone has sprayed green colour.
I like the colourways of the Saucony Freedom ISO 2. Now, let's jump onto the technical functionality of the shoe.
When I ordered this pair, I was excited as this was going to be my first pair of Saucony. When I unboxed the shoe, I was pretty impressed with its colourway and looks.
But, when I put them on, I did not find them as appealing as they look.
The Freedom ISO 2 features ISOFIT technology in their upper, which is aimed to provide custom-fit or sock-like fit. But, it did not provide a sock-like fit at all. I found the upper way too loose.
I don't know why Saucony called it ISOKNIT. The materials used in the upper feels like the traditional mesh. I found the upper to be very awkward.
It was not able to provide the snug and secure fit that one expects from the upper. Despite the use of ISOKNIT and ISOFIT technology, the upper did not fit well for me.
I found the upper to be very breathable, and the upper has laser-cut holes all over the toe box, which are too big that I was able to see my socks through them. I ran a few miles in them at around 100°F, and my feet were sweat-free.
Now, Freedom ISO 2 features a gusseted tongue, which provides a little bit of support and keeps the midfoot in place. The tongue is also nicely padded.
Toe box and lacing
Freedom ISO 2 has a wide-foot-friendly toe box. Runners with wide foot will find the toe box of Freedom ISO 2 to be heaven. The whole toe box is covered with a pattern of holes with a slight hint of green colour.
Saucony provided five lace loops. On one lateral side of the lace loop, "ISO" is written with silver colour while "FIT" is on the other lateral side to indicate that it has ISOFIT upper.
I have found the lacing system of Freedom ISO 2 to be the most complicated lacing system I have ever seen on a shoe. It was challenging to adjust the laces and tie them tightly.
Heel and heel counter
Freedom ISO 2 does not have an internal or external heel cup. It just has a simple moulded strip of plastic. This moulded strip of plastic does not provide proper heel lockdown and neither provide lateral support.
When I was running on uneven surfaces, I rolled my heel around three times within 5km. This plastic strip only worked when running in a straight direction. And, when I started changing directions, I have to face the stability issue.
Freedom ISO 2 has a full-length EVERUN midsole. Saucony has tried to mimic the boost, which looks almost the same as boost only that boost has bigger pellets.
However, Saucony failed badly, and I found EVERUN midsole not even close to boost. It is less responsive and not as plush or soft.
When I took out the insole, I found Saucony has only provided a thin layer of EVERUN, and beneath it, it's just traditional EVA foam.
I even don't know why Saucony tagged it as a plush shoe. I could feel plushness of the shoe only in the heel and tongue. But, the midsole felt very firm, and it was not plush at all.
The EVERUN midsole is not as responsive as compared to its competitors like Zoom X, Boost or Brooks's DNA AMP.
Freedom Iso 2 uses FORMFIT cushioning, which aims to provide contoured cushioning. But, I think it's just for marketing as I did not find any difference in cushioning from heel to toe.
When I took these shoe for a long-distance run, the midsole was not very responsive. Nevertheless, it provided good impact protection.
Saucony Freedom ISO 2 features a crystal rubber outsole, which is green in colour (may vary according to the colour away). It has "EVERUN" printed under the crystal rubber, which I think looks pretty cool.
Saucony has provided tri-flex grooves in the outsole for flexibility. The durability of the outsole is outstanding. There was not even the slightest sign of wear and tear after using them for 20 miles.
Traction is also perfect. Most road running shoes are not able to hold well on wet grasses and wet surfaces. However, this shoe is an exception, and all the credit goes to the crystal rubber outsole.
The only thing that lacks in this shoe is support. The support in this shoe is almost negligible despite using elements like moulded plastic strip, engineered knit upper, and ISOFIT.
The upper and midsole are also very flexible. When I ran on linear surfaces, it was fine. But, when I started running on uneven surfaces, it leads to ankle rolling.
As the shoe also lacks lateral support and way too loose upper, it caused sliding of the foot while taking sharp turns.
Despite placing the moulded plastic strip at the heel, it did not prevent the heel from rolling and did not lock the heel properly.
Ride and performance
The shoe provides a fairly responsive ride, but not as responsive as compared to its competitors around the same price range. Saucony mentioned the ride of the shoe to be soft and plush. But, on the contrary, it was firm.
Runners who like to run in React, Zoom X, or any other cushioning technology will find EVERUN to be way behind them in terms of responsiveness and plush feel.
I found the performance of this EVERUN midsole not as appealing as one expects from $160 shoe. Saucony has mentioned that they have made ISOKNIT upper for added support and a sock-like fit.
But, whenever I used this shoe, I was not able to get the support and sock-like fit from the ISOKNIT upper. This shoe will be last on my list for running.
Saucony Freedom ISO 2 fits true to size. But, I should have gone half a size down because of the wide toe box. I suggest trying this shoe before ordering because everyone's feet is different.
Freedom ISO 2 has ISOFIT upper, which does not provide a snug and secure fit. Saucony also introduced ISOKNIT in Freedom ISO 2 for a sock-like fit and added support and stability.
But still, the upper felt too roomy for me. Even after adjusting the lacing multiple times, I failed to get the desired fit. Also, I still had issues like ankle rolling and sliding of the foot while taking sharp turns.
As mentioned, I found the lacing system to be too complicated as it was tough to adjust the laces.
Traction is amazing due to the crystal rubber outsole. The crystal rubber gripped well on wet road and grass.
This outsole can handle light trail as well. However, due to the many tiny holes in upper for breathability, it will let in all dirt and water into the shoe.
I found the built quality of the shoe satisfactory. I have used them for 50miles and no sign of wear and tear on the outsole and no sign of fraying on upper. This shoe can give more than 400 miles easily.
- Breathable upper
- Wide forefoot
- Adequately padded heel and tongue
- Reflective elements at heel and midfoot
- Very flexible
- Not very plush as advertised
- Very wide forefoot
- Complicated lacing system
Saucony Freedom ISO 2 might be a good daily trainer for runners with wide feet or runners who like to have some extra room in their shoe. But, I found these too roomy according to my taste.
EVERUN midsole was not much responsive and upper lacked support. ISOFIT upper did not provide enough support around midfoot, and plastic heel strip did not lock the heel properly.
Some runners may love this shoe, but the choice of running shoes varies from person to person, and I did not like this shoe much. I hope Saucony will improve the fit of the upper in upcoming models of Freedom ISO 2.
The price tag of $160 is too much given the performance of the shoe. I don't find this shoe worth buying at a premium price point of $160 since Freedom ISO 2 offers way too less.
This review is an update to my previous review of these shoes, which was submitted in April 2019.
I’ll reiterate from my previous review that I have been running in Saucony’s for over a decade, specifically the excellent Kinvara model, which I’ve run in the 5, 6, and 7 model versions over the last 4 years.
Durability was one of my main concerns with these shoes. These are daily running shoes, so durability and value are extremely important considerations. Unfortunately, I have been let down by these shoes as I’ve taken them beyond 200 miles.
They do just about everything else right for a lightweight, comfortable, neutral shoe that I happily laced up for my 20+ mile long runs.
However, the classic “Saucony Toe Hole” issue started to manifest in these shoes around 175 miles, and I only wear these shoes for running.
Saucony, you know this is an issue. The three iterations of the Saucony Kinvara I’ve worn have also all developed the same toe holes. No other brand I wear gets holes in the upper like this--just Saucony--which is a shame because their shoes were such a joy to run in.
That said, I have never found the Saucony Toe Hole to be a hindrance to the performance of the shoe. It’s just frustrating to see the visible damage to the upper every time I glance down at my feet.
The classic “Saucony Toe Hole” in my right shoe.
The tread is holding up well.
As I mentioned above, the toe hole is frustrating, but it ultimately doesn’t affect the performance of the shoes.
However, after just 215 miles on these shoes, they started to feel a tad flat. It was like the midsole material was no longer cushioning as it should.
This was especially noticeable when I run downhill, as it feels like there’s almost nothing there to cushion my foot, and it feels worse every time I take them out.
I might run in these shoes a few more times, but they will be retired before they hit 300 miles and exclusively used for shorter runs till then.
I had initially hoped to get 500+ miles out of these shoes, as I was reliably able to get more than 450 from every pair of Kinvaras I used. If it was just the toe hole, I would have still been fine with the shoe, but the midsole is failing as well.
Another view of the shoes after 236 miles.
I thoroughly enjoyed running in these shoes, and they were a welcome addition to my running shoe rotation.
They did almost everything well, but they started to feel flat and develop the Saucony toe-hole after about 200 miles. These shoes will be retired before 300 miles, and I will no longer use them for long runs.
The Freedom ISO 2’s are $50 more than the new Kinvara 10’s, which I have not run in, but are well-reviewed and I have no doubt are excellent.
Durability and value are extremely important to me in a daily running shoe. This is especially since I run 3+ marathons a year and go through at least as many pairs of shoes per year.
With that kind of mileage, going through expensive shoes this quickly gets pricey. Three hundred miles from a $160 pair of daily running shoes is unacceptable.
If they were fast racing shoes, then that would be a different story, but they are not. There are as-good or better daily running shoes out there for less money.
If you want a Saucony shoe that is like the Freedom ISO 2, save your money, and buy the Kinvara 10.
- Fairly fast
- Definitely a great daily runner, but I don’t think I’ll race any marathons in these shoes
- However, I would definitely consider pacing a marathon in these shoes
- Sturdy but not too supportive
- Footbox is appropriately sized for comfort, but not too big to allow foot to move around too much
- Lots of traction from outsole
- The slightly stretchy, flat laces are almost perfect -- just a tad long
- I like other shoes just as much that are almost half the price
- Not good value considering the usage I got out of them
- Just a tad stiff
- Not durable
- Uppers developed “Saucony Toe Hole” at 175 miles
- Midsole cushioning started to feel flat after 215 miles.
I tried on the first Saucony Freedom ISO model in 2016 and didn’t quite love the feel or price enough to get them over the Saucony Kinvara 7 which I wound up purchasing.
Fast forward to March of 2019, when I received a coupon for a free pair of shoes of my choice for pacing a half-marathon.
I run in neutral, low heel-toe drop shoes, and decided to try on the Saucony Freedom ISO 2 in the store since it was one of the few shoes they had that I have not used and fit my running profile.
Brand new Saucony Freedom ISO 2
This second iteration of the Freedom ISO did not feel as weird as I remember the first model feeling, and after 4 minutes of running on the treadmill to test them out, I was happy with my choice. As of writing this review (April 2019), I’ve put 75 running miles on the shoes.
Like all Saucony shoes, these shoes are well built and look pretty good. When you pick them up, you’ll immediately notice how sturdy they feel.
They almost feel a tad on the heavy side, but that might also be because I’ve recently been running in the featherweight Altra Escalante and Brooks Pureflow 7, at 8.2 and 8.9 oz, respectively. But for how much should you get from the Freedom ISO 2, they are surprisingly lightweight!
The EVERUN midsole is a fairly standard thickness (18mm) for moderate cushioning, neutral shoes, and it’s just like I remember from the last Saucony shoe I ran in (the Kinvara 8). The midsole is springy, responsive, and does a great job of keeping your feet happy while they’re pounding the pavement.
The outsole of this shoe is what strikes me as the standout feature. It’s made of Saucony’s “highly durable TRI-FLEX crystal rubber”, and I have to hand it to Saucony.
They made a rubber compound that feels extremely durable but is also flexible enough to not make the shoe feel rigid despite almost the entire bottom being covered with the outsole material.
Higher mileage will show if this stuff is the real deal or not, but one thing you notice right away is how much grip these shoes have. They could almost pass as trail runners, especially if the trail run has long sections of pavement or crushed limestone.
If I’m running to the park where I trail run (4 miles away on pavement and sidewalks), these are the shoes I’d choose to lace up.
EVERUN foam midsole with TRI-FLEX crystal rubber outsole
I like the laces a lot. They are flat, which I prefer, but they are slightly stretchy, which I didn’t expect to like so much. My only complaint is they are a tad long. Just a few inches off and they’d be perfect!
The heel cup is very sturdy, the mesh upper is breathable (though I worry about its durability), and I like that the tongue is sewn directly to the sole to give the shoe a sock-like feel.
The ISO design is the slits in the lacing anchors on the upper (I am fairly certain of this, but it’s hard to find anything definitive online as to what specifically makes the ISO design). Saucony claims that ISO allows the upper to “adopt the shape and motion of a foot”.
Showing the tongue sewn down to the base of the shoe to keep it centered and give shoe sock-like feel
It does make for a comfortable shoe, but I wouldn’t say it’s significantly more comfortable than most other shoes I’ve run in. My feet did feel a tad more secure without needing to really cinch down on the laces.
But you don’t really need a ton of foot security from road shoes, you just need something that is comfortable and keeps the sole against your foot. That said, I have not done serious trail running in these shoes, and that could be where the ISO feature really shines.
However, in these shoes, it seems a little overkill. Finally, I’m not sure if it is something worth adding, especially since it seems like Saucony is incorporating it into most of their new lineup. Just call the shoe the Freedom 2 and drop the ISO.
Slits in the upper lacing anchors comprising the ISO design
I talk about the fit a little bit in the above, section, but to summarize:
Saucony claims that the ISO design is a “revolutionary fit system that morphs to the foot for a custom feel.” These shoes do fit pretty well, but if the premium price is coming from the ISO system, then I think I’m fine with a typical, simple upper and tongue that I can get in a cheaper shoe.
These shoes are comfortable, but not significantly more comfortable than the Altra Escalante or Brooks Pureflow 7 I’ve recently used. The ISO system might be worthwhile on the trails, however, it seems excessive on a road shoe.
I wear a size 12 in most shoes, and these are true to fit.
- Most Adidas shoes - 12
- Saucony Kinvara 5,6, and 7 - 12.5
- Brooks Pureflow 6 and 7 - 12.5
- Altra Escalante - 12
- Saucony Freedom ISO 2 - 12
I try to retire my shoes based on feel and wear, not mileage. Typically, one can expect 400-500 miles out of a pair of road shoes, but that depends on many things, like weight, running style, speed, and conditions.
I’m 6’1”, 165 lbs, in a size 12 shoe, and average ~7:15 min miles; which I imagine produces an average amount of wear compared to other male runners. I got about 450 miles out of my Kinvara 6, 7, and 8, granted my dog didn’t chew through a pair.
I got about the same distance out of the Brooks Pureflow 6 and Altra Escalante. The Kinvara 10, which I’m assuming are excellent and will last for ~450 miles based on the other three other Kinvara models I’ve worn, retail for $110, whereas the Freedom ISO 2 retails for $160, a 45% increase in price!
Saucony Freedom ISO 2 at 75 miles of running
Am I going to get 650 miles out of the Freedom ISO 2? I'm doubting at first, but seeing how durable the outsole even on crushed limestone trails, it just might.
However, even if the outsole can last to 650, I have my doubts about the midsole, but I’m eager to be proven wrong. My Freedom ISO 2 has about 75 miles on them, and they still feel and look almost brand new aside from a little dirt.
Since I do enjoy running in them quite a lot, I would say that if they can last till 600 miles, then they would be worth the premium price to me. If I found them at a discount, then they would definitely be worth buying.
I thoroughly enjoy running in these shoes and they have been a welcome addition to my running shoe rotation.
They do almost everything well, but I’m not yet convinced that they are worth the premium price. However, if these shoes last beyond 600 miles, I’ll happily conclude that they are worth it!
Regardless, I’m hopeful and eager to see how Saucony incorporates the outsole material into future shoes.
- Definitely a great daily runner, but I don’t think I’ll race any marathons in these shoes
- However, I would definitely consider pacing a marathon in these shoes
- Sturdy but not too supportive
- Footbox is appropriately sized for comfort, but not too big to allow the foot to move around too much
- Lots of traction from outsole
- I like other shoes just as much that is almost half the price
- Just a tad stiff
Would I recommend this to a friend?
If they can find them at a discount, I definitely would recommend them.
I recently purchased Saucony Freedom ISO 2 (Black), my first Saucony shoes. I bought this online for a good deal ($90), the retail price is $199. Penning down this review, I have logged 175kms.
Size and fit
This is the first Saucony shoe for me after hearing a lot of good things from my running partners. I was looking to add to my running collection, came across the deal for this road shoe, and ordered without even trying it in a store. Fortunately, the shoe is true to size.
The cushioning provided by EVERUN midsole delivers great comfort. The EVERUN offers higher energy return which helps to avoid long term pain or comfort issues.
I haven’t used the previous version of Freedom or any Saucony. So, for me to try an ISOKNIT upper was new, and it provides more breathability and greater support.
The ISOFIT wraps my midfoot well, which gives a greater secure fit to help adapt to my movements during the run. I ran in cold temperatures. The shoes are decent in keeping your feet warm (but I am not sure if it will be my go-to shoes if it’s very cold).
The full EVERUN midsole provides greater responsiveness and gives a good spring-like feeling during the run without compromising the cushioning. EVERUN is made up of thousands of TPU beads, which provide the soft landing.
The outsole is made up of crystal rubber. The look of the outsole is entirely new and not seen in many shoes. The outsole had a good grip on the roads and soft surfaces.
I ran with these shoes in snow, trail, and road. And, it provided good grip in road and trail. Considering they are not intended for winter running, I was surprised it did hold up decently in snow.
Traction of the shoes is decent in wet road surfaces. The additional grooves in the outsole were mainly to help the grip on wet conditions, but I am not sure if I will prefer these shoes for running in wet conditions.
Since this is my first Saucony shoes, I am not sure about the durability. For this, I will say from a lot of my friends, Saucony makes durable and long-lasting shoes.
During the run
The crystal rubber outsole provides great grip and support for the shoe. The EVERUN midsole provides great energy return and cushioning. You will feel the difference during the run.
During the run, you will feel the responsiveness of the shoe. The outsole, with more grooves, gives flexibility. The midsole gives the spring-like feeling because of EVERUN. All in all, they combine to make a perfect responsive shoe.
Feel of the shoe
The shoe feels lightweight during the run. You will not experience any comfort issues nor any rubbing against the materials during the run. The sock-like ISO FIT keep your midfoot secured and comfortable.
Styling and color
Not all running shoes can be used as casual shoes. But, Freedom ISO-2 (some colors) are suitable to be used as casual shoes. The simple yet nice design can fit your casual taste.
As far as coloring, choices are there to cater to everyone. But, if you prefer less flashy colors, then you are restricted to 2-3 colors. My pick would be black, grey, olive shade and last teal black.
Most of us oversee this aspect of running shoe, which can result in injury if not attended immediately. I am one example of this. If you think drop (heel-to-toe) is irrelevant during a change of running shoes, then please do take precautions.
I was predominantly using higher drop (10mm) and more of a midfoot to forefoot striker during the run. I changed to 8mm, and within a month, I bought Freedom ISO 2, which was 4mm.
I used Freedom ISO 2 consistently for longer runs without providing a break-in period. If you change your shoes and the drop difference is greater than 4mm, please do short runs and let your feet get used to the low drop else, you will risk getting Plantar Fasciitis.
I sustain the injury and couldn’t do much for two weeks (I was quick to react and identified the root cause, so I was able to get rid of it as it was in the initial stage).
If you plan to buy Freedom ISO 2 (4mm) and you are currently using 10-12 mm drop, I suggest taking it slow or have another pair that has 6-8 mm drop and slowly transition to Freedom ISO 2.
Why buy Freedom ISO 2
- Responsive and lightweight
- ISOKNIT upper is very nice
- EVERUN midsole provide greater energy during the run
- Decent color schemes
Why I would skip Freedom ISO 2
- If you will run more on wet surfaces
- If you are on a tight budget, then look elsewhere (unless you find a good sale)
- If you are running on higher drop shoes or more heel striker.
Stay away from this shoe if you want to keep running at the same “boring” pace and you do not want to improve your timings. Stay away from this shoe if you do not want to run fast on that 5k race or even on that marathon.
In short, keep using your usual brand or your current shoes if you are not ready for your next step.
Why the Saucony Freedom ISO?
This is your shoe to go from a 5k to a marathon. They are lighter than the beer that you get on the finish line.
As you know, the word that all the time is used to describe this kind of shoes is “responsive”. Indeed, they are. Adding to that, there is a perfect balance between the cushioning and the responsive underfoot feel.
Fits like a glove
I have been running on these shoes for a while, some 4 pairs, and counting. Another phrase they are usually associated all the time is: “they fit like a glove.”
I am pretty sure that you are aware about the rule of buying running shoes a half size bigger than your actual size. But yes, on these shoes, that rule applies. You will thank me later, and you are welcome.
Not for fashion runners
If you want to buy the freedom shoes because of their strong colors, these are not your shoes. You want these shoes because you want to break all your PRs. You want a cushioning shoe but without all that weight.
If you like to read technical facts, the stack height of these shoes is 4mm, what does it mean to you? Shoes with lower stack heights tend to have a firmer and responsive underfoot feel, while higher stack height shoes tend to have a softer, more compliant feel.
For those geek runners:
Forefoot height: 15mm
Heel height: 19mm
For the latest model:
- Pronation: none

Saucony named the style of this awesome sole, Everun. It is a foam which delivers a lot of return and cushioning. There are plenty of similar options in the market from other brands but in my opinion, Saucony did it well.
One thing that I noticed, there are some models that feel different, like a complete or another different shoe. For example, I bought on 2017 the special edition for 4th of July, they look awesome but they feel a bit different than the blue citron or yellow/orange models.
It is light and a cushioning shoe. One size fits all. These shoes will cover from a 5k race to a marathon race. I haven't tried them beyond this mark. Well, now that I am thinking of it, my coach sometimes makes me run more than 26 miles a few weeks before the big day. (Chicago Road Runners baby!)
It is also close to the ground with protection. Yes, this sounds with no sense but it is true.
Price - the original price of these shoes is $160. Please note this is the price for the newest version because, as you may be aware, you can buy the previous models (which is pretty much the same technology) on different colors.
You can search and get a good deal on the previous models on the usual spots, or also take a look at runrepeat.com. They keep updated content and where you can get the best deal.
Please keep a record on how many miles you run with these shoes. The thing is, they will keep looking awesome and in good shape after several miles.
But when they reach the threshold life (which for me is around 400-600 miles) you won't get the required the protection and the responsive feature so your runs will be quite harder.
Why this is listed as a con since this a normal behavior?
As mentioned, they will be looking in good shape and you will want to keep training on these shoes or even race with them, but your results or performance will not be the same. So please make sure you keep this in mind and record your miles.
- The Saucony Freedom ISO 2 is an update to a fresh series that’s meant to provide an accommodating performance to neutral pronators. It makes use of a form-fitting design to sanction the natural movement capacity of the wearer’s foot.
- ISOKNIT is the amalgamation of knitted textile and Saucony’s proprietary sock-like construction. It’s crafted to prevent skin irritation and hot spots while also bringing breathable support. A plastic support frame at the back of the shoe holds the heel and keeps it in place.
- The midsole unit of the Freedom ISO 2 uses a foam compound that’s made to absorb impact shock and provide responsive cushioning. It has a contoured midfoot to support and cushion the arch, as well. A flexible rubber acts as a shield against the abrasive nature of the surfaces.
The Saucony Freedom ISO 2 makes use of the standard measurements to deliver a true-to-size coverage. The women’s version has a width option of B – Medium while the one for men features the D – Medium variant. The semi-curved shape of this running shoe’s last accommodates the natural curvature of the human foot.
The outsole unit makes use of the TRI-FLEX crystal outsole, a durable material that’s meant to protect the rest of the platform from wear and tear. It has a transparent look to heighten the visuals of the external layer. Though it’s protective, it’s not firm or inflexible.
Gripping lugs allow the external layer to hold onto the ground with sureness and ease. They’re not too prominent to cause surface instability.
Horizontal and vertical grooves permit the platform to bend in conjunction with the inherent flexing capacity of the foot.
The underfoot platform of the Saucony Freedom ISO 2 makes use of the EVERUN. This foam unit offers responsive cushioning. It’s also designed to absorb impact during the landing phase of the gait cycle, then converting that energy to kinetic force that the leg can use to push off the ground. The EVERUN material is also added into the midsole of the Guide 10, Hurricane ISO 5, and other popular running shoes from Saucony.
ISOKNIT is a material that’s designed to resemble woven textile. It has a closed construction in the vital areas, but the front and sides open up to accommodate airflow. It doesn’t have a substantial weight, and it obliges the natural flexibility of the wearer’s foot.
The ISOFIT dynamic fit system allows the upper to hug the foot precisely, giving a well-fastened yet unrestrictive wrap.
A support frame is placed on the back portion. It’s a band made of synthetic material. Its purpose is to keep the heel in place and prevent it from wobbling or exiting the foot-chamber involuntarily.
The padded collar and tongue provide cushioning to the upper parts of the foot. Moreover, they prevent in-shoe quavering.
