Overview of this review
I am a 41-year-old runner, about 170 pounds and 6’ 1” tall. I race all distances, from 5ks to Marathons, and spend at least half of my year training for an upcoming marathon.
I’ve run in Newtons before. A few years ago I was frustrated at my lack of progress and bad form on my foot strike.
After a consultation with a shoe expert, I was fitted for a pair of Newton Kismet. It was a shocking transition from a plush stability shoe to a lightweight neutral shoe that forced me to land mid- to fore-foot.
I received some minor calf strains as I became used to the lugs underfoot, but 1,000 miles through 2 pairs of Newtons was the answer to correct my running form. I mention this to explain my high expectations of the Newton Gravity 7.
The Newton Gravity 7 is very lightweight and fit moderately well to my foot.
I was excited to see some modifications and improvements in the shoes compared to the last models I ran in a few years ago. Generally, the shoe felt fast, providing exceptional response underfoot.
I usually wear a size 12, so that’s what I ordered, and they fit snug. Every so often, I catch the toes on my right foot crashing into the end of the shoe, but it is not problematic.
Compared to the pair of Newtons I trained in a few years ago, the toe box for the Gravity 7 is quite spacious. My feet are not cramped, and my toes are able to splay naturally.
The heel is firm and fits closely to my foot. The drop of 3 millimeters makes for a very responsive heel.
When it comes to the arch, however, I noted that the support for my foot is somewhat lacking. People with higher arches may not find this shoe to be as supportive as needed.
I am very impressed with the upper portion of this shoe. The tongue is almost unnoticeable and the mesh is breathable but firm.
The midsole is moderately cushioned but very responsive.
The website claims a “biomechanical metatarsal sensor plate,” which I assume sits just above the lugs on the outsole. This combination makes for a very responsive shoe, allowing the runner to feel the road and adapt the feet through the stride.
The Gravity 7 is fitted with “Point Of Power” – POP1 – technology, which provides heavy rubber lugs under the forefoot. These lugs accomplish at least two things:
- They compel the runner to land mid- to fore-foot, which is probably the most efficient foot-strike.
- They give the runner a great sense of responsiveness on the go.
I jumped into the Gravity 7 with not much of an adaptation period. In fact, my first run in these was a warm up and 5k race. As a daily trainer, I have no complaints at all about the shoe’s function.
As noted above, I enjoy great responsiveness in the shoes, though I have NOT experienced a noticeable “POP” or additional springiness from the POP1 technology. My form and foot strike has become more efficient from running in these shoes, however.
Work out Adaptability
I ran in the Gravity 7 for 4 weeks, putting 226 miles on them, which is an average of 56 miles per week. I used these for speed work, long runs, recovery runs, and hill workouts.
I rank the workouts for which this shoe is best used below:
- Speed Workouts
- Long Runs
- Recovery Runs
- Hill Workouts
Let me explain why Hill Workouts ranked last: The POP1 technology made running UPHILL terrific! But they made running downhill uneven and problematic for me.
I was able to get 500 miles out of my last Newtons a few years ago. I am not as optimistic with this pair of Gravity 7. After 225 miles, the lugs look like they will only last another 100 miles or so. The foam portion of the heel is deteriorating pretty quickly.
This photo reveals how much the shoe can tear up if you allow a lazy foot strike. I estimate these shoes will probably only last around 300-350 miles before needing replacement.
- POP1 encourages proper foot strike.
- Lightweight = great trainer and racer.
- Midsole cushioning is adequate.
- Outsole foam on heel area deteriorates quickly.
- $175 is a little too much for a shorter life expectancy.
I am a big fan of Gravity 7. This shoe fits well, is exceptionally lightweight, and helps promote an efficient foot strike.
I am not pleased with the durability of the shoe, or its function on extreme downhill slopes. Otherwise, I find this shoe to be a very efficient daily trainer.
Check out my video review here.
I was given the privilege to test out the New Gravity 7 running shoes. I had been a longtime admirer of Newton shoes but had been afraid to try them because of the different style of running and the cost.
It was probably the cost that scared me the most because who wants to spend nearly $200 to find out that Newton shoes were impossible for them to adjust to. With the chance to try the shoes and give my opinion all at the cost of my review was very exciting.
These shoes are bright red and green (my kids refer to them as my Christmas shoes); I like how bright they are and I normally don’t like bright shoes.
The weight of the shoe seems near featherlike, I have been running on the trails in trail shoes for a long time but even for road shoes, they seem light. Newton puts a large 5 lug P.O.P platform at the back of the forefoot.
The P.O.P. system is designed to give momentum and provide the cushion. The midfoot of the outer sole looks like it is made of soft foam and as though it won’t hold up to the miles I hope to put on the shoe.
When I put the shoes on, I’m immediately impressed with its true to size fit. The upper is very soft and feels like it will breathe easily. The support fits my medium arched foot with near tailor like precision.
The tongue is comfortable and is sewn to elastic ties on both sides about half way down the tongue. Walking around the house provides a large wobbly rocking motion as I roll over the P.O.P. platform. I can’t wait to go for a run in these.
First run impression
I was expecting that I would have some pain or that I would have to run with a forefoot strike versus my more natural heel strike.
I was pleasantly surprised when I was able to easily convert to forefoot strike without any pain. I only ran 4 miles for my first run and the shoe felt light and fast.
The long haul
From day one on these shoes, it felt fast and I, for the first time in a long time, looked forward to speed work. This shoe will make you feel like you aren’t wearing shoes at all, giving that wonderful flying feeling.
I ran a few 5K races pacing one of my kids (19min/9-year-old) and while I wasn’t running hard it was nice to have these shoes on and I feel that they would make a good race day shoe. The shoe is fast and gives more cushion than you would expect from a shoe this light and thin.
On longer runs, the shoe still performs. I ran a hand full of 20 mile runs in them and while my feet felt a bit bruised up and my calves slightly more tired, they performed as good or better than my Adidas Boston Boost. Overall these shoes flat out perform.
The shoe construction is of higher quality than most shoes on the market. I did, however, experience issues with the outer sole separating from the midsole.
For the selling price of these shoes, I would have been upset with this material issue, however, it didn’t affect the overall performance of the shoe. This was the only material break down that the shoe suffered in over 300 hard miles of running.
Overall, the shoe performs like a sports car, it’s fast lightweight and responsive. It excels on the track and when performance is needed. Also, they can carry you through the long runs as well as much heavier training shoes.
If you have never used a forefoot striking shoe with a very small heel drop, it may take a couple weeks to get used to it. Once you get over the hump of sore calves you will really enjoy this shoe.
This shoe isn’t meant to be everyday wear around the house type of shoe, I’m not saying you can’t do it but I don’t think it would be comfortable. I don’t wear my running shoes for any purpose outside of running in but don’t think that this shoe would be fun to wear around outside of running.
This isn’t a cheap shoe which might keep and has kept me, from purchasing. At a suggested retail price of $175 for a shoe that will take a few weeks to get used to running in might not be for everyone. I would still recommend this shoe as it’s a fun shoe to run in plus everyone will look at you like you know what you are doing.
neutral running shoe that weighs 8.7 ounces and has a heel to toe drop of 3.0mm.
This is a barefoot-like shoe that promotes landing on the forefoot. This shoe is a beast and is able to be used for races or training.
Action-Reaction – With the use of the front lugs that move into the shoe when you land on it and gives you a pop of feeling when the lugs move out. It’s supposed to create a responsive feeling or “energy return”. It’s also supposed to add to the cushioning system.
Level Platform – A lower heel to toe drop to make you run on your forefoot more, which is a more natural way to run.
P.O.P 1 – Front lugs in the front of the shoe to provide a responsive feel and give better performance. The P.O.P 1s is a more aggressive type of lugs than the P.O.P 2s. The P.O.P 2s are like entry level lugs.
SHARC outsole – I’m not sure what this is but I’m assuming it provides a more durable outsole.
Biomechanical metatarsal sensor plate – A way to help you better feel the surface which provides a barefoot running experience.
Newtonium – Newton’s own foam cushioning that like all shoe companies claim it provides a responsive ride. In this particular shoe, the Newtonium foam is positioned closer to the foot. The shoe also has an additional EVA layer.
I’m not going to lie, the Gravity 7 is not really the most attractive shoe. It doesn’t have that sleek look that Nikes have but it's not the ugliest shoes in the world though. They do garner a lot of attention and only because it has a bright red upper that also happens to be reflective.
For a week, I was known as the red shoe kid. It would be nice if Newton provided other colorways but I didn’t mind the look since I would be running in them, not staring at them.
Newton has a sizing chart on their website that shows what size you should get based on your old shoes. I had Nikes and the chart said to order a half size up. I would recommend using that chart because my shoes fit perfectly.
The shoe fits nice and snug which made it feel stable while running. Cushioning on this shoe was awesome, it was responsive and comfortable. It was good for long runs when my feet got tired and hard repetitions on the track.
The heel counter kept my heel in place. Normally in shoes, I need to use a runner’s knot but on the Gravity, I didn’t need it.
The tongue also added to the comfort, the rest of the mesh upper was breathable and stretchy. It gave way for stretching but still kept my foot in place.
However, if you aren’t used to barefoot running, the lugs might feel uncomfortable for the first week or so. I normally try to run on my forefoot but the Newtons are completely different. My calves were hurting for the first week and even had spazzed out a couple of times. Running on my forefoot more and the lugs made my forefoot sore.
The lugs for the first week also felt uncomfortable for my feet. It felt like trying to use track spikes on concrete, it’s just wrong. After a week though I got used to it and now the lugs don’t bother me anymore. But the lugs still feel awkward when I’m walking or standing in the shoes.
I’ve used the shoes on the road, grass, trail, and track. Most of my running is on the road and track yet the outsole of the shoe is already showing damage. The forefoot and the edge of the shoe are padded and those parts aren’t showing any signs of except for being dirty.
The part of the outsole that isn’t padded, however, is showing signs of light abrasion. During the track season, I average about 20-30 miles so if you’re doing higher mileage than me I’m not sure how long the unpadded outsole is going to last. The rest of the shoe like the upper is fine, there’s no ripping or anything.
I have been using the Gravity 7 for my track season training, this includes long runs, tempo runs, and track repeats. Throughout all that, the shoe was able to help me push forward. Thanks to the shoe not weighing a lot it, was great, sometimes it felt like the shoe wasn’t there.
The responsiveness from the lugs made me want to run faster; it felt like the zoom air units in Nike Pegasus. It was hard to run slow in these shoes. Usually running on my forefoot doesn’t make a really big difference, but running on my forefoot in these shoes really propelled me forward.
I just didn’t like it when I had to run slow because I would then have to run on my heels. This causes my feet to roll all the way forward and I would feel the uncomfortable lugs.
I would say these shoes are good for racing or just training as long as it’s on solid surfaces. The shoe is fine for trails and grass but you won’t get the same responsiveness.
The only major flaw with the shoe is that when the surface you’re running on is wet, you’re guaranteed to slip. I was trying to do repeat 400 meters on a wet track and the entire time my feet were slipping around.
There just isn’t enough traction when the ground wet. I never had a problem with other shoes when the ground is wet, but there’s something with these shoes that makes it not able to handle wet surfaces.
- Makes you feel and run fast
- Fits true to size and fits snug
- Breathable and stable mesh upper
- Reflective (useful for night running)
- Light weight (only 8.7 ounces)
- Not the most attractive shoe
- Only 1 colorway
- Part of the outsole doesn’t seem too durable
- No traction on wet surfaces
- Expensive ($175!!!)
The Newton Gravity 7 is a great pair of shoes for training and racing. It provides a responsive and comfortable ride. It features an action-reaction system with front lugs that might seem foreign to people not familiar with Newtons.
If you’re not used to Newtons, you might want to try slowly integrating Newton shoes into your running routine slowly to prevent hurting yourself.
If you’re looking for a neutral running shoe with a barefoot-like ride with a responsive ride and don’t mind the high price tag, I would recommend the Newton Gravity 7.
I have never worn Newton shoes before. I usually run in Hokas or Asics or some other very cushy shoe. I recently broke my toe (no fault of these or any other running shoe) and I was reluctant to try these shoes.
What this shoe does right?
The Newton Gravity 7 is incredibly light and comfortable.
The tongue is padded, the footbed feels responsive but not hard. They feel like you are not even wearing shoes but have enough padding that you aren’t feeling every bump in the ground.
Where my new Hokas feel like lead weights on my feet sometimes, these Newton Gravity 7’s are a welcome change. I wore these around my house in place of slippers because they are so comfortable and easy to wear.
The toe box is very roomy with plenty of area to splay your feet. The knit upper is extremely comfortable. It is an extremely breathable shoe with hundreds of mesh holes for ventilation.
They have some reflective features on the shoe - in the silver design on the toe and on the decorative swoosh as well. I also appreciate the lack of plastic; the shoe just looks and feels good. The tongue is nicely padded as well.
The colors are attractive with mint green, pink accents and a sparkly white swish on the side or black with teal and white for women. For men, they offer this shoe in tomato red with lime green accents or royal blue with yellow accents. They are not subtle colors but also not neon brights.
What this shoe does wrong?
I was a bit confused about the structure of this shoe at first. On the sole, there is a series of raised black ridges/rectangles.
Initially, I thought these might be shoes for a triathlon, and that was where the bike pedals clipped in. I have since realized that is not the case and this is just a design element particular to the Newton shoes. At first, this raised area felt like a weird lump under my forefoot.
I was expecting to really dislike this shoe. The initial thought was, “Yeah, it’s super light but what’s with the weird lump under the forefoot.” I went on the treadmill, expecting to only be able to wear these for a mile before I had to change shoes. I ended up running 6 miles in these.
As you begin running, the weird black raised area in the forefoot becomes much less noticeable and by mile 4, I forgot it was there. Instead, I noticed that my form drastically improved. I wasn’t slamming down on my heel as I tend to do.
And, after my run, my hips weren’t sore, my knees didn’t hurt and in fact, nothing hurt (when I wear super flat shoes, things do tend to hurt because I’m oldish). My calves felt like they got to exercise- they weren’t sore but definitely different muscles are put in play with these shoes.
The fact that they are so light and responsive makes running seem much more effortless than with a heavier shoe.
On asphalt, these shoes do very well. I don’t have a track but I’m sure they’d be fine on a smooth track surface as well. However, I live in a rural area with a mix of paved and unpaved roads in my normal routes.
These shoes don’t do great on unpaved dirt roads. If you look closely at the pictures of the sole, there was a rock already stuck in the bottom. The grooves spaced just far enough that rocks can get lodged into the spaces and then you have to remove them by hand.
Would I recommend these?
I have now worn these shoes in a variety of conditions and on a variety of terrains. I wouldn’t recommend them for wet or slushy terrain. However, they excel on the pavement and I really appreciate those black ridges on the bottom now, and how they have helped me move away from a heel strike.
These shoes are fast, they are light and they are comfortable. What more could you ask for in a running shoe? I would absolutely recommend the Newton Gravity 7.
Newtons are not cheap, and I have found that they are discounted rather less often than many other brands. I was intrigued by the innovative approach the company took to designing a running shoe.
After much thought, I decided would see if they were worth the price. Whilst I think that overall they are, these shoes do not last particularly long, and this has to be taken into account when considering purchasing them.
I’m a big fan of the way Newton design their shoes. I like the way they combine strong and vibrant colours and produce an excellent looking borderline retro look.
Given that I run a lot at night on city streets, I also appreciate the highly reflective strips on the rear of the shoe as well as the distinctive ‘n’ on both sides of each shoe.
On a technical level, the company boasts that through ‘the active movement of the lugs, Action/Reaction Technology creates a responsive, trampoline-like cushioning system. This system provides quicker bounce-back and loses less energy than a traditional foam-core running shoe.
When you put the shoes on for the first time, they feel quite different from a traditional running shoe. Also, the lugs seem to push you onto your forefoot.
You adapt to the feel quickly. And, due to the design of the sole, I feel my form is always improved when running in these shoes.
These shoes feel taut and give firm support around the heel. They feel well-structured and strong. This is demonstrably true after 300 miles, and they still feel firm and provide good support.
The toebox suits my feet well—neither as wide as my Altra Escalante Racer (admittedly an extreme contrast) nor as snug as my Adidas Solar Boost. These shoes are also reasonably light coming in at 247g. My feet felt well-ventilated and cool even on 10 + mile runs.
Sole and durability
Whilst the top of the shoe looks like new after many miles, the sole and lugs show degradation, which appears more rapid than other brands. This is something that other reviewers also note.
Wear appears to be even across the heel and forefoot areas, but I doubt that I’ll be able to get much more than another 50-100 miles from these shoes.
I rotate these shoes with a pair of Saucony Kinvara 10. I have found that I naturally fall into a rhythm of using these shoes for speed work during the week and then the Sauconys for my long run at the weekend.
This is because the Newtons feel noticeably quick and respond very well in faster sessions but start to feel rather hard on the feet after 10-11 miles.
I generally prefer running in low to zero drop shoes, and I have been really pleased that these Newtons have performed as well as they have.
I can imagine that inexperienced runners would find the sensation of the lug design rather strange. But, if you have some experience with low drop shoes, they quickly feel comfortable. It feels like the shoes are actually telling you to go for a run!
The degradation has to be noted as the rubber on the sole clearly shows wear from approximately 250 miles onwards. That said, I would not hesitate to buy another pair of Newtons in the future despite their generally high price.
Good to know
- The midsole design of the Newton Gravity 7 has identical technology with the previous version. One of the cosmetic changes done in the shoe is the absence of the text on the P.O.P. platform. With this change, the shoe’s performance should remain. It gives runners the springy ride and low offset design that they desire.
- Another primary update was made to the color palette of the shoe. It aligns with the bright pops that the fans of the series have come to love.
- This year’s newest version of the Gravity utilizes a thin layer of Newtonium Cushioning compound. The purpose of this material is for additional comfort and responsiveness.
The shoe runs true to size, and it offers a comfortable and snug fit to medium-footed runners. The Gravity 7 from Newton is available in standard medium D and B widths for men’s and women’s respectively.
The SHARC outsole is integrated into the Newton Gravity 7. It is formed in a phalangeal pattern which aims to deliver increased traction while adapting to the natural movements of the foot. The material is sure to perform well in wet and dry conditions. It provides added durability to the platform as well.
Located in the forefoot area is the high-density rubber. This component of the shoe is focused on providing long-lasting performance that the runner will enjoy.
Better cushioning is encouraged by the high-rebound EVA. It adds durability against the hazardous nature of different paved surfaces.
The Newton Gravity 7 utilizes the new technology called the Newtonium Cushioning System. The foam that is closer to the foot offers a more responsive and comfortable cushioning. This technology is essential in providing the runner with a more efficient and energetic ride.
In the heel and forefoot area lies the Action/Reaction Technology. This component of the shoe offers an agreeable energy return. When the lugs in the external sole unit are compressed, shock absorption is improved, and energy is released during the toe-off phase. This feature also brings a similar benefit to the Newton Gravity 8, which is the latest version of this shoe.
The Newton Gravity 7 uses the Biomechanical Metatarsal Sensor Plate. This sensor plate's primary goal is to increases the wearer’s proprioception. Coordinated movements are encouraged by these proprioceptors. As a result, a better and more flexible ride is promoted.
Enhanced flexibility and full-foot cushioning are offered by the POP1 features of the shoe. Lugs recede into air-filled chambers to provide a fast and responsive underfoot feel. These lugs are acting like rubber bands that push the runner off to their next stride. The energy created from the foot’s heel strike and mid-stance is stored in the external lugs.
The ETC Sockliner is integrated into the Newton Gravity 7. This material plays a significant role in ensuring the maximum comfort of the runner.
The High Rebound EVA works together with the POP1 technology. This material is essential in providing a durable underfoot cushioning to the shoe. It also helps to deliver a more responsive ride.
Stitched to the upper unit of the shoe is the Strobel Last. It offers a more comfortable under shoe feel as well as high levels of flexibility and strength.
The Newton Gravity 7 uses a lightweight and seamless Engineered Mesh. It is focused on allowing better inflow and outflow of air to go through the upper section. This material creates a more relaxed, healthier, and fresher foot environment.
The 360 Degree Reflectivity increases the shoe's visibility during evening runs. This ensures that the runner can be seen, especially in low-light conditions.
An individualized fit is offered by the 4-Way Stretch Mesh Metatarsal Panel. This part of the upper is an essential component of the shoe that adapts to the foot without any restriction.
It has a Heel Lace Lock that provides added security to the foot. It aims to keep the ankle and heel area snug and tight.
The updated mesh tongue enhances the upper fit. It uses a breathable and flexible mesh to provide the right combination of comfort and performance.
The lightweight and semi-flat laces are used in the Newton Gravity 7. Throughout the running activity, a snug and consistent fit are maintained with the help of these laces.
The Newton Gravity 7 utilizes an updated Pre-Molded Heel Counter. Newton added this technology to create a better and improved heel support as well as a comfortable fit and form.
