The Saucony Guide ISO 2 is one of Saucony's older most reliable stability shoes for overpronators. It is now available for £60 since the Saucony Guide 13 recently came out in November 2019.
It is a mid-light daily trainer but could be used in racing for those who need extra support. It is primarily for use on the road but is just as effective on simple trails.
It's a pretty solid shoe and features an outsole, midsole and upper sole protection. It provides moderate to light stability that is unique to the Guide series of running shoes. I have been delighted with it so far!
Most of the Guide ISO 2's stability comes from the midsole part of the shoe. You will notice in the picture below the white strip that runs directly below the arch. This offers great support for overpronators as this part of the shoe is firmer.
And, if your arch rolls over as your foot strikes the floor, the shoe will naturally aid in keeping your foot striking the floor straight, and this will help to prevent injuries from a poor running form.
The midsole also contains PWRFOAM, which is tasked with converting energy from the landing phase into kinetic energy that the foot can energize during lift-off.
Considering it's a pretty stable shoe, it's also light, weighing in at 292g for men and 255g for women.
As soon as I tried these shoes on, I noticed a difference in my running mechanics (this was conducted on a treadmill with a specialized team of running experts). Instantly, my overpronation stopped, and my foot strike was better.
Grip & durability
The outsole part of the shoe is covered with a rubber compound called XT-900. This layer protects against wear and tear and provides excellent traction over surfaces.
It also contains a layer of IBR+. This is particularly important as this is what gives the shoe the sponge-like feeling whilst running over any terrain.
As you can see from the picture below, the tread of the shoe is designed in zig-zag grooves, which give a smooth transition to the toe-off phase of the gait cycle.
I have used my Guide ISO 2 for over 450 miles now, and the soles are still in great condition!
The shoe that hugs your feet
The upper unit of the Guide ISO 2 contains an ISOFIT foot-hugging technology (this was my favourite part of the shoe). Not only did the shoe correct my running mechanics, but it also felt remarkably comfortable.
The stretchy mesh and overlays really helped to make my feet feel secure and to give me the confidence I needed whilst running over more harsh terrain.
I found the support around the ankle area was strong enough to feel confident but not overly harsh that I found it uncomfortable. Whilst the shoe offers good overall support, it does not over constrict your foot's movement.
It offers a nice toe box, which works well for me, and I have avoided any blisters even on my longer runs of marathon distance. Pictured below is another example of how durable the shoe is.
This picture has been taken after over 450 miles of running in the shoe, and as you can see, only minimum damage is done to the mesh part of the shoe.
Another thing I really like about the Guide ISO 2 is the comfy heel fit you get. It is sturdy and well fitted but did not require any breaking in.
I can think of lots of shoes I've had to break in and ended up getting lots of sore, blistered skin on my heel. I didn't get this with this shoe. I literally went straight into a few shorter runs to test it and was easily able to start back with the longer distances right away.
Even after running plenty of miles in this shoe and being a bit lazy by putting it back on without untying the laces (we all do it), it's still solid and not lost its shape as some others do.
Saucony's quirky colour range continues with the Guide ISO 2. I was drawn to this shoe out of most of the others in the running shop I went to.
The sleek design of the upper mesh makes the shoe appear aesthetically pleasing. It's a thumbs up from me!
So far, for me, this shoe has been perfect. It's been comfortable even up to marathon distance. It's been reliable whilst running on road and some light trails.
I have yet to have a blister caused by the shoe. I did get one a few months back, but upon further investigation, I noticed there was something in my sock.
It's been my favourite shoe for a long time, and I generally think I have got every pennyworth out of the shoe so far (I did get a good deal).
I should really retire this shoe soon as I am approaching the 450-mile mark, but I'd like to see how far I can take it before I feel it needs to be changed.
I already have my eye on its successor, and if its anything like this shoe, I'll be well impressed!
Good to know
- The Saucony Guide ISO 2 is a running shoe that’s meant for the roads. It is also designed for those who have overpronated foot motion. The underfoot platform is composed of two full-length foams that work together to provide a steady and comfortable base for the foot. A medial post supports the arch, saving it from rolling inwards too much.
- The upper unit of this stability shoe is made of stretchy mesh that accommodates the natural shape and movement capacity of the foot. A moisture-managing internal lining prevents sweat from staying in the padded contours.
The Saucony Guide ISO 2 is true to size. Runners are encouraged to get the size that fits them the most, though trying out the shoe first before making a purchase helps in attaining a comfortable experience. Widthwise, the available options for men are D – Medium and 2E – Wide; the women’s version has the B – Medium and D – Wide variants.
The high-wear areas of the Saucony Guide ISO 2’s outsole unit are covered by a rubber compound called XT-900. This durable layer is meant to protect against wear-and-tear. It is also tasked with providing traction over the surfaces. The XT-900 rubber is also placed in the outsole of the Omni 16 and other durable shoes from Saucony.
IBR+ is a layer in the forefoot that’s made of blown rubber. It protects against abrasion, yet it also contributes to the overall cushioned feel through its spongy construction.
Tri-Flex is a design that focuses on the flexibility of the outsole. It involves a convex forefoot design and zigzagging grooves that facilitate a smooth transition to the toe-off phase of the gait cycle.
PWRFOAM serves as the base of the Saucony Guide ISO 2’s midsole. It is tasked with attenuating impact shock during the landing phase and converting it into kinetic energy that the foot can use to energize the liftoff.
EVERUN™ is used as a topsole, and it’s meant to put more liveliness into each step. It has a bouncy nature that encourages the foot to push off the ground with fervor.
A stability post is added to the medial side of the platform. This dense EVA (ethylene vinyl acetate) hunk is made to correct overpronation. It also prevents the tendons and muscles of the underfoot from being strained.
The FORMFIT is a sockliner that adds some more cushioning for the underfoot. It follows the contours of the foot-pad, thereby supporting the curves that aren’t usually given any attention.
The upper unit features the ISOFIT foot-hugging technology. This system of stretchy mesh and overlays adapts to the shape and motion of the foot, thereby giving a secure yet agreeable coverage.
The RUNDRY moisture-wicking fabric outlines the interior sleeve. It is meant to prevent sweat from seeping into the walls of the upper unit, staving off odor in the process.
