Saucony 4mm Technology

Shoes with a 4mm heel-to-toe offset deliver a more natural ride, letting your feet and body do more work while relying less on the shoes’ cushioning and stability features.

A strong, lightweight material is melded to the upper, which allows for fewer layers in the shoe. The result is a seamless, flexible feel.


Saucony ISOFIT Technology

Revolutionary fit system that morphs to the foot for a custom feel.


Saucony PWRGRID+ Technology

Proprietary midsole technology offering 20% more cushioning.


Saucony TriFlex Technology

Increases force dispersion over a greater surface area while also delivering optimal flexibility and traction.

My local running store special ordered these after I went through 2 pairs of the Zealot 1. I ran in these in the Summer for a month and found them to be too hot. Sweat soaked and heavy feeling and just less firm and more, sluggish feel to them compared to the version 1 really bothered me at first. I set them aside for Winter. After trying brooks Launch for a while. Now I just revisited them in the winter months starting in November. In the winter I am enjoying them quite a bit more. The tread does wear faster as some other reviewers point out, but the positive side of a faster wearing rubber is it is stickier/grip improved over version 1. This is helpful in the rainy Northwest in Winter. Also when the air is colder, I am appreciating the plush ride much more. The new cushioning is really nice for winter runs in dark or just leaves/puddles where I cannot see footing as well. Also the cooler to cold temperatures really seem to feel better with more cushioning. I understand ISO footbed is related to boost midsole which does not get too firm in colder temps and doesn't break down as fast as other foams. For me at least, I love that both this shoe and the prior shoe offer some premium cushioning in a shoe that has a 4 mm drop. The 4mm drop makes a difference for me, improves my form, involves my glutes/calves more and I actually get less injuries compared to running in 10 mm traditional drop shoes. These shoes have just enough bounce/to firmness in them to be able to train pretty fast (they still feel slightly heavier/slower than version 1) but also enough cushion to prevent injuries in a guy my size. I am still at 34 years of age a 6 minute/mile road race pacer over the 10K-half marathon distance (almost all I run these days), In these shoes I usually can run 6:30-7:30 tempo runs without feeling like the shoe is slowing me down too much though for true speed work would suggest you move to the Kinvara. Of note, I am a heavier 'muscled" runner compared to most "faster" runners. I trend just above or below 180 lbs and am just under 6'. People mention the forefoot fit is tighter. I agree with this but would say it is just slightly tighter not extreme. If you have very wide foot you might need to see if can order custom or size up 1/2 size.
