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.

Tight shoes normal feet

I purchased these shoes along with the Saucony Kinvara 7. I intended to use the Zealots for my long distance runs and Kinvaras for shorter, faster distances. I have put 106 miles on the Zealots as of today (tracked on Strava.) I expected the cushioning to soften as I broke in the shoe. That never happened. Zealot cushioning is hard when running, but soft when walking. They sound and feel like clogs running on the sidewalk path. Also, they are very tight around the middle of my foot. The ISO technology is too tight and makes the shoe uncomfortable. My feet have become numb during the run and sore after. I can not return the shoe now. The zealots are not bad for short walks, so I will use them for that activity. The shoelaces have also frayed, substantially. Too Bad. I will not buy Zealot again.
