Finally a narrow shoe for men

This is a great shoe for the trails, best treads ever. This model also fits feet that are narrow. It is not grossly over engineered like the big boy brands, Nike, NewBalance, Brooks, etc.(way too much support on those brands). My only suggestion is on the next model round the toe out it’s too pointed, and add a bit more cushioning.

I Rock

I did obstacles and ran 4 miles on a rocky trail. So far so good. I really like them.

Love this shoe!

These shoes are amazing for super rocky conditions. You don’t even feel the rocks underneath you as you’re running. I was able to wear these straight out of the box and do a 10 mile race with no issues. Didn’t even have to break them in. I found my new favorite trail shoe for where I live.

As hoped for

I have all 3 ocr type VJ'S now since I got the irocks. Went up 1/2 size and they feel great. The deep cleats are similar to my Inov8s but are more comfortable. Cant wait to test their phrase "best grip on the planet" on the slip wall and olympus.

Grippy, responsive and light

Fast shoe for technical, muddy and slippery terrain.
