Grip and then some...

The iRock 3 is made for technical trails and obstacle course racing. It has the grip and control you need for the gnarliest of terrain.  

Our most aggressive, deep lugs give you the best grip in the worst conditions. This lower profile shoe gives you exceptional feel for the terrain. The upper is made of breathable sandwich mesh reinforced with strong kevlar fibers. It is built on a narrow last for a snug fit.  

The iRock 3 is superb for obstacle course racing, Swim Run (or Swim/run), Sky Running, VK’s, and trail running.

Great Trail Runners

Awesome shoes even though they are a bit narrow for my wider feet. They are reliable on the trail which is the important part but expect there to be an adjustment period before you break them out for a run.

Runs Small

I love the shoes! They are super comfortable to run in and they have amazing grip! The only issue is that they run extremely small. I normally wear a size 7 and had to order a size 8.5 for them to fit correctly.

Unreeeaal!

I have the MAXx and thought I'd give these a try. I was a bit concerned from all I had read about them being a bit narrow. I went up a half size (as I did with the MAXx) and I cannot tell you how comfortable these shoes are... In fact as I was walking out of the Vegas Sprint last weekend I had that exact thought! Unbelievably comfortable, killer grip (duh) and they just performed perfectly. Highly recommend!

Holy grip

For starters, these are incredibly comfortable. The lower profile makes them feel like they are part of my feet. But the best part? The grip is INSANE. I live in central New York and am able to hit snowy trails with such ease. Even the crunchy, icy patches are no match for these. They make me wish the trails were snowy all year.
