XTRM

Size Guide
For all your XTRM trails, mud races, or vertical. The best grip, durability and protection for your running needs.

Made for extreme trails...

The VJ XTRM is made for rocky and technical trails where grip, stability, and durability are mandatory.  

The aggressive lugs grip dirt, mud, rocks and anything you run on. The super tough upper is a custom kevlar and polyester weave which provides extraordinary protection and durability. The sole has cushioning units in the front and heel for comfort and a full length rock plate to protect you on tough terrain. 

The XTRM was built for obstacle course racing, trail and sky running and swim run. Use it for tough, demanding terrain in all conditions. This shoe wants to get dirty.

Don't buy if you have need a normal or wide toe box

I first ordered the size I normally wear, way too small. Sent them back, got a size up, and the length was spot on. However my toes were squeezed and wearing them for a few days didn't stretch them at all. Ended up giving them to a very happy lady and bought a pair of Merrill MOAB shoes. They fit perfectly, are the same size, and were $60 cheaper.
