Sensitive. Aggressive. Affordable. The X1 offers more sensitivity and "feel" than any shoe on the market without breaking the bank. Built on a medium volume, downturned and down cambered last, the X1 is built for training hard in the gym and sending hard outside. The single hook and loop strap closure make it easy to get on and off. The Trax® SAS outsole and massive toe patch give the X1 a true "sock" fit and feel on the wall without sacrificing a secure fit.
