Built around a performance last, the Men's Wall Guide Mid GTX Boot is close-fitting for precision and sure-footedness. It features a Gore-Tex Extended Comfort footwear membrane with elastic tongue insert which allows you to put the boot on comfortably and reduces crease-formation. The tip and heel are protected from sharp rocks and scree by rubber. The rubber heel clip reinforces the heel support. The lightweight Gripex Approach outsole provides support, comfort and grip in alpine terrain.
