women-specific morphology. X-Ultra has a softer cuff, cradling anatomical design and lower density Advanced Chassis™ for greater stability. In the women’s X-ULTRA 4, all this is backed up by a grippy outsole that powers through uphills and descents, so you can explore every angle of your freedom. Good for day hiking on mixed terrain. Height-Low. Foot protection-High. Foot support-Stable. (Info from Salomon website) These have a larger toe box than most Salomon shoes have. Great shoe just ended up being too big for me. Online order that I couldn’t return. Tried on for a few min, never worn otherwise.
