What does women-specific really mean? For us, it’s shoe that is fully adapted to the morphology of your feet: a softer cuff, cradling anatomical design and lower density ADV-C Chassis for greater stability. In this mid-cut GORE-TEX version of the X-ULTRA 4, all this is backed up by waterproof protection and a grippy outsole that powers through uphills and descents, so you can explore every angle of your freedom. Improved stability The new ADV-C Chassis targets articulations on the outer foot to optimize stability without limiting your mobility, while the higher cut provides extra ankle support. All-terrain grip The Contagrip MA outsole grabs the terrain, even when it’s wet or slippery, giving you more control especially on descents. Women-specific With softer materials, especially around the collar and heel, a lower-density chassis and bigger last, this shoe is designed for women’s feet.
