What does women-specific construction mean exactly? For Salomon, it is a shoe that is fully adapted to the morphology of your feet: a softer collar, a wrapping anatomical design, and an ADV-C chassis with lower density for more stability. In the mid-height GORE-TEX version of the X ULTRA™ 4, all of this is complemented by waterproof protection and a grippy outsole that provides excellent traction both uphill and downhill, allowing you to fully indulge your adventurous spirit.
