Got cuff-fit issues? Testers loved the X-Pro’s flared liner top and adjustable calf volume. It fits average-to-wide calves without any adjustment. We got even more cuff room using Salomon’s Custom Shell process, which adapts to fit a huge range of foot widths. (The X-Pro could hold its own in the Medium Fit category as well.) Testers called it sensitive, reactive, and agile. The flex is even, smooth, and a bit softer than its 90 rating.
