Slightly too small at size 9 so only wore a couple times (I’m more a 9.5 now). Features: This mid-cut boot features GORE-TEX Extended Comfort for waterproofing and breathability, a suede leather upper with protective rubber edging, and a Vibram Hike Approach sole for various terrains. Technologies: It integrates Salewa's patented technologies like the customizable Multi Fit Footbed Plus (MFF+) for adapting to foot shape, Climbing Lacing for precise fit, and the 3F System for ankle and heel support.
