Handcrafted to provide a wider platform, Mountain Pass's legendary stitchdown construction offers increased stability underfoot. Many of our stitchdown boots can be recrafted. Handcrafted construction together with a Vibram® Kletterlift Thin Outsole create a very strong combo. The Vibram® Kletterlift Thin Outsole was specifically designed for comfort and durability for everyday use, while reducing height and weight from the traditional Kletterlift outsole.
