The Adaptive Fit Advantage

A separate stretchy internal liner offers the best fit adaptability, breathability, and weather protection. Built without a tongue or seams, this slipper-like liner eliminates pressure and hot spots.

The breathable PU-coated nylon upper is cut in one piece and thermolaminated with varying thicknesses of TPU for support and abrasion resistance. The result is a smooth, clean upper that’s lightweight, highly durable, and remarkably comfortable.

Three-dimensional, individually crafted toe and heel pieces are custom-built for each shoe size, delivering precision fit and support, extra durability, and protection that rivals that of a much heavier boot.
