Thanks to an innovative boot-within-a-boot design, these high-country mountain hunting boots wrap your feet stabilizing comfort. Inside the full grain nubuck leather uppers, MFS Vakuum foam panels form to the shape of your feet, ensuring a perfect fit without uncomfortably tights pressure points common in lesser-made technical boots. Special stretch Gore-Tex, waterproof linings do away with standard heal seams, eliminating yet another potential blister-forming hot spot. Between the Air-Active insoles and gripping Vibram Alpin outsoles, polyurethane midsoles push you through each step while allowing for the addition of soft crampons.
