You'll be an adventure-loving explorer in the Ahnu Sugarpine Boot. Incredibly lightweight, yet extraordinarily supportive, this lightweight women's boot features a waterproof leather and synthetic textile upper with moisture-wicking nylon lining and an Aegis® antimicrobial-treated footbed cover to help the interior remain fresh. Seam-sealed, waterproof membrane construction protects you from the elements. A removable, multi-density insole rides atop a lightweight, polyurethane midsole with built-in heel stabilizer and supportive nylon shank to balance your natural stride, while the Vibram® rubber outsole of the Ahnu Sugarpine Boot provides high-surface contact to ensure reliable traction on smooth surfaces, even in wet conditions.
