This boot features a one-piece water-resistant 2,8 mm full grain leather upper with Gore-Tex® lining which is both waterproof and breathable. The Asolo/Vibram® highly technical sole is comprised of three different PU densities that are co-injected and molded together. The high-density front portion secures and guarantees maximum stability. The medium-density heel reduces shock and resulting fatigue during take-off and landing. Further shock absorption is obtained through the four strategically placed low-density cylinders that are linked from the outsole to the midsole. Gripped with a dual density molded rubber outsole produced in conjunction with Vibram®, the balance of the outsole has self-cleaning lugs designed for optimum performance on varying types of terrain. A micro pulley lacing system helps obtain a secure fit.
