The Master outsole, developed in collaboration between Asolo and Vibram, utilizes a TPU top film to protect the heel material, and a PU heel for cushioning. The microporous midsole is integrated with the heel to provide an ideal balance of support and stability, and the Vibram Mount rubber on the outsole gives the boot excellent grip on varied surfaces. NOTE: The sturdy construction of the boot requires a gradual break-in period.Sold in pairs, the Asolo Men's Power Matic GV EVO boot is available in men's full and half sizes. To keep the leather on this boot in good shape and to prevent water absorption in the upper for the life of the boot, you should apply a leather conditioner or wax paste waterproofing treatment (both sold separately).
