The waterproof Perwanger leather upper offers protection and comfort, while the Gore-Tex Performance Comfort provides waterproofing and breathability. The outer sole consists of a dual-density Eva midsole: the first density is harder to offer support and stability, while the second is softer to ensure comfort and absorption. The Asolo/Vibram outer sole has a self-cleaning design and uses the MegaGrip compound that provides amazing traction and performance on wet and dry ground.
