This shoe features a waterproof nubuck leather upper, certified by the Leather Working Group, combined with a Gore-tex membrane to enhance moisture repellency to keep the foot dry over time. This model also uses recycled polyester for the strap, mesh inserts and laces. In addition, the PU molded sockliner is made of 50% soybean oil, while comfort is enhanced by the presence of a compression molded EVA foam midsole and the extended heel that cushions impact.
