One-piece water-resistant 2,4 mm full grain leather upper. Cambrelle lining. Asolo/Vibram highly technical sole. The outsole incorporates three shock absorbers that correspond with the areas of foot that receive highest impact during activity. These shock absorbers can be identified by their different colour respect to the sole. The shock absorbers are created by combining two polyurethane layers – one of high and one of low density. These layers are individually coloured using a new and innovative technology. Gripped with a 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.
