About this product
Black and white meet on the Mostro in a straight, high-contrast pairing. Rubber and textile form the upper, putting a firm, smooth material alongside a softer woven one. Rubber has a uniform surface that wipes clean easily, while textile brings a woven, matte texture. It is a men's model.
