Serving multiple purposes, the neoprene upper adds a measure of warmth and comfort. Plus, the neoprene works like a traditional wetsuit for your foot; it lets a small amount of water in, and insulates it so you can comfortably enjoy activities in and around the beach, lake or pool. It also features an antimicrobial treatment that helps combat odor. V-NEOP comes with a removable insole, which can be used to provide an added measure of warmth and comfort. The 3mm minimalist outsole provides a good ground feel. The non-marking XS Trek performance rubber outsole is extremely versatile, with great traction on wet and dry surfaces. The V-NEOP looks and feels great on urban city adventures, and also performs well when used in and around water.
