No need to sacrifice style for functionality here. PU Coated Fabric Rubber Artificial Suede Leather - The artificial suede leather provides comfort and softness around top closure of a product. Composition Upper - 80% Leather, 10% Polyamide, 10% Rubber Sole - 100% Rubber Waterproofing & Breathability OutDry - OutDry uses a one-piece patented construction that creates a waterproof and surprisingly breathable barrier. This impenetrable layer is heat-bonded directly to the outer fabric, leaving no seams or gaps, and no way for water to get in. OutDry technology ensures the outer fabric won\'t pick up water while improving fit and dexterity, resulting in a lighter, more comfortable boot - and a drier foot. Protection Rev It\'DSF (Dynamic Support Frame) - The unique, in-house developed Rev It\'DSF (Dynamic Support Frame) offers maximum levels of protection without sacrificing comfort. The DSF limits hyper extension of the tendons and muscles. The three key components - the calf support, heel cup and stability frame - all work together as one system, allowing you to ride comfortably in any terrain, without worrying about your safety. It also provides flexibility and freedom of movement off the bike. External TPU Shin Plate - The External TPU Shin Plate provides additional protection in the shin area against impacts of objects and debris. SeeSoft at Tongue - The SeeSoft protectors reduces the energy transmitted to your leg by the impact of rocks and other road debris that may strike you while riding. Toe, Vamp, Quarter and Heel Reinforcements
