New to the Chris Sharma Signature Series is the Nexxo. It represents for Evolv a new way of approaching how we build shoes, how we engineer performance and how we bridge to a higher level of design. It is soft yet it is powerful. It is convenient and it is precise. The Nexxo ushers in a new era of Evolv's Ultra-Performance climbing footwear.TRAX® RubberTRAX XT® high friction rubber is formulated to be the highest performing rubber on the market. TRAX XT®has a perfect balance of high friction and edging power on different types of rock and plastic holds while performing consistently over a wide range of temperatures. evolv continually works towards being environmentally conscientious and sustainable. We realize that due to the nature of manufacturing we can never be fully green, but we strive to do our best to minimize harm to the environment. With this goal in mind, evolv and TRAX® Rubber have developed eco-TRAX, a recycled content high friction rubber compound and started using it on products beginning Fall 2008, making evolv the first climbing shoe company to use a more environmentally friendly rubber on climbing shoes. The technology comes from decomposing selective pre & post consumer rubber waste and then reprocessing it to make a useable compound. Currently, 30% of the eco-TRAX compound used on select parts of outsoles is recycled material, however we plan to use a higher recycled percent compound on other applications that don't require maximum friction. VTR3DWith VTR3D, the high wear zone of the rand is thicker, while low wear areas are kept thin to reduce pressure points and hot spots around your foot.
