Our interpretation of where tech meets fashion and performance meets design, the Extent NITRO™ features a full-length, lightweight nitrogen-injected midsole that’s encapsulated by a heel stabilizing foam to create an aesthetical and technical balance. In the Ultraviolet iteration, the textile upper contains iridescent details and a fading effect on the midsole, and the shoe is designed and constructed around the idea of caging, thanks to a hidden supporting structure that holds up the lightweight fabric.
