This shoe features a Dream Knit upper that hugs your foot but also helps regulate your foot temperature and control odor at the same time. A short, lace-up panel lets you adjust the width to what feels right for your activity level while a knit band at the ankle keeps the shoe securely in place. A ventilated outsole constructed of dual-density polyurethane also helps keep your temperature just right. The TRAQ technology turns the Qool into your own personal pedometer whenever you wear it. No charging necessary, just connect to the free TRAQ smartphone app and go.
