 Whether you ride with an SPD system or standard road bike pedals, the Tri X-Speed IV fits them both. No matter if your feet are thin, medium or wide, Garneau's X-Comfort Zone technology prevents numbness by extending the shoe's edges if needed. A wide foot entry makes it easy to perform those first hop-on-the-bike transitions, and 0 hook-and-loop straps help to attach your feet and start pedaling in no time. A breathable and ventilated insole takes care of getting your feet dry after the swim and keeping them that way until you hit the run, on your way to reaching your triathlon goals.
