Featuring a light atop fit system, the Santic J1 Edition Road Bike Shoes offer on-the-fly micro-adjustment, backed by the atop guarantee. To ensure a more-than-perfect fit, they are equipped with a Velcro front closure that makes it easy to fine-tune the fit while in the saddle or when stopped at a roadside vista. The perforated synthetic leather composite upper is lightweight and offers superior breathability, keeping your feet cool and dry even during the most intense rides.
