Shimano SH-R321 Shoes (Wide)

When you have your sights on the podium, Shimano’s R321 shoe ensures the interface between your body and bike is seamlessly without compromise. If, like many others, your wide feet been underserved by high-performance road cycling shoe offerings, the R321 Wide is for you. Its woven carbon fiber sole utilizes a hollow channel feature to decrease weight and increase power transfer capabilities, giving you an ultra-lightweight platform that sends every watt to the pedal. You'll be blown away by the personalized, foot-stabilizing fit that comes from the heat-moldable Teijin Avail 100 synthetic-leather surround upper, Custom-Fit ergonomic heel cup, and customizable arch support insert. Even the top strap has adjustable anchor points to offer support exactly where you need it for comfort and power transfer. When fractions of a second determine victory or defeat, trust Shimano’s R321 to help you get your tire across the line first.
