Shimano R088 Wide Road Cycling Shoes. The Shimano R088 Wide road shoe meets all the demands of the discerning club or recreational cyclist. A durable, stretch resistant synthetic leather upper provides a snug fit, the upper's breathable mesh keeps you comfortable in warm weather, and the micro adjustable buckle plus dual off set straps provide an incredibly comfortable fit to enhance pedaling efficiency. And speaking of efficiency, the R088 Wide's foundation is a low profile, lightweight fiberglass reinforced polyamide sole that's plenty stiff for optimizing your power output. The adaptable cup insole as well as the Shimano Dynalast accommodates a wide variety of foot shapes. And since the shoe is both 3 bolt and 2 bolt pedal system compatible, you'll be good to go for outdoor riding as well as indoors at a spin class.
