We've all had to sacrifice comfort for race speed at some point, but that is a thing of the past with the RC Evo Supersonic Shoe. Developed with pure race speed in mind, the RC EVO Supersonic combines a stiff carbon outsole with a lightweight, ultra-comfortable airmesh upper to enhance your overall performance. Superior sole support is also provided with the ErgoLogic insole that can be adjusted or removed to ensure the best arch support for your foot shape. Finding the perfect snug fit with the dual BOA Li2 adjustment system is simple and allows for easy adjustments while on the go.
