The METASPEED™ Sky racing shoe moves you towards a sound mind and a new personal best. It's designed to help you go faster by extending your stride length. Stride-style runners take a longer stride once they start increasing their speed, but their cadence primarily remains consistent. Thanks to an energetic midsole foam and a propulsive carbon plate, runners wearing these shoes will be able to conserve more energy while maintaining their pace at the later stages of the race. *These shoes are in mint condition. Have only been worn twice for light runs*
