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.?
