The Magic Speed shoe is designed for racing or regular training runs. It offers the versatility you need to help your body and mind achieve a new personal best. The Guidesole technology is combined with a carbon forefoot plate to propel your foot forward, creating a smooth rolling sensation with every step. Typically, adding more foam to a shoe makes it heavier, but with the midsole drop featuring Flytefoam Blast cushioning, a responsive feel is achieved with each step while keeping the shoe lightweight.
