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 each step. Typically, adding more foam to a shoe makes it heavier, but the midsole's drop with FLYTEFOAM Blast cushioning provides a responsive feel with every step while keeping the shoe lightweight.
