The MAGIC SPEED™ shoe is made for racing or regular training runs. It offers the versatility you need to move your body and your mind towards a new personal best. Made to propel your foot forward, GUIDESOLE™ technology is combined with a carbon forefoot plate. This creates a smooth rolling sensation as you move through your stride. Traditionally, when you add more foam to a shoe, you add more weight. By stacking the midsole with FLYTEFOAM® Blast cushioning, this material adds a responsive feel to your step while keeping the shoe lightweight.
