ASICS MetaSpeed MD Size:6 Advanced retro-reflective technology works atTHE FASTEST MID DISTANCE SHOE ON THE TRACK. ASICS FF TURBO, their lightest and most energetic foam, combined with a full foot carbon plate, gives you optimal energy return on every stride in the MetaSpeed Middle Distance Track Spike. Using Motion Wrap technology, this spike keeps your feet in its place, to reduce energy loss during your race. The longer the distance you cover, need more stability you need. Thats why the heel is bigger and flatter.
