Feather-light, to help redefine the concept of fast. The adidas Crazyfast .1 Laceless are engineered to deliver acceleration that bends the game to your will. The Aeropacity Speeskin upper is so light, it's almost translucent. Aerocage reinforcements are sued only in key internal areas to deliver support for those quick changes of direction. The outsole features additional arrowhead studs and an Aeroplate inlay to extra energy return that propels you forwards.
