The Nike Air Rejuven8 is a recovery shoe originally designed for Olympic athletes. The ultimate in lightweight comfort, the Nike Air Rejuven8 provides the utmost relief for feet during the recovery period after a hard workout or long race. Pressure is dispersed equally over the surface of the foot with the innovative TPU and breathable spacer-mesh upper. Immediate underfoot comfort is provided by an 8-millimeter-thick sockliner with a heel air bag molded directly into it. The midsole and outsole are resilient Phylon™ with waffle "pistons" that provide cushioning upon impact. The Nike Air Rejuven8 also uses Nike Considered design aspects to make this an environmentally friendly recovery shoe for all athletes.
