Step In, Strap Down and Go The heel of the shoe partially collapses when you step in, effectively widening the collar to make getting in extra easy. A large strap connects to the laces and fastens to the side, letting you secure the fit with 1 hand. Go the Distance A full-length Air unit is stitched to the upper to help reduce layers and overall weight while bringing the cushioning right up under your foot. There's also a forefoot Zoom Air unit that returns energy with every step. A foam insole helps to smooth the sensation. Pivot, Jab and Cut The outsole pattern uses contoured lines that bend and deflect in multiple directions to help you gain traction and always feel connected to the court.
