Running is all about forward momentum, and these shoes are designed to make it feel effortless. The 3D-printed 4D midsole has targeted zones of support and absorption, finely tuned for propulsion. The result is a smooth ride that feels more like gliding than stop-and-go pounding on pavement. adidas PRIMEKNIT gives a foot-hugging fit, and the grippy rubber outsole provides traction on wet and dry surfaces to keep you going in all conditions. Brand new in box. Price is firm.
