Adidas UltraBOOST Women’s Running Shoes Feel the power of your best run in these women’s running shoes. Built with ultra-cushioned Boost and a foot-hugging upper, for the athlete who craves a light, cushioned, energy-packed ride. Primeknit Upper A Primeknit upper will encase each foot in breathable comfort. Its seamless construction provides an irritation-free fit, because we recognise how rubbing and blisters can ruin your day. Light in weight and designed with motion in mind, Primeknit adapts to the changing shape of your foot through the gait cycle. A supportive cage secures the midfoot, reducing in-shoe slippage for a smooth, distraction-free ride. The FitCounter, a split, moulded heel counter, promotes a natural fit; allowing for optimal movement of the Achilles while still providing support.

This energy return technology reduces the use of superfluous muscle power, diminishing fatigue and enhancing performance; keeping you going for longer. The plush, responsive cushioning will spare your joints as your sprint down onto hard, unforgiving concrete. Boost also manages to maintain its special function and bounce in conditions as low as -20 degrees, making it a reliable, durable and hard-to-beat midsole.
