Adidas UltraBOOST Running Shoes Feel the power of your best run in these 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 everyone knows 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. Boost Midsole Adidas take cushioning to new heights, with their ultra-responsive midsole: Boost. Tiny TPU capsules are moulded together to form a platform that is different to standard, solid foams; absorbing energy and then expelling it back out for a bounce-like effect. 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 you 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. StretchWeb Outsole The midfoot Torsion System exists to let the forefoot and rearfoot move independently; the result is protection, control and an easy heel-to-toe transition. Manufactured from Continental rubber, a StretchWeb outsole completes the UltraBOOST. Its web-like structure cooperates with Boost to allow the shoe to stretch, for a flexible and lightweight underfoot feel. The web pattern also means a large surface area, and this means better grip.
