About this product
To meet the requirements of female athletes, the Stella McCartney x Wmns UltraBoost X 'Solar Yellow' sneaker was designed using motion capture technology and input from the English fashion designer. Released in July 2018, the runner is fitted with an adaptable Primeknit upper reinforced by a flexible arch underneath. The shoe swaps traditional laces for stabilizing Velcro straps. The revolutionary Boost sole delivers plush, responsive cushioning.
