Yellow and white ‘Ultraboost 22’ running shoes from ADIDAS by Stella McCartney. Crafted in part from recycled materials, this lace-up model features a PRIMEKNIT upper which ensures perfect fit, a partly-varnished full length cage for added comfort, logo details on the tongue, side and back, and a white and yellow patterned BOOST midsole and a white, black and yellow Continental™ rubber outsole. The Linear Energy Push System increases the flexural stiffness of the forefoot by 15% for a more springy stride. Fully vegan product.
