Some kids only have one pace - fast. That's why we made these kids' Ultraboost shoes with all the best tech from adidas Running. BOOST in the midsole feels soft and responsive, the adidas PRIMEKNIT upper hugs the foot and grippy traction holds to any and every surface. Now they can tackle school days and weekend adventures in total comfort. This shoe's upper is made with a high-performance yarn which contains at least 50% Parley Ocean Plastic - reimagined plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
