Seize control. These juniors' adidas running shoes help you take charge, whether you're out for a training run or going for a personal record. The BOOST midsole delivers endless energy return, while a stiffer forefoot ensures forward propulsion and an efficient stride. The Stretchweb outsole flexes naturally for a comfortable ride, and Continental Rubber gives you traction on wet and dry surfaces. 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.
