Feel what it's like to stride with a spring in your step. These juniors' adidas running shoes literally add pep to your run thanks to the Light BOOST midsole, a new generation of adidas BOOST with even more energy return. The lightweight feel keeps you going strong through runs of any distance and pace. 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.
