The kids' adidas Ultraboost 22 running shoes are perfect for taking the lead, whether your run is a workout or a personal challenge. The BOOST midsole provides endless energy return, and the forefoot is stiffer for propelling you forward and achieving an efficient stride. The Stretchweb outsole allows for a comfortable ride with its natural flex, and the Continental Rubber offers traction on both wet and dry surfaces. This shoe's upper uses a high-quality yarn, composed of at least 50% Parley Ocean Plastic, a recycled material from plastic waste intercepted and repurposed from island, coastal, and shoreline environments. The other 50% is made from recycled polyester.
