What happens when you take the iconic Ultraboost and go "creator mode" on it? We did just that and came up with these juniors' everyday running shoes. The responsive BOOST midsole is enhanced with 3D Stretchweb that wraps around it for a trampoline-like feel underfoot. adidas PRIMEKNIT hugs the foot for all-day comfort. The futuristic look? That's all for style. 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.
