Adidas added more Boost to the Ultraboost 21 Running Shoe to give us maximum cushioning and effortless energy return. The twenty iterations before this version were already incredibly comfortable, but the extra foam and fresh upper feel like a whole new dream. The supportive, mostly-mesh upper grants a secure fit that's intended for comfort through the miles.
