Ultraboost 21 Shoes
The definition of best never rests. It continues to move. When we dropped the first adidas Ultraboosts, they were the best running shoes we ever made. With each new update, we raised the bar for comfort and responsiveness. This version includes a Linear Energy Push system, which helps you roll through the heel-to-toe gait cycle for an extra push of energy in every step.
This product is made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic.`
