The adidas Ultra Boost Junior "Ash Silver" running sneaker delivers lightweight comfort in kids sizes. A multi-colored Primeknit takes over the upper, and a white Boost cushioning sole handles the bottom to create a versatile look. A grey tonal cage and heel overlay create support that holds the foot in place, and the innovative material resembles a ribbed knit. Embracing functionality, the adidas Ultra Boost is a neutral running shoe designed to give the wearer the ultimate running experience.
