The adidas UltraBoost 19 running shoe is so comfortable, its second-skin fit makes running seem easy. A follow-up to the UltraBoost, this style is designed with a popular black and white color combination. Black covers the upper along with the updated webbing system, Three Stripes, and ergonomic heel clip, while white is seen on the Boost midsole. The adidas Primeknit 360 upper is ultra airy with stretchy, woven material that fits like a sock. Dual-density Boost cushioning provides a responsive ride and embedded Torsion Spring in the midsole helps propel the foot forward.
