Choose the Yeezy Boost if you want more support and comfort. Innovated by adidas and leading chemical company BASF, the Boost is a revolutionary cushioning system which "boosts" your speed and energy. Keeping the sole units consistent with the Yeezy 700s series, the pair features a shade of Orange throughout. The vibrant upper is made of up nylon instead of suede, leather and mesh used on other Yeezy Boost 700 and V2 models.
