The adidas UltraBoost 22 'Black White' treats the performance running shoe to a blank-slate finish. The form-fitting upper is constructed from black Primeknit composed of 50% recycled Parley Ocean Plastic and 50% recycled polyester. A matching white Boost midsole is enhanced with adidas' Linear Energy Push system, which provides increased energy return by lessening forefoot flex. Underfoot, the Stretchweb outsole features Continental Better Rubber for superior traction on wet or dry surfaces.
