Released on May 30th, 2019, the Nike Air Max Tailwind 4 'Metro Grey' reveals its infamous ribbed aesthetic in a coordinated, classic colorway with gold trim. This fourth iteration of the Air Max Tailwind running lineage is the first to sport Max Air cushioning under the forefoot as well as the heel. The front-to-back cushioning was inspired by the Air Max 95; its asymmetrical design, distinct ribbed midfoot construction and waffle outsole make it a running legend.
