The Mayumi Yamase x Air Force 1 Flyleather ‘Earth Day’ released as part of a collaboration with the Tokyo artist. A sustainable take on the classic silhouette, the shoe features inspiration from Yoyogi Park in Shibuya, Yamase’s local green space. As a result, mismatched accents drawn from natural elements highlight the look throughout, including hand-painted Swooshes and abstract figures. The upper itself is built with 50% recycled leather fiber, while underfoot, Air in the heel of the translucent rubber cupsole provides cushioning.
