Originally released by Nike as a lightweight marathon shoe with a 100km limit, the Mayfly reemerged as a lifestyle shoe back in 2013. This year, the retro sneaker will be released again in a modern white and blue colorway. The shoe's new design features an off-white suede upper, Vanchetta Tan leather on its heel, and staggered blue graphic print meant to resemble the pattern found on the wings of mayfly bugs. The new Mayfly is designed with a breathable mesh upper, a phylon midsole for light support and rubber outsoles for added traction.
