The Nike Mayfly debuted in 2003 as a marathon shoe intended to expire after 100km, taking inspiration from the aquatic insect known for having a short lifespan. A quickstrike release from May 2017, this 'Fiberglass' version is modernized in suede with signature woven details and a matching leather heel. The molded rubber midsole is set atop a gum outsole for a vintage-inspired feel.
