Inspired by the Mayfly insect that only lives 24 hours, the Nike Mayfly marathon shoe was originally intended to live a short lifetime—not much more than a little training and marathon race day. Upgraded to outlast its predecessor, the Nike Mayfly Leather Premium 'Legion Green' lifestyle sneaker replaces the ripstop upper with suede and leather. An embroidered Swoosh joins the venation motif that was inspired by the Mayfly's wings. Riding below, a Phylon midsole and synthetic traction lightly support this retro staple.
