The Nike Zoom Spiridon redefined light weight performance running. Zoom Air, first available in 1995's Zoom Flight basketball shoe joined running properly and the Michael Johnson connection gave this joint fast appeal. Summer use is obvious: The mesh upper breaths easy and the hits of 3M give it some subtle flash. While the OG foil Swoosh is preferable, the less flossy retro versions still come hard. Durability replaces slickness, without changing the tone of a classic. Meaning, essentially, later versions can work for two summers on the trot.
