A retro runner returns in Nike's Air Icarus. Recalling a classic shoe, this refined edition has been updated with nylon and synthetic suede uppers for durable, lightweight comfort – also a reflection of the '90s look. The injected Phylon midsole with encapsulated Air-Sole unit is rounded off by a rubber outsole that provides the essential durability and traction. Synthetic Suede & Nylon Uppers.
