It was already a classic kick, but it just got a remix — a super lightweight midsole/outsole combo keeps you cool and comfortable all day long. Leather and textile upper. Visible Air-Sole unit in the heel for the iconic cushioning you know and trust. PU midsole unit doubles as the outsole, dramatically cutting down on weight. Rubber in high-wear areas of the outsole for durable traction where you need it most.
