Air Jordan 9 Retro "Flint Grey and French Blue" Little Kids' Shoes FLIGHT LIKE MJ. Flint Grey. French Blue. You know the one. Back for the first time since '02, this modern update revives the classic colorway while keeping all the iconic details intact. It's all there - The minimalistic leather upper, the "one-pull" lacing system, the jagged midsole. Genuine leather in the upper adds durability and structure. Rubber in the outsole helps give you durable traction.
