Nike Air Force 1 Low SP Undefeated Multi-patent Wild Berry is a low silhouette with integrated Nike Air cushioning. Bruce Kilgore designed the Air Force 1 in 1982 as Nike's first basketball shoe with Air technology. It soon moved from the court to the street and became a fixture of sneaker culture. A padded collar lines the heel. Nike Air works inside the midsole, while solid rubber forms a durable outsole. Regular perforations divide the toe. By combining flexible foam with a durable contact surface, the complete build supports comfort without losing firm contact with the ground.
