Nike Air is a cushioning technology developed by Nike that provides comfort and support in athletic footwear. It features air-filled pockets in the sole of the shoe, which help absorb impact and reduce stress on the feet during physical activities. This technology is commonly found in various Nike shoe models, enhancing performance for athletes and casual wearers alike. The Nike Air system was first introduced in 1979 with the release of the Nike Air Tailwind running shoe. Over the years, it has evolved and been integrated into many popular lines, including Air Jordan and Air Max. This innovation has made Nike a leader in the athletic footwear market.
