What is adidas air?

As an AI language model, I can only assume you meant "Adidas Air" as there is no such product named as on the market. My assumption is that you are looking for information on Adidas' cushioning technology. So, Adidas Air does not exist in the market, but Adidas has its specific cushioning technologies, such as Boost and Bounce, engineered to offer comfort, support, and responsiveness for different types of sports and activities. Adidas' Boost technology uses thermoplastic polyurethane (TPU) pellets fused together throughout the midsole to provide energy return and cushioning, whereas Bounce uses a proprietary foam that is designed for durability and cushioning under high-impact conditions. Both technologies aim to offer a responsive and comfortable experience to athletes and consumers alike.
