Nike Women's Gas-Inflated Shoes The Nike Air 97 Universal Women's Sports Shoes are another continuation of the famous line that dates back to 1987, when the first Nike Air model was released. The shoes are characterized by a special filling of the midsole with compressed gas to induce excellent shock-absorbing properties in the key mid-back area. Specifically, the Nike Air Max 97 model is based on the original model from the second half of the nineties. This is also reflected in the characteristic design, which was inspired by the shape of Japanese high-speed trains. The shoes are made of strong and precisely stitched materials, while they are decorated with distinctive reflective elements of aerodynamic shaping all around. The light foam midsole is also wavy shaped. The sole is covered by durable abrasive rubber of a classic urban pattern with a guiding center line. Material: Synthetics, textile, EVA, rubber
