Air Structure Triax 91 OG 。Nike sporty, eye-catching colorway The Triax 91 is the first sneaker in Nike\'s Structure series. This series is designed to provide stability for runners who are over-pronating. This means that a runner\'s foot tilts excessively at times when it should not. The sneaker quickly became popular because of the two colours used on the upper, which were very rare at the time. Even the Air Unit was different on the outside than on the inside of the shoe Introducing the Nike Air Structure Triax 91 OG Neo Teal 2021 sneakers, a must-have addition to any sneakerhead\'s collection. These iconic sneakers from Nike feature a stylish neo teal colorway that is sure to turn heads. With their OG design and comfortable fit, these sneakers are perfect for both casual wear and athletic activities The 2021 reissue of the Nike Air Structure Triax 91 OG ‘Neo Teal’ brings back the original colorway of the vintage runner on the occasion of its 30th anniversary. The upper is constructed from breathable white mesh with an angular TPU heel clip and synthetic suede overlays in grey and black. Mismatched accents in Neo Teal and Infrared enliven the sneaker’s lateral and medial sides, respectively.
