Nike celebrated the 30th Anniversary of its Air Structure running series by reviving the Nike Air Structure OG. Originally debuting in 1991, it was designed for runners dealing with over-pronation, characterized by the inward rolling motion of the foot. The Air Structure line has since expanded to over 20 models, making it one of Nike’s longest-running series. The refreshed Air Structure OG showcases its heritage with a white mesh upper complemented by grey, black, and Neo Teal Durabuck overlays. Red accents are prominent on the tongue, and Nike branding can be found on the heel and surrounding the Air unit. A white and grey midsole and black outsole complete this retro model. The OG was released in March 2021 for $120. The reissue of the Nike Air Structure Triax 91 OG ‘Neo Teal’ celebrates this iconic model's 30th anniversary, featuring the original colorway. Its upper consists of breathable white mesh, an angular TPU heel clip, and synthetic suede overlays in grey and black. Eye-catching Neo Teal and Infrared accents brighten up the sneaker’s sides, while visible Max Air cushioning paired with a waffle-tread outsole ensures a smooth ride.
