The Nike Air Max 90 Viotech OG features a Viotech suede, leather, and mesh upper, with the Viotech scheme giving way to bright colors such as red, blue, teal, orange, yellow, and purple. The tongue and collar of the shoe offer mesh construction in teal and grey, complemented by a black and orange Nike badge on the back of the heel, while an Air Max midsole completes the design. Released in August 2019, this model retails for $140. Built with asymmetrical colored panels and the retro running lines of a Nike icon, the Air Max 90 'Viotech' is a can't-miss makeover inspired by a cult Dunk colorway. The upper is constructed of supple suede for street-ready durability and a premium look and feel, with unique color blocking of University Red, Pale Vanilla, and Hyper Grape that mimics the original Viotech Dunk Low from 2002.
