The Nike Air Max 90 Gore-Tex Anthracite Obsidian is a special edition of the iconic Air Max 90 silhouette, which first debuted in the early 90s. The shoe features a predominantly black upper with grey overlays and white accents. The upper retains the signature Air Max 90 design elements including the layered design, shape of the mudguard and the lace eyelets. The midsole is fully white except for a small area on the heel where the air unit stands, while the outsole is fully black with a small blue patch on the front end. One of the main standout features of the Nike Air Max 90 Gore-Tex Anthracite Obsidian is the use of Gore-Tex technology. This waterproof membrane helps to keep your feet dry in extremely wet conditions while retaining breathability properties for air ventilation.
