How does the Air Max 90 fit compared to the Air Max 1 and Air Max 95?

The AM90 fits very close to true to size for most buyers, slightly more so than the AM1 (which runs long) and the AM95 (which runs slightly wide). If you are between sizes, go half up rather than half down on the AM90; the toe box does not stretch much.

What materials distinguish the Air Max 90 from other Air Max silhouettes?

The AM90 typically combines leather overlays, mesh or synthetic underlays, and a rubber mudguard around the toe cap. The midsole uses a multilayer foam stack with a larger visible Air heel unit than the AM1. Premium colourways like the Light British Tan use velvet and suede overlays.

Is the Air Max 90 QS Volcano a limited colourway or a general release?

The Volcano is a QS (Quickstrike) designation, meaning limited production and no standard retail restock. Once KM's allocation sells through it will not be replenished. QS drops move faster than general-release colourways; check the live grid for current stock.

What styling register does the Air Max 90 sit in: retro sport, streetwear, or something else?

The AM90 occupies a retro sport space that works equally well with slim tapered trousers or relaxed denim. Its chunkier midsole relative to the AM1 gives it more streetwear weight. Tonal or neutral colourways read more versatile; bold hits like the Volcano lean harder into street styling.
