Air Max 90: real vs fake

The Air Max 90 launched in 1990 as the Air Max III and became an icon thanks to its visible Air window framed in bright TPU. That exact zone — the window, its segments and the plastic frame — is what most often exposes a fake, because precise molding is hard and expensive to copy.

What to check on the Air Max 90

Model-specific zones — on top of the brand-level signs.

Air window segments

The authentic visible Air window is clear, with crisp, even internal dividers of equal thickness. On fakes the window is cloudy or yellowed out of the box, the segments are crooked, or their count does not match the original.

TPU frame around the window

The plastic frame around the Air unit is molded smoothly, with even paint and no bleed onto the clear section. Plastic flash, stepped joints and paint on the window are typical replica defects.

Ribbed midsole segments

The ribs on the midsole around the heel run at an equal pitch and identical depth. On fakes the pitch drifts, and the ribs are either smoothed over or cut too crudely.

Layered toe panels

The AM90 toe is built from several overlapping panels (mudguard, suede/leather, mesh) with a clean boundary between layers. On fakes the panels are thinner, the boundary collapses and the stitching puckers the material.

Nike Air heel logo

The Nike Air branding on the heel keeps exact proportions: the Swoosh is not tilted up and the letters are not stretched. A warped mini-Swoosh on the heel is a quick fake marker.

FAQ

The Air window on my pair looks slightly cloudy — is it fake?

Not by itself: on worn or older pairs the window can haze or yellow with age. It becomes suspicious when a cloudy window on a brand-new pair combines with crooked segments and an uneven TPU frame — that points to a replica.

What should I photograph first on an Air Max 90?

A close-up of the Air window from the side (segments and frame), the heel with the Nike Air logo, the layered toe panels and the outsole. These four angles give the AI the most model-specific signals.
