Air Max 90 width availability

Available in standard (D) width only.

Only the standard (D) width is offered, so very wide or very narrow feet may need to adjust length or choose a brand with more width grades.

Expert fit notes

The Air Max 90 fits slightly narrow through the midfoot and the toe box is shallower than the Air Force 1. Most wearers with a standard-to-narrow foot are fine in their usual size, but wide feet should go half a size up in the standard D width for comfort. There is no wide version, so genuinely wide feet may want a roomier silhouette.
