Originally designed as running shoes, the Nike Air Max 90 Iron Grey sticks to its roots with the Waffle sole, a textile/leather upper, and classic TPU details. The Nike Air Max 90 Iron Grey features a textile upper with leather and synthetic overlays. Most of the sneaker is in iron grey, with the Swooshes appearing in white on the lateral and medial sides. The low top also includes a padded tongue and collar for maximum comfort, and underfoot, Max Air cushioning provides cushioning, while the Waffle sole adds traction and durability. The Nike Air Max 90 Iron Grey was released in January 2020 and retailed for $120.
