Released as part of the renowned retailer's 30th anniversary festivities, the Union LA x Air Jordan 4 Retro 'Desert Moss' brings back the creative partners' modified AJ4 from 2020. This pair is taken from a capsule called 'Tent and Trail ', with colors and materials inspired by '80s and '90s outdoor gear. The mid top features an upper constructed from a mix of bright purple mesh and mustard yellow suede. Vibrant bursts of turquoise land on the lower molded eyelets and heel tab, marked with Nike Air branding in a lavender hue. A stitched fold-over tongue, yellow 'UN/LA' tag, and translucent TPU wings carry over from the 2020 release. The shoe is mounted on an off-white polyurethane midsole with an aqua-tinted Air-Sole unit under the heel. .
