The Union LA x Air Jordan 4 Retro 'Taupe Haze' is a collaboration between Jordan Brand and influential retailer Union, marking Union's 30th anniversary. This mid-top sneaker, featuring the same reimagined design introduced in 2020, is exclusively available at Union and is part of their 'Tent and Trail' capsule collection, which takes inspiration from outdoor gear of the '80s and '90s. The upper of the shoe is made from a combination of breathable mesh and soft suede in a neutral taupe color. The lower molded eyelets and heel tab stand out with bright hits of Roma Green and a raised Nike Air logo in Blue Fury. The collar lining and stitched fold-down tongue also feature the vibrant Roma Green, as well as translucent TPU wings and a yellow 'UN/LA' tag, which are carryovers from the previous collaboration. The shoe offers lightweight cushioning with its off-white polyurethane midsole and aqua-tinged Air-sole unit in the heel.
