A collaboration between Jordan Brand and Union LA, the Union LA x Air Jordan 4 Retro 'Guava Ice' released in 2020 as a follow-up to the brands' joint 2018 effort. Built with pink suede the upper includes mesh at the toe box, quarter panel and collar to provide breathability. The TPU wing sports a semitranslucent finish, while the lateral quarter panel includes a Union LA flag. Underfoot, the yellowed midsole houses visible Max Air in the heel for cushioning.
