The Union LA x Air Jordan 1 Retro High NRG 'Black Toe' sees the venerable Los Angeles retailer take inspiration from thrifting and DIY culture to create a new take on the sneaker that started it all. In addition to a pre-yellowed midsole for a vintage aesthetic, a mismatched collar is attached to the rest of the upper with zigzag stitching that gives the impression of a makeshift design.
