The Concepts x Nike Air Max 1 SP TD ‘Heavy’ features an eclectic design inspired by the expressive festival fashion of the late ‘60s. The Boston-based retailer dresses the scaled-down build in blue tie-dye denim with a tiger camo mudguard and bandana-print heel overlay. Stitched atop the quarter panel, mismatched Swooshes are filled in with multicolor florals and stripes. The outdoor concert theme is finalized with a mud splattered midsole, enhanced with visible Air-sole cushioning and supported by a tan rubber outsole.
