The Concepts x Nike Air Max 1 SP ‘Mellow’ showcases an eclectic design inspired by music festivals from the late ‘60s.

The Boston-based retailer dresses the retro runner in blue tie-dye denim, lined in burgundy corduroy and accented with a cowhide forefoot overlay, along with different kerchief prints on the collar and heel.

Green textile on the mudguard draws inspiration from a military surplus M-65 jacket. Mismatched Swooshes feature floral and striped motifs, while the red velvet tongue displays a woven tag with dual Concepts and Nike branding.

A subtle mud-splatter print distinguishes the off-white polyurethane midsole.
