PLEASE NOTE: Print Patterns May Vary. In collaboration with Boston-based boutique Concepts, the Nike Air Max 1 SP Concepts Mellow pays homage to '60s and '70s youth culture with its fabrication and palette. It is constructed with a medley of bleached denim, ripstop canvas, red velour, and bandana materials, each contrasting one another. The embroidered 'flower power' Swoosh nods to common clothing design themes of the 1970s. At the base, a speckled Air Max sole completes the design. 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.
