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.
