The Concepts x Nike Air Max 1 SP 'Heavy' pays homage to the counterculture movement of the late 1960s, showcasing a mixed-material upper that draws inspiration from that era. The sneaker features a striking blue tie-dye denim upper, complemented by a cowhide forefoot overlay that references the Woodstock music festival held at Bethel, New York. Embracing the fashion trends of the time, the interior is lined with brown corduroy, while a tiger camo print adds a touch of flair to the mudguard, and various bandana prints adorn the collar and heel overlay. The woven tongue tags proudly display both Nike and Concepts branding, adding a unique touch. The Swooshes on the sneaker are intentionally mismatched, with one featuring floral designs and the other showcasing stripes. The midsole boasts a distinctive mud splatter graphic, drawing inspiration from a concert in the park. Overall, the Concepts x Nike Air Max 1 SP 'Heavy' captures the essence of the late '60s counterculture with its eclectic mix of materials and intricate detailing.
