The upper of the Nike Dunk LowThe Concepts x Nike Air Max 1 SP "Mellow" features a unique design that was influenced by late 1960s music festivals. The Boston-based retailer adorns the vintage runner with burgundy corduroy lined blue tie-dye denim that is accentuated with a cowhide forefoot overlay, as well as various kerchief designs on the heel and collar. The green mudguard material is modeled off an M-65 jacket that was surplus to the military. While the red velvet tongue showcases a woven tag with dual Concepts and Nike branding, the mismatched Swooshes are decorated with flowery and striped patterns. The off-white polyurethane midsole is distinguished by a faint mud-splatter print. Valentine's Day is all white and has tumbled leather and patent leather blocking. The patched yellow heart on the back uppers of the limited-edition shoe adds a pop of color, symbolizing friendship and happiness. The tongue and heel are adorned with yellow Nike logo.
