The word on the street is that these are the next 420 weed-inspired edition of the Nike SB Dunk for the now annual April release, but we’re having trouble figuring out exactly what the inspiration is at this point. With an acid-wash marbled blue upper, subtle rasta stripes at the heel, and graphic insoles that appear to feature a buckle, our best guess is that this unique edition of the Dunk Low is inspired by hippie backpacks, an essential carrying device for your bong and hacky sack. Speaking of hacky sacks, last year’s 420 celebration from Nike SB featured a whole set of hacky sack inspired sneakers, so perhaps we’ll see other models on the horizon with a coinciding look to these mysterious Dunks. Another idea floating around about the colorway is that it mimics smoke in a water bong. Get a good look at them here and let us know if you can deduce any specific colorway inspiration. Then be on the look out for them soon at select Nike SB retailers right around the pothead holiday.
