Concepts unleashes their trio of Nike SB “Grail” collaborations tomorrow, July 25th. The ambition teaming up sees the Boston-based boutique take inspiration from the endless hunt for the most sought-after relics in the world. Stained glass motifs land on the crazy-printed Nike SB Dunk High featuring a transparent ankle support in an homage to intricately colored window art. The Nike SB Dunk Low utilizes an iridescent upper, mismatched tongues, and golden skulls. The Nike SB Janoski Max has a multi-colored upper that will eventually wear down to reveal the clean white suede beneath the surface. And if you’re in the hunt for the entire trio, we’ve teamed up with Concepts for the #CNCPTSSNGRAIL Giveaway which you can enter on Instagram right now before the winner is chosen later today.
