Boston store Concepts and Nike SB teamed up in 2015 to bring a newly themed collaboration to the sneaker world, the "The Holy Grail Pack." Departing from the "Lobster" theme made famous by the New England boutique, the design team focused on three SB silhouettes, each sold in limited quantities and accompanied by special boxes and accessories.

This pair features an iridescent upper, metallic silver quilted lining and custom gold skull lace locks, which elevate the pair and instantly separate them from other SB models in the pack. The right shoe comes with a bright red tongue while the left is a deep blue, adding to the playful colors of the upper.
