The Concepts x Nike SB Dunk High “When Pigs Fly” is one of the most memorable collaborations between the Boston-based sneaker boutique and Nike’s skateboarding division. Released on Black Friday 2012, the “When Pigs Fly” Dunk High features a premium pink suede upper with metallic silver Swooshes and blue and yellow accents. A hairy suede tongue in grey and a gum rubber outsole complete the impressive colorway, which was inspired by the classic comedy film Porky’s. Released in limited quantities, the Concepts x Nike SB Dunk High “When Pigs Fly” has become one of the most sought after colorways of the silhouette in recent years.
