Brand New "Deadstock" Designed in collaboration with the mental-health initiative founded by Scottish skater John Rattray, the Why So Sad? × Nike Dunk Low SB 'The Predatory Bird' features a design theme centered around positivity and wellness. The low-top sports a light blue leather upper with navy suede overlays and a wear-away Swoosh that fades from Coastal Blue to Speed Yellow. An embroidered graphic depicting the Predatory Bird mascot appears on the lateral heel, while a yellow question mark adorns the red suede heel tab. 'Why So Sad?' is inscribed on the interior tongue tag. Underfoot, a translucent rubber outsole yields grippy traction.
