The Nike SB Dunk Low NBA Deep Royal Blue is part of Nike's SB (skateboarding) line. The design is inspired by the National Basketball Association (NBA) and features the Swoosh logo on both sides along with the embroidered Nike logo on the heel. Designed specifically for skateboarding, it has a low-top silhouette for ankle mobility. The padded collar and cushioned insole provide comfort and support, reducing foot fatigue and injuries. The durable rubber outsole has a herringbone pattern for traction on various surfaces, ideal for skateboarders. The standout feature of the shoe is its Deep Royal Blue colorway, released on October 13th, 2018 at a retail price of $110. The Dunk Low SB also revisits its basketball roots through a collaboration with the NBA, featuring a satin upper in Deep Royal Blue inspired by 80s NBA team jackets. The purple midsole includes a concealed Zoom Air unit for enhanced skate performance, with dual Nike SB/NBA branding on the custom sockliner and tongue.
