In 2001, Nike expanded their brand with the Pro B line of Dunk Lows, the precursor to the SB Dunk series, their first foray into the skate shoe market. The Dunk Low Pro B 'Plum' sneaker was one of the first sneakers introduced under the newly created line as part of the three-shoe ugly duckling pack that was released exclusively in Japan as part of the CO.JP collection. This version features suede overlays with a hint of mesh, supported by wide, OG-inspired laces.
