The WB-71 collection was released in 2000 and is definitely one of Nike’s most slept-on lines—I haven’t seen anyone mention it before. Nike introduced both a WB-71 line for women and an MB-71 line for men. The “71” most likely refers to the first year the Swoosh was used, while “M” and “W” indicate the intended gender. The “B” stands for body.
