Kelsey Plum and Sabrina Ionescu just exposed a wild WNBA rule: unless you have a big-money shoe deal, you basically HAVE to wear Nikes on the court. Even if you’re signed with another brand, you can’t switch midseason like NBA players do. Plum wanted to hook up her rookie teammate with Under Armour kicks but couldn’t because of this rule. Fans are calling it out—shouldn’t players get to rock whatever brand they want? #WNBA #SneakerNews #Nike #Spirituality
