Revival of the Pro B Dunk. The Pro B Dunks were introduced in the early 2000s as a fat-tongue predecessor to the skateboarding-specific Nike SB Dunk. They were a preferred Nike model for skateboarders in that era thanks to the extra padding on the tongue and interior, which provided protection when skating. Leather upper softens and gains vintage character with wear. Foam midsole offers lightweight, responsive cushioning. Air Zoom cushioning helps provide a quick-off-the-ground sensation. Rubber outsole with classic pivot circle adds durable traction and heritage style.
