Nike SB Heritage Vulc Shoes. Built from suede and canvas, the Nike SB Heritage Vulc pays homage to classic skate shoes. The modern design combines foam cushioning and flexible rubber for performance you can count on. Suede and canvas add classic style and durable performance. Exposed foam on the tongue creates a vintage skate vibe. Gum rubber has been thinned out in key areas for a lightweight, broken-in feel right out of the box. Vulcanized construction fuses the outsole to the upper for a flexible, broken-in feel. Foam sockliner. Imported.
