The Onitsuka Tiger Men's Serrano Casual Shoes are inspired by the high-performance track spikes of the 70's. These shoes sparked the beginning of champion sport shoes. This heritage runner carries the tradition of the brand's racing customs with its streamlined silhouette, lightweight nylon upper and a spiked rubber outsole. Dual-overlay suede textures accent the toe cap and heel while a padded tongue and collar offer maximum comfort in classic varsity colors.
