The Authentic SF combines our original low profile silhouette with the Vans Surf SF build to create an upgraded, comfortable lace-up style with a collapsible heel. Made with water-based inks and glues, the Tortoise Authentic SF also features sturdy canvas uppers with retro stripes, molded UltraCush sockliners for upgraded cushioning, Vulc Lite construction, and classic rubber waffle outsoles with single-wrap foxing tape for lightweight comfort & tortoise eyelets.
