Introducing the new Tufs collection. Modeled after the Kids Ankle Deck Boot, this new style is a one-piece injection molded boot made entirely from BioLite. This is an eco-friendlier Eva compound found on other popular Xtratuf styles like the Adb Sport, Apres Fish Slides, Riptide and Sharkbyte 2. 0. The Tufs are lightweight, flexible, 100% waterproof and still non-marking and slip resistant like other Xtratuf footwear. On the inside, they have built in ridges at the front and back for easy grip when pulling them on and have a textured footbed for added traction and a secure fit. Launching with five color options in child and youth sizing, the Tufs collection is built for young explorers..
