"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. The TUFS collection is built for young explorers."
