Modeled after the Kids Ankle Deck Boot, TUFS are 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. 100% Waterproof BioLite - eco-friendlier high performance EVA Care Instructions: Shrinkage and warping may occur if exposed to high heat or cold temperatures.
