The Adidas Kids' Terryx Conrax CP Winter Boot wraps waterproof tech and hardcore insulation into a kid sized package. This boot might be a bit smaller than its adult size counterpart, but it is tough enough to handle high mountain winters, cold weather hiking, and even a bit of alpine exploring. ClimaProof membrane seals out heavy precipitation and wicks moisture for a dry, comfortable feeling, and Adidas' drainage system uses perforations inside the midsole to ditch water if he steps in a puddle those perforations also help reduce total weight. A generous layer of PrimaLoft insulation traps heat around his foot so even in freezing temperatures, he'll stay warm, and the aggressive Traxion rubber sole keeps him firmly gripped to icy, snowy sidewalks and trails. Semi auto crampon compatibility means he can strap into a set of feet teeth for exploring glaciers or even for learning how to maneuver with crampons on his feet.
