Biker style boots by UGG ® Australia with functional buckle detail and 100% waterproof upper and seam sealed construction. Featuring Vildona® insoles which provide thermal reflection of heat & cold. They prevent heat loss in the cold and minimize heat accumulation in warm temperatures. 100% Authentic UGG® Australia boots Rich gull-grain waterproof leather upper 10 1/2" shaft height Soft sheepskin lining for lots of warmth Vildona® insole reflects body heat back inside for extra warmth Adjustable buckles across ankle and cuff EVA molded sole is light and flexible ***Loved and used, but they still have good life left in them! These fit a tad tight on me, so someone with a size 8 or 8.5 foot may like these better.***
