Say Hello to Jolly Thermo! We've taken everything you love about Jolly and added serious cold weather protection! A warm lining and temperature-regulating insole keep toes warm. A cuff and drawstring keep rain, snow, and debris from getting in! This style has a standard fit, and the entire boot is made from natural rubber, with reinforced toe caps and a nonmarking sole. All Viking rubber boots are handmade from natural rubber. These boots are PVC-free and vegan!
