Waterproof. Winterproof. Our always-sells-out Thermal series now encompasses Original series Women’s Hi Top boots. Blundstone #2223 in Rustic Brown is a warm twist on one of our more popular leathers. Improves with age! Hi Tops rise slightly higher against the elements, and now add the heat-retaining qualities of pure wool footbeds and Thinsulate™ lining for a boot that makes everyday sense. 100% waterproof, even the elastics. All-day Blundstone comfort and warm feet, come what may.
