The UGG Ultra Tall woman's boot is made with 100% premium twin-faced sheepskin that wicks moisture away from your feet. The lugged outsole and removable insole is great for both comfort and function. The heritage UGG Australia Tasman woven tape on the back of the boot adds a little something special to this tall boot. This boot is available in black, chestnut (dark tan), chocolate (brown), and sand (tan).
