Ugg Women’s Ultimate Short is introduced in 2008. It is a sleek yet rugged alternative to the Classic with top-of-the-line cold weather enhancements. Designed for comfort, durability and years of wear, the Ultimate Short is made from Genuine Grade-A sheepskin. Sheepskin has the ability to keep your feet warm and dry all day long. Different from UGG Classic Short , it has a narrower cut, a wide reinforced back seam and streamlined toe and heel protectors all for a more tailored look. Removable and replaceable comfort system insole is made of sheepskin, latex and foam for “ultra” comfort with a Mylar sockliner for warmth. Finished with EVA rubber molder outsole, it provides traction and extra comfort for all steps. It is a must-have bag in your Ugg Boots Collection.
