These UGG suede moccasins are very light, warm, and reliable. Purchased at Isetan and stored after being worn only twice. They are in beautiful condition. As a 21cm size is hard to find, how about it if you're looking for one? Perfect for those looking for a small size, and for children too! This style is easy to incorporate into a wide range of outfits, from casual to dressy. Crafted with fluffy natural wool lining and a lightweight, flexible molded rubber outsole, these shoes can be worn both indoors and outdoors.
