These are UGG brand sheepskin boots. The size is about 14cm, but the sheepskin is very thick and warm, so please consider a size around 13cm. For children with wider feet, an even smaller size may be suitable. Please purchase with some room for comfort. Returns due to incorrect sizing after purchase are not accepted. Therefore, these are being offered at a bargain price. No pets, no smokers. Will ship by the next day.
