I buy these shoes 1-1.5 sizes bigger because they fit snugly. I bought this shoe to wear as a slipper. I've tried all kinds of slippers and boots to keep my feet warm in winter, but nothing beats the support of real shoes. The fluffy inside is incredibly warm. I can't imagine wearing it like a real outdoor show. All other slippers or boots are practically not supported. These are ridiculously overpriced slippers but I've had them for years, they're incredibly comfortable and now my husband finally broke down and asked for a pair. They are not very easy to find and people always ask for them.
