This UGG slipper can also be worn as a shoe, but make sure you order the next size up. It's not just small for its size because of the lush & fluffy lamb-fur insert -  but even when I took out the insert, the 11 (women's) was too narrow and small in the front-foot area. UGG does offer a size 12 in this style (the Ansley), so I think UGG anticipated this issue since most shoes aren't offered in a women's size 12. But last I heard, this particular Amazon Marketplace company, WhatSheBuys (WSB), doesn't carry the 12.  What WSBs does provide is a Return Policy that's not only over wrought & old-fashioned(?), it has so many steps you end up wanting to pull your hair out (or theirs). Yet its CS reps are courteous. Still, I just don't appreciate needing to contact a company to ask "permission" to make a return of a pair of too-small shoes. WSBs overly careful policies may backfire, resulting in fewer returns . . . of customers.  (A perfect example of 'scarcity' thinking's results.
