The crocs have size M 10 and W 12 embossed on the bottom. The paper work says otherwise, I would trust what is on the bottom of the shoes. No scuff marks, bottoms show they may have been walked in to test fit. Failure to return them in the time given was not done, so now’s your chance at a fair price. Please see photos for condition description. Thanks for looking, questions welcomed. No returns for this item.
