Size is perfect. There's not really a LEFT or RIGHT foot. The faux fur is dyed, so not knowing this, I wore the slippers and then walked around with dye stains on my feet for a few days. This will be my 4th pair of Quoddy shoes. My first pair was a custom order because I really want to buy American made products. Not sure the price equals the value of their foreign shoes. Regarding more detail on fit: I am a woman with wide feet. I bought next size up since I am a half size, and purchased the men's because men's shoes are usually wider. The actual fit part is perfect. My previous purchase was a sandal and I am not very happy with those either. I have mules coming, and I hope to be able to post a better review.
