I absolutely love these slippers! They are so comfortable and warm, I live in AK where the winters are cold.  These keep me cozy and warm.  I would definetely order a size down.  I wear an 8, and got the 6.5-7.5 and they fit perfectly.  I ordered a pair for my husband, my 5 year old daughter and my 4 year old son.  They love their slippers as well!
