“These run large for me. I usually wear a 10 in sneakers so I sized down to a 9.5 which was still extremely large. So I ordered an 8.5 and a 9 to see which fits best. The 8.5 fits great with the length of my foot. I have extremely narrow feet so there is a gap at my ankle. I am going to try to shrink this part or add some elastic thread to see if they will fit better around my ankles.”
