I bought 4 pairs a few months back and haven't worn them out of the house because they hurt my feet. I got the Stingrays and have had these problems: (a) the back elastic digs in causing redness, (b) the front elastic near the medallion digs in, and (c) both side elastics dig in and hurt my feet (my feet are a bit wide). I've tried stretching them with a shoe stretcher but that hasn't helped much. I also tried walking around the house with socks on but again, that was not much help. Please, if anyone has any advice, do share! I would hate to return these because they are so pretty. TIA!!!
