I switched my cart from 2 pair to 4 pair to take advantage of the better pricing. Unfortunately when I did that it reverted the size back to a 6 and I didn't catch it. I asked the company if I could return the 4 pair of size 6 for my true size and was told to keep & donate them, no need to return, just share them with someone else. They sent me the correct size for only $20 toward shipping. How fantastic is that???!!!!
