quick question before I have to run out. What do you girls do about sizing differences when you wear CL's with stockings during cooler temps and without stockings during warmer temps. I just got back and wore my leopard NP's, without stockings to a lecture this morning and my feet are killing me. It was warm and humid so I think so of it is swelling, but I have red marks in certain areas along my toes. I also wore them on Thurs. with stockings, walking all over and they were fine, except the strap kept slipping on one shoe. So how do you buy one size and wear it all year round?
