I just called and spoke to Devin at the front desk and he said that if the pair that I am interested in doesn't fit, then I can return them (unworn of course) and have the total returned to my card or exchange if the size I want becomes available. I asked even on the sale item? and he said yes.
I think it would be best just to call yourself and confirm just to be on the safe side .
Perfect thank you so much! That's what they said when I ordered too. They're wonderful :)
