FWIW - The same thing happened to me when I bought a pair of EGs at Saks. I also wore them for a day before realizing that one of the shoes was a 1/2 size small. They "found" me the second shoe in the correct size - though the inside labels were different and the color of the leather was imperceptibly different. Anyway they made the exchange - no issues and gave me $100 store credit to boot. oh please...saks and an indvidual seller are two different things.
