I don't see the big deal. I've got narrow feet and wear a B, but the uppers still touch, and I couldn't care less. Thicker socks may give you some more spread, but I really don't see the problem. The only solution for me would be to go to slip-ons, and that ain't happenin'.
I worry that, sometime down the track, the leather will stretch and they will no longer be a nice tight fit. since I can't pull them tighter than where they meet in the middle.
