I didn't realize size 11's were as hit and miss as they sound to you, hamster! I wear a size 10. And rarely, do I have trouble finding them. One time, last year I went to Lord and Taylor, and found this must have, for me, pair of Michael Kors shoes. They didn't have the color, I wanted, in the style I wanted. So I tried on the other color, and they gave me a special order that shipped directly to my home, at no additional charge, and they even rang up the sale price(s).

I found this shoe store, review of top 10, with return policies included. Hope that helps!
