We must have clone feet. My real size is 10 or 10.5 but I'm often lucky if I can find an 11 that is wide enough. The only place I've found that reliably stocks wide shoes is Nordstroms. They have great service and high quality shoes but you'll pay for it.

For something cheaper I sometimes have luck at DSW (Discount Shoe Warehouse). I don't know if they are a national chain or not. Sometimes I get lucky and find a wide model in my size or at least they have enough selection that I find something I like that is comfortable.

For casual shoes, my brand of choice is Merrell. They usually fit well even in standard width.
