I, too, have just stupid-wide feet (due to bunions), and have had much of the same problems you are experiencing. In a pinch, I had to pick up a new pair of shoes over in Leavenworth, and got a pair of La Sportiva Focus'. As I understand it, they aren't typically made for wide feet, but these fit and climb great. Five Tens run wide, but will probably stretch on you. Good luck.
