My shoes have safely arrived and, as I expected based on your advice, they fit perfectly. It's true that they're a bit tighter right now since they aren't triple wide, but I can feel the suede stretching already just as you predicted; triple width would probably ultimately make them too loose as the suede stretched. Thank you again for all your help and I don't know when I'll order shoes again, but when I do I will go straight to Flamencista.com.
Best value for money
Peace of mind
