Of course, if the Park Avenues hurt your feet, are you sure you're wearing the correct size Park Avenues? Maybe, because of the characteristics of the AE Park Avenue's last or something, you simply need to size up half a size in length, or a letter or two in width, for the Park Avenues to fit you comfortably. Just as it's not uncommon for a man to wear, say, a regular length jacket in one line, but need to buy a long length in another, so may you wear, for example, a size 10D shoe in some lines, but a size 10E or even 10.5E, in others.
(I'll add parenthetically that feet can - and often do - change in size and shape over the years. Yet most men figure that if their shoe size was, say, a 10D when they "stopped growing" at age 17, it's still a 10D now, when they're 20 years older. Many men go decades without having their shoe size measured on a Brannock device. I'm not saying that all men act this way, just that lots do. And I can tell you from personal experience that even a single letter difference in shoe width can be the difference between comfortable feet, and sore, aching feet. And that this is especially true with dress shoes - for various reasons, sneakers, moccasins, "casual shoes," etc., are often more forgiving of such things. I wonder whether this isn't one reason why so many men claim to find dress shoes uncomfortable.)
