Hi, br> I wear a 9B for AE dress shoes (Walton, Macneil, Delray, Brentwood (3 last like Walton)). The AE shoe tree size chart indicates small but 9.5B and 9C are both medium. Does it make sense to size up? Also, I've read a bit about the full toe vs split toe, but don't see a clear trend in preference. They say that the full toe is specially made for AE shoes, but with the lasts being so different, I don't understand how that can be true. So, which makes more sense here? Is there any reason to get AE trees in particular for AE shoes?
