I'm an 11D heel to toe, but 11.5C heel to ball. I tried an 11D in a different leather, but it was definitely too snug in the toes, so definitely be sure of your sizing - true to size is right, I think, but I also think they're a touch on the narrow side as the 11.5D works well for me. That said, they're well-made and quite comfortable. Can't complain at all once you get sizing down right!
