I like a wide shoe, so these were made to be 10.5 E. In a normal running shoe, I wear an 11 EE. From what I was told most running shoes (made overseas)claim a EE but are really an E so that's what I went with. These stretch a bit and mold to your foot, hence a 10.5 and not an 11.
I didn't trace my foot. I asked about that and was told there was no need based on what I was ordering.
I don't wear socks much with my canoe mocs, but always do with my lace boots. Yes, they'll bleed a little at first.
