Allen Edmonds: 10D
I measure 10E according to the local shoe store.
These look and feel great so far. The foot bed is really comfortable already. There's no heel slippage or discomfort around there, the ankles, or the toes. The only pain is around the top, but I think that's just because I haven't worn any 6" boots in several years.
I'm not sure I understand the big sizing down and hard break-in trend. I would rather them fit right from the start. I wear thin socks and tie them fairly loose for a few days when new (even though I like my shoes pretty tight) and then gradually start tying them tighter and wearing thicker socks as they break-in.
