They were uncomfortable. I have a pair of AE Daltons in 10.5 that were what I'd call snug and they have broken in very well.
The Thursdays Captains in size 10 would never have loosened up enough to be comfortable.
I'll probably try the 10.5 in the chukka. Just giving the shoe buying a slight break so I don't generate any ummm unwanted comments from the wife.
