I just bought a pair of Sebagos in a 10.5. They hurt the hell out of my feet; I wore them last night and my left foot is blistererd beyond belief. The fit seems ok, a little snug, but probably fine for shoes worn without socks. How long will it take for the leather to soften up? Should I wear them with socks a few times just to break them in? How do you guys go about breaking in new boat shoes?
