Thanks MSSneaker and Whatever123! I got a size UK10 on the Coggles website and the box says they are 11E which is the same size I was able to try on in the Ghille Hunt boot. I tried them on here in a Toronto store while wearing thick sport socks and the fit was spot on. A little snug but from what I read on the Yuketen threads that is how it should feel when brand new and I plan to wear with thicker thermal type socks with these boots. I usually wear a size 44 in CP's, 11US in Red Wings, 11US in Vans, UK10 Lanvin, 44 NDC boat shoe, 11 US Clark Wallabee's. Not sure how to measure my foot but: from heel to end of big toe = 10" (approx 27cm) width (widest part of foot) = 4.5" (approx 11.5 cm) I hope that helps a bit and gives people a bit of a reference for those wanting to purchase these amazing boots.
