That was actually very helpful, thank you!I have a pair of Lloret derby boot in shell. This pair is UK8 and fits me pretty well with thicker socks.
I am usually in between UK7.5 & UK8 and I have the following Carmina lasts/sizes
- Rain UK 7.5 wholecut chelsea in museum calf - fits well with thin socks
- Simpson UK 8 penny loafer in suede - very tight (comfortably) fitting with medium thickness socks
- Simpson UK 8.5 unlined chukka in shell - generally too loose all around with thick socks - definitely need insole but I feel the last just doesn't work for me
- Lloret UK8 derby boot in shell - roomy fitting with medium thickness socks
I heard shell boots are usually larger than calf boots in the same size as they are not lasted as tightly as the calf ones.
Hope this helps!
