Gents, I'm sorry if this has been mentioned already back in the thread, but I thought that I'd ask: Carmina makes balmoral boots in two lasts, Robert and Forest (as far as I am aware). I have a high instep, and I've been told that the Robert last would fit my high instep in a balmoral boot better than the Forest last. I take a UK9 in the Rain last, and it fits my instep very well. Would anyone happen to know if I would take the same size in the Robert last? Or, should I vary my fitting by half-a-size? Any advice will be gratefully received.
