Well, I can see they are Loake.
The question - which I thought would be obvious - is more about what line they are and, by extension, where they might have been made?
ImTheGroom, you are correct about them not being ideal for business in London, which is why I asked how casual people would think you could go with them. Furthermore, chinos were exactly what I was considering - although, I am also not quite sure that would work.
More opinions would, however, be appreciated.
Where did you see them? Loake has several lines, the 1880 being Goodyear welter made in England and some cheaper glued corrected grain crap, made in India. These look Goodyear welted , but leather looks a bit plastic, hard to tell from the pic.
I think you can get away with them because of the dark color in London business setting unless it's law. I wear similar brown hues I finance, and although not common, at least 10% wear brown shoes, especially non brits.
I would avoid them with chinos, a dark burgundy Oxford is a bit too formal to work with casual tan chinos. Grey flannel is a better choice with them.
