As a general rule, I like Jones Bootmakers — their shoes are midlevel in terms of quality, and if you go during the sale seasons you can get a pretty nice pair of leather shoes suitable for office wear for about £50. This particular Jones seems to be very limited in its selection though, as it’s a much smaller store than some of the other locations. If you’re in a rush and are willing to pay full price you’ll probably find what you’re looking for, but if you’re looking for something specific(or a deal!) you’ll probably want to try somewhere else.
