In reply to Soapy:
About 60% of people have different sized feet, and of those 80% have a larger left foot, so there should be plenty of matches out there for you. Alternatively, I have a larger left foot and a few years ago I found out that Evolv will supply split size shoes, so I contacted the U.K. importer
http://beyondhope.co.uk/our-brands/evolv/ and they added my request to their next order from The States, it took a couple of weeks to arrive and cost a bit more though.
