In reply to lukeypcs:
Argh, so close! I'm around 39 left foot, 38 right foot. And I have literally a bag of unused shoes because of repeatedly buying 2 pairs during sales and thus having a collection of redundant shoes. Happy to send any that are any use to you for the price of postage (I'm in Ireland though, so factor that in) - I'll pm you a list in case anything is of use.
In terms of buying split sizes, as previously mentioned, there is the EB Split. Also, Andrea Boldrini sell split sizes on some models on their website http://www.andrea-boldrini.com/en/. Butora apparently do so as well, but seem to be just in the US.
Evolv do split sizes on their US site, and their European importers http://beyondhope.co.uk/ have in the past sorted me out a split pair for £30 extra on top of the usual price - it took several months to come through though.
