no problem! they're on perrins court just opposite of villa bianca..
i was going to have mine re-soled in helsinki and i specified that i wanted a light sole, not black (mine are tan) and the guy pulled out this outrageously thick sole and said that's the thinnest they had i swear it must have been a cm thick so i said i'd take them elsewhere..
oooh and there's another place, it's called something like half moon shoe repairs, it's on half moon street off piccadilly. they're good as well. and classic shoes (i think it's in camden, jimmy choo use them for their repairs) are good too from what i hear but i haven't used them.
I just called Perrins and he didn't sound too horrified which is better than the reaction my local shoe repair place gave me!
Sounds like your cobbler tried to put on the same one my did.......I nearly died!!
