In reply to (the OP really, but quoting) wbo:

^Regarding this..
I don't know what you have around you (your profile says W Yorks), but if you ever find yourself driving past Sheffield on the M1, these guys are only 10mins from Junction 34 and I can't recommend them highly enough:

Really know their stuff and are happy to spend lots of time with you (or leave you in peace if that's what you prefer) while you try on every shoe in the shop if necessary, and have a little run in them if needs be.
Needless to say if you do all that and they have a shoe that suits you, you're morally obliged to buy it there. Obviously, obviously I know you're not that guy who tries on all the shoes then goes home and orders them online, but people are weird so I thought it worth a mention all the same.
