In reply to Toby M:
I'm a 10.5 UK size in street shoes (EU 45)
The shoes are 43 (=9!!!) *BUT*
a) The shop (Urban rock) thought I should be int he next size down (42). Probably they'r eright if I was climbing in the 8's, but for mid grade puntering I see no need to kill my feet and I can wear these all day
b) They did stretch a little - maybe half a size
c) I tried on 2 pairs of 43s and one was noticeably smaller than the other (so I'd never buy over the net)
As for other boots I've had EBs (yes, super grattons) which were overtight at 44 (I think), some Fires which started off small but stretched miles (to the point that when the toes wore through I switched the feet), some 5.10s which fitted well but the rubber went in no time, a series of Ballets/Aces (44) and, recenty, some Boreal lace ups (with no marque logo or size on them now, but purple sides?) that I never really got on with.
For me it is about width across the toes - most shoes I've tried have either been excruciating across the toes or left a air gap at the big toe. The Katanas just seem to fit the profile of my toe length and width. They're also not a killer on the achilles, which is nice.
