Yes, they fit more like an 11, I think. I'm an 11D in Ferragamo or Allen Edmonds, and these fit more like that.
Most of my EU 44's correspond to a US 11; wouldnt a 10.5 be a 43.5?
I always notice your avatar, it's great! Ikiru was always one of my favorites...
EDITED to add: I'm going to be traveling unexpectedly due to family illness from 6/24-6/29. I'll be able to receive PMs and Emails, but I won't be able to ship the shoes until I return next week. Thanks and sorry for any inconvenience.
