Actually, checking the size of my other shoes then I reckon the NB would be a touch on the small size (unless they come up big).
Tend to be 10-10.5UK / EU45 in Nike Pegasus or Adidas Adizero
I'm a 44/US 10 in Adizero Adios; I'd say the NB are true to size - the cm measurement is 28 if that helps. They're almost a racing flat so should be a snug fit anyway. Your call, if you want them you're more than welcome.
Sure, why not: PM me your address and we'll take it from there
