Scarpa Mescalito boots are made in half sizes, as most Scarpa boots are and have been for years. The half sizes seem not to be imported into the UK, though...

Check Ellis Bringham.. 
I found my Mescalito TRK GTX there in UK 10.5...

and I really like them.. super comfy, great for most things... scrambling, paths, tracks... 
good fit for my feet with a fairly wide toe box, but a fairly locked in heel to allow miles without the blisters!!

I think they sell them in full euro sizes only, or at least used to, so you will get 10.5 (45) but won't get size 10 (44.5). 

ah - gotcha... 
Thats annoying..
