Vik100,
I bought new boots about 6 months ago, and I also wondered about the half size issue. Apparently it is true that they don't make the outer part of the boot, the shell, in half sizes and it's only the liner that makes the difference.
I wrote a full report on my boot fitting experience here:

Best of luck with getting nice comfy new boots
Oh, and if anyone is interested, my toe-nail seems to have grown back okay but it hasn't quite reached the point where it needs to be trimmed, 6 months after I broke my toe.
