Daytona Boot Sizes

[Graemsay]

I'm rather attached to my ankles, and am thinking about getting a pair of Daytona Safety or Security boots. They seem to be popular round hrets, and I've got a couple of questions:

1. I've heard that they run a bit small compared to their advertised size, and that you should go up one size. Can anyone confirm this?
2. What are they like for walking in?
3. How well do they wear?

Thanks,

Graeme
