I was trying on the boots today and I came to the conclusion that the sizes are pretty accurate. I am a size 9.5 and a 9 goes in good but my toe touches in the front and its a little snug. They feel fine up until I start walking, they don't hurt but I can imagine being in them for long periods of time can get annoying. The 10's fit me more comfortable.
If you went a size down because of the .5 I think its better to go up to the next size.
