ZiggyStarHe had a follow-up review in which he kind of backtracked on that.
"I mentioned in my ‘first impressions’ that I thought the shoes in the ROCLITE range sized a 1/2 size too small. Now I am not sure? Sorry for being indecisive but I have run in them for 1-month and I have been very happy, I must stress though that I used a thinner sock than normal."

I bought my same typical Inov-8 size of 11 (I almost always wear a 10.5, occasionally an 11).
ZiggyStarI love innov-8 shoes, but I have had trouble with the sizing. See the photo - the two shoes are supposed to be the same size, but the X-talon is a bit small for me, whole the other is perfect. And notice the cm measurement is different! I usually fit EU size 44, so the X-talons are at least half a size small, maybe more. It's great that innov-8 do make their shoes in half size steps, but to take advantage of it you really need to try them on, since they vary from model to model.
