Note: I'm normally a size 9
Last season I had a pair of Nike Lunar Dominate (size 9), which split after one or two matches. After a refund I then replaced them with a pair of Adidas 2014 Adipower Vector. I brought the Adidas in a size 10, due to the US/UK sizing. I found them to be slightly too big and wished that a 9.5 had been available (they were out of stock everywhere). They also don't look as good in the flesh (i.e. close up), as they're very plastic looking IMO.
I also tried some New Balance CK4020 Turf and found the size 9.5 were too narrow.
Because of my poor fitting Adidas, I've picked up a pair of Asics Gel Advance 5 in the PD sale (size 9.5). I haven't worn them in a game yet, but they're very light and comfy.
My advice would be that Adidas and New Balance sizes are a bit on the small size. Also that Asics and New Balance are on the narrow side.
