I have a pair of 09 Reliks and they fit the same as my Nikes. Having tried on boots from more current years, my opinion is that they still fit true to size. But try going to a boat show and trying on a pair before you buy them.
I wear a size 9 shoe and my 2012 Ones are size 9. They will be snug because the liners are a little thicker than previous years, but they will form to your foot and break in just fine. I would go with a 10.
If you want I have a used pair of 2012 ones if you are interested, size 10. I loved em but went back to open toe bindings. I wear size 10-10.5 shoes and these fit snug but great.
