2012 Parks Binding Sizing

Have never run Ronix bindings. Wondering if they're true to size. Specifically the 2012 Parks boot.

Currently running systems with Kobalt boots. I generally wear an 11-11.5 shoe depending on the brand. I found the kobalts ran small so I've got the 12/13's and they fit perfect.

Prior to the systems, I was running 08 SL PB Floyds in an 11 and they fit great.

Thanks for any input.
