Also, to get better help from your fellow riders who live in the States it looks like your US measurements are about 5'9" and 165lbs (if my quick math is right)........with that size 9 boot you are definitely correct in that you have no need for a wider board, you could use one if you want (powder days) but it'll make turns (and eventually tricks when you get there) a little harder then if you had a normal width board. I personally rock a size 12 boot so I'm stuck with only riding 26.0+ boards and all my boards are wides from a 26.1 to a 27.2
Now as far as board length goes, I'd say something btwn a 153-156 would fit your riding style and weight the best.
Keep it longer if you are really only looking to free ride and not trying to hit boxes/rails.
Something like a 154 Skate Banana with a waist of 25.3 should be right in your money zone.
Good Luck with the search bro.
