Your feet are only 1 size larger then mine and my boards waists are usually 265ish and I'm fine
Boards are rated based upon your weight and the type of riding your going to do. I would say a mid 160's is going to be good for you as an all mountain board. Maybe even slightly closer to 170.
Low 160s would be a park board for you
And obviously make sure you get a wide board
