Welcome, also 53 and heading for my 10th season. A 144 is a good size and would encourage you to go for an intermediate to advance board since you are an advancing skill wise and want performance responsive board. Do not get a beginner board like the feather, you want some thing that is perhaps be beyond your current level so that you can ride in to it. I'm a fan of c2btx design. a good compromise between camber and rocker...something like a gnu b-nice. Btw with small feet pay attention to the board width...you'll want something on the narrower side and medium flex to med stiff flex.
