Whatever board you consider, look at the specifications/details of the board. There should be listed a weight range, generally you want to fall in the middle of the weight range; some of it can be mitigated by flex; and with small feet you will want to pay attention to waist width or width at the bindings. You should throw out some boards you are considering, your experience level and where you will be riding....snow/terrain is also part of the equation. Wiredsport, BA and others can help once you know what you want and your ability level. Narrow it down and if you can go and demo or do a performance rental to test drive them.
