january, i suffered from extremely cold feet for years. painful. i bought a heated mattress pad and turned it out before i took a warm foot bath and put warm socks on...........it helps ALOT....somehow the warmth from beneath really does keep you warm. they are cheap. and they have a thermostat setting thing.

i also was given one of those cheap, heated foot massagers and i would use it at bedtime. the circulation really improved........good luck, pat
