O.K. got my wife a new sled this year, I need to get her a new pair of boots,she not that much of a aggresive rider so sweat is not a factor. I suggested a snow board type boot. She does'nt want a boot that goes so far up her leg. So I'm looking for a boot that is low cut and warm, after all the warmer she is, the longer I get to ride. Any ideas guy's? Ladies?
