Since I only get 5-10 ski days a year I have to compensate by whipping out the old:

If not I just wanted to advocate and encourage you guys to try it for your skiing fix, it helps greatly with inside foot tipping + management ( particularly if youre doing a double push (http://www.nettracing.com/step1.htm)). And definitely has a lot of shared technique with PMTS, keeping upperbody stabilized, and drastic tipping of inside foot on outside edge. Don't forget doing awesome Slalom turns downhill !
Note how speed skates have a low ankle cuff to allow for extreme pro/suppination of the ankles.
Maybe a more experienced PMTS'er can draw some similarities between skiing/skating
