So I learned how to ski last winter and fell in love with it. My parents decided that if I go skiing often over the next two years, it would be cheaper to buy me skis than for me to constantly rent them. Needless to say, I'm pumped. When I went skiing with them today for the first time, I had them waxed. How often does this need to be done? Do I have to get this done a few times a season? I got them waxed at the ski resort, but is it possible for me to do this at home?
