Just to give a little background, I am an advanced skier but haven't had the money to buy new equipment in a long time. Just got a new pair of skis, so my wallet is a little empty right now. However, I am still using Salomon Performa ski boots and I think it is time for a stiffer boot. My uncle has an extra pair of Tecnica Icon Carbon boots that he said I can have. The only problem is that his liner has molded over time to the shape of his foot, so it is not as comfortable as my old boot. Would it be a bad idea to use the thermafit liner from my Salomon's in the Tecnica's?
Thanks in advance.
