I just recently purchased a pair of used boots, and when I was up skiing I felt like my knee were very knock knee, they almost touched but it was affecting my stance, which way do I adjust the cant to fix this?
I think you will soon become aware that there is much more to this alignment "stuff" than could possibly be covered in a single simple solution to such a question. You will have to supply some additional info. Do you have footbeds is the first thing? Would you be able to supply video of your skiing? How about indoor still photos? Looking forward to hearing more from you.
and even how much too big the boots are on you. if your foot/leg/ankle is rattling around, no amount of can'ting will help that...
read the wiki's and see if that helps, or at least gives you some more info to give to use.
