Hit up whistler today and changed up my step up a little by moving to a +12 -9 with a 12 degree high-back lean forward. Didn't have any pain in my knee at all over the 4 hours i was boarding and the foot pain was fine, only thing i found was that i think i'm tightening my boots too much and my feet are getting a little numb from that, and also that instead of bending my knees to go to my toe side, was kinda standing on my tippy toes to do this. Hence putting pressure through my both my feet and making them sore. So its just a matter of working on technique. It's only my 5th day on the slopes so need to just keep the passion and get the right technique down from the beginning so i don't get some nasty habits that stick with and can't be changed.
