and I'll have to renew my passport.
I've have played with a couple things in my "Laboratory" (the kids call it that because I Frankenstien things back to life i.e. snow thrower). Something as simple as taking 1/4" round stock, putting it under your boots and rolling it back and forth, gives you a decent indicator of where YOU are in balance in boots.
When I stood in a skiers stance and arms positioned as they would be in skiing, I would tip forward from rearward by simply extending my arm very little. My tipping point was directly at the mid sole boot mark (AI).
I think a better way to do this is with two pieces of round stock under your boots, one under the heel and one around mid foot. This would keep you from dorsiflexing as you would with just one under the midsole. Should also have ski poles in your hands.
I was just trying different things to see what would happen. 112 days before skiing starts so can still play with this a bit.
