Local boot fitter back home didn't seem too concerned by a duck footed stance. Having read some similar posts maybe there is something that can be done to accommodate my weird legs and create a more neutral stance.
Boots to suit an abducted stance seem like the obvious option although I have changed boots this season (dalbello lupo kr2) and am otherwise really happy with the fit. A boot with an abducted stance may not suit my left foot very well either.
Re-drilling the ski and mounting the right binding at an angle for my right foot could be an option but it's going to make a mess of my current skis, potentially one to consider the next time I change skis.
Changing the angle of the shin relative to the ski base (maybe through planing the boot base, inserting angled shims under the footbed or binding or just adjusting the cuff canting) seems to have been done by others but it goes beyond my current understanding. Looking at my right foot, when I straighten it inwards it has a tendency raise the inside of my foot and lower the outside. Potentially raising the inside of my right foot may allow my leg to straighten up over the ski. As you can probably tell, I'm guessing!
I asked for a decent boot fitter at the tourist office of the resort I'm staying at (Chappelle d'arbondance) and the girl there sort of laughed and said that there were a couple of sport shops. Any thoughts or comments would be greatly appreciated.
