Well this is my first post to this forum. Probably someone will tell me that this issue has been discussed X times before, but here goes...
Watching my wife ski I can observe that her outside ski often has a wider turn radius than her inside ski, from approximately the midpoint of the turn onwards. This results in the front tips of her skis being further apart than the tails. I've seens this phenomenon to a smaller extent even on pictures of expert racers, but in her case it seems a bit extreme, especially when she skis aggressively.
My first thoughts were that she must have her weight too far back on the ski, but when I watched her ski past (so that I could see from the side) she looked quite nicely balanced over the ski. Could there be other explanations?
She is a reasonably aggressive skier, about 75kg skiing on Volkl AC3 163cm. One issue which might or might not be relelvant is that she has relatively fexible boots (flex about 60 if I remember right). She bought them after a long struggle to find some boots which fitted (that's another story, the problem is that she has very large calf muscles relative to the size of her foot), but I wonder whether she gave up too quickly and has settled for something which doesn't allow her to transfer enough power into the ski?
Anyway, any suggestions would be interesting to read.
