But this was not too far off. The knock knee is the position that Liz would have used before in order to get her skis flat on snow. But now, becase the outsides of her boots were planed down, she is on her outside edges instead of flat skis. It's hard to tell from the before sequence, but it looks like Liz's natural before stance was legs tight together from the hips to the feet. Would this help to minimize problems cause by undercanting. Does the new alignment force her legs apart from the knees to the feet? Liz still spends a lot of time with her legs locked together in the after segment, but she spends more time with her feet apart than before.
I tried to downplay the above (after) pic as an example of out of alignment because of the before and after positions and I noted the weight in the back seat. I said , but now I'm also going to add that the inside ski on new edge was not working because of weight too far back AND knock knees. The really cool part is that, with my new understanding, this pic shows CORRECT alignment. What a cool alternate way to visually check alignment!
the dark color between her legs provides some evidence that she had her feet apart before she got angulated, then closed her feet together later in the turn. It's kind of funny because after she puts her feet together, they skid apart and she goes right into the next turn with her feet apart and it works beautifully.
But even if under cantedness hurts angulation is true for Liz, I don't think it proves the general case. If one was skiing old fashioned racing style with the inside ski unweighted, it would seem that being too much on the inside edge of your outside ski would make you appear to be more angulated, but otherwise would make little difference.
When you have some weight on your inside ski and it is less edged than it should be due to undercanting, you're going to have to skid the inside ski more to keep the skis parallel. My guess is that if the inside ski skid is achieved by foot rotation, it would be easy for inside hip rotation to accompany that. It's been my observation that good angulation includes a leading inside hip and that banking happens when the hip is more rotated to the inside. But this thinking is way too complicated. But there are other ways to adjust. There must be a simpler answer.
I tend to think of banking versus angulation as different positions from the knees up. These differences would be unaffected by different relationships between the feet and the knees. This would give me the answer that, at best, cantedness would have an indirect effect on angulation. Note that I don't like this answer either. In the absence of debate, I'm documenting my own conflicts.
Bud, would my approach to measuring hip angulation reduce the impact of cantedness impacting the measurement? Because I draw my lower body line from between the feet to between the hips, any alignment problems that bow the knees in or out ought not to matter, right? Looking back at the first before and after pics I did, it seems that the harder it is to draw the lower body line, the more likely it is that there is an alignment problem.
Note to DC: It would be real cool to have before and after views (including a few seconds of both head on and from the side views) where alignment was the only change. If we separated out the video from the what was done it would serve as a nice quiz for pros. For the head on shots it would be nice to show a straight run with a normal stance, a straight run with a "cowboy" stance (feet ouside the hips) and a straight run knock kneed.
Bud, do you have any more suggestions for before and after shots?
