Dry fitting my binding today to get a new perspective on my stance, I noticed that due to how duck footed I am (my feet point excessively outward when my knees face forward), my hips must not square up to the ski well. My guess is that with my back foot in a rtp, the back foot rotates to compensate and my hips open up to the boat quite a bit on my onside, and don't quite square up to the ski on my offside. I lack a stacked stance on my offside as I bend at my hips too much which I'm guessing is in part due to this.
Trying my uncle's ski with double bindings, I noticed that while my hips are forced to be more square to the ski allowing my upper body to do more of the work in opening my shoulders up to the boat, but I loose a significant amount of mobility, ability to bend the knees, and control over my stance as my knees both bend inwards together, and it's a lot harder to stay on my front foot on offside turns.
For reference, when I squat at the gym, I have to point my toes out so that my knees can bend straight forward. If I try to keep my feet parallel, I can't go nearly as low as my knees start to come together in a very weak and flexibly limited stance.
Current PB (no tournaments) is at 36mph and I feel in control, but know that this is an issue in technique that will limit me later if I don't solve it soon.
Anyone else overcome this? Do you just live with buying rotatable bindings to angle outward (seems like a serious compromise that no hardshell can accommodate as far as I know)? Do you use double boots and ski long enough to force yourself to adjust? Corrective exercises?
Sorry if there is a previous thread on this, as I couldn't find any. Looking forward to your advice!
