But what on earth is going on with my leg? It only happens on this horse (a true widebody). My saddle sits correctly - I'm in the deepest part of the seat, and feel well-balanced. I've tried having a longer leather, but then I actually barely reach it and my foot comes out at a canter. So I tried just dropping my leg without the stirrup at all to see where it ends up, and it naturally falls right where it is in this pic. So for kicks I've tried to force my knee further down to bring my heel into better alignment with my body, but I can't - it's like doing the splits, and my leg loses most of the contact with the horse's body. It's no biggie. I ride trails, I'm comfortable, I'm in control, but for someone who's always been a stickler for correct position, it's REALLY annoying. Why is this happening? This is the widest horse I ride. Any suggestions for getting my leg fixed?
