I'm not seeing that. What I would ask myself is, do I feel my balance centered over my entire foot, that is, am I putting about equal weight on the balls of the feet and the heels? Do I hold steady in that balance, or does it move around? If you're backseated, it's inevitable that weight will be more on your heels, and you'll feel boot cuff pressure on your calves. By definition.
I would be more concerned about ensuring that I'm leaving rounded, continuous railroad tracks in the snow, without kinks or skids. If you're doing more than two turns, you pretty much need to have someone else follow and look at your tracks. In some of the turns, I may be seeing you force the transition a bit, with more up and down than necessary, maybe more of a foot shuffle than necessary, and the first part of the turn a little tighter than the rest, probably slightly skidded. Not to say that it's horrible. That was a lot of turns. The last part of the run looked steeper, so a little skid could have been justified for speed control, if you weren't going to use the full width of the run. Watch your video carefully for any little sprays of snow from your tails. Maybe at 0:34. It's the moment at which the skis are flat, in the transition, that a skier will be most prone to little twist of the feet creeping in.
Maybe others can see more.
