Skier and Racer Alignment, it's not art, it's science.

Here are some examples of skiers 13 years old, with good alignment. There are 6 different skiers here, how lucky I am to have 6 different skiers with perfect alignment????? 

People think this is normal, they are all naturally talented and perfectly aligned. I have coached this group for 6 years and everyone of them has some adjustments under their boots. Every time they change boots we have to find the new optimal set up. This is done by on snow analysis and indoor measurements. Indoors to keep track of the norms, outdoors to test the skiers movements and ski angles. We sometimes change the alignment after each run, to test what works best. 

Every leg here is lined up perfectly with the forces. There is no undue stress on the knees or joints when alignment is correct. Skiing can be rough on the joints. At this age you would never realize it. One of my goals as a coach is to reduce as close to eliminating any opportunity for injury with every possible technical innovation. Alignment is one of those that is always addressed in our training.
