Don't mean to lecture but I see too many instructors with this attitude and use it as an excuse to ignore educating themselves in this realm. SAD. I am not advocating doing anything irresponsible or dangerous. I agree 100% and I know that many instructors will use liability as an excuse for not trying.
Who here has been dragged into court regarding alignment or boot fitting related issues? I would be curious to here more from these people! Not for boot fitting issues specifically that I am aware of yet but everything else under the sun. in Ohio its easy to sever the instructor from the resort and single them out in court and the experience usually results in the instructor hanging up their teaching hat and buying a pass. This is a very litigious state, especially in auto accidents. Once in a while there is a test case. Last year the Ohio Supreme court ruled in favor of a snowboarder whom hit a skier. The court basically said getting hit is one of the inherent risks. You never know how cases will work out here.
Properly aligned boots actual greatly reduce the chance of injuries do to the tremendous stress poor alignment places on joints and ligaments. So if an instructor knows a student is at danger, is it their duty to warn them? Morally yes, legally not usually.
I have been asked to write a more detailed paper on what symptoms to look for to help identify issues in each of the 10 parameters I have identified. I am working on it and hope to help PSIA divisions work this info into their certification processes. It needs to be addressed and is a glaring shortcoming in today's resort ski schools. Note that private ski camps such as Epic Ski Academy, NASTC, Harb camps, etc. have embraced proper alignment as an integral part of their programs. Resort ski schools have bucked this topic for various reasons, one being they don't see an immediate bottom line profit potential, the other is their risk management departments are paranoid about their exposure. I don't understand how resorts can build all the sick terrain features and jumps in their parks and pipes where skiers and boarders are badly injured on a regular basis yet offering a service that actually makes skiing more enjoyable and safer gets shoved aside???? My efforts here through the ski school have raised awareness greatly at our resort. I have given talks on alignment though the SS. SAM is seeing some benefits in customer satisfaction and things are moving in the right direction. I am certainly getting more ideas to improve things in the forums.
