This is the reply I got regarding the Pilot Classic binding problem. My eventual solution was to go NNN. I suspect it's definitely one of those "works for those with lots of maintenance available" type of products.
The high end Salomon boots are made on a very narrow last. You have to have quite narrow feet to fit into them properly. That was the second reason for switching to NNN. Alpina and Rossignol fit wider. It may not make a difference in this situation but if your feet are being pinched in while constantly flexing, who knows what nerves are being rubbed?
Classic Pilot Binding Tune Up
Over the past few years, Team Salomon skiers have been using the Salomon Classic Pilot binding in almost all of its races in Canada and the US, and have encountered various snow conditions. Typically, the binding seems to 'release' at the second attachment point when fresh or dry blowing snow fills in the track. The best way to get the most performance out of your Salomon Pilot Classic binding in this case is to follow these steps prior to skiing - In most cases, this solution seemed to resolve the issue.
1. Set your spring tension to '3' or higher
2. Use a silicon based spray - bought at any local hardware store - and spray the white plastic component and 'tongue' at the second attachment point. Pull the tongue out with your fingers and spray generous amounts of silicone on both sides of the fabric as well as inside the binding's interior. For best results, do this process indoors, while the ski is dry or free of snow. NOTE: Binding performance will be affected if this procedure is done with there is snow already on the binding.
3. Repeat the process a second time to ensure that the second attachment point is well covered with silicone.
4. Prior to getting on snow, ensure that your ski boot sole AND binding is completely clear of snow.
5. Go out and enjoy all the benefits of the Pilot system!
