Not sure if this is a repost but ive seen some threads and no one has mentioned this. Try putting the power strap underneath the tongue. Someone told me to do it today and it stops any movement in the top of the boot! Try it.
If your boots fit well, then you should never get pain in the shin. I ski 4-5 days a week and never get any pain in my boots at all. If somthing hurts then somthing is wrong with the fit of the boot, doing things like you sujjested might help, but its not fixing the cause of the problem.
its a little different skiing 5 days a week on east coast ice.
even if your boots fit perfectly i guarantee that they will start to hurt a little if you are lapping the park 9-4 5 days in a row. lap after lap pounding down on solid ice landings 20 times a run puts a beating on your body
it's not really a dumb thread. i've used fulltilts for years with the strap under the tongue. the lower part of the boot fits my foot perfect, but i've got really skinny shins so putting the strap under is the best way to keep the top of the cuff snug without maxing out the top buckle. no shinbang, nice flex, it's all good.
