My local ski shop set me up w/ a pair of Salomon X-Pro 80's. One of my complaints about rental boots had always been foot pain, so we spent a fair amount of time trying on different boots, liners, and insoles. The shop owner said that I should keep the bottom buckles (toe and top of foot) on the lightest tension possible. To his credit, if I do any more than that, I start to get pain in the top of my foot. I don't feel like my foot is sliding around in the boot at all, and overall I'm happy with the boots. I keep the ankle and calf buckles really tight, and I hit my heel on the ground a few times when I put them on to make sure that my heel is all the way to the back of the boot.
Last weekend, a friend of mine (significantly better skier than me) was getting on my case for not buckling my top/toe buckles tight enough. When I explained that my boot fitter had instructed me to wear them that way, he looked at me like I had two heads.
Am I missing something here? What should I be looking for when I wear them to know if the toe/top tension is tight enough?
