All very good advice here. I might add- Are you buckkling up super tight? Many guys think they have to crank down on their boots to get control. Or.. "the racers crank 'em down, I should too!" Go looser. Try sking with the instep buckle completely unbuckled. Some feet just don't like being squished. Mine are like that. Also try a softer inner boot. I have Salomon Super Force with a flex index of 115. Super stif puppies. I had them stretched out and deflex. 1000% better. I still have some numbness now and then but a softer inner boot might help me. <note> I had to fight my ego "I'm making this race boot softer. Gee! I won't be a 'dude' skier anymore!" Bull! The boot is more forgiving, I don't get thrown into the backseat anymore, with a softer flex I don't cut off my ciculation so much, balance is great now, I ski faster with great form. I'm doing things I used to do 25 years ago and better.
Nothing is worse than a bad fitting boot!
