I went to a boot fitter before even looking for boots. He's one of the good ones that knows what boot will work best based on your leg shape and stuff and SIZE. He specifically recommended these.
They are PERFECT. The added precise fit and stiffness gave so much more responsiveness to my skis.

Remember, the boot has the most number aspects you can go wrong and you shouldn't go out and buy a boot that feels most comfortable. Boot fitters are your friends. He certainly guided me to my perfect boot. They felt almost too tight, but you have to give them about 5-6 days to pack out. I also got the newest year's (in Feb) for a SICK price at backcountry.com

This boot is great. I consider myself an aggressive skier but have a large sore spot on my right ankle from shattering it in the army. This boot provided very stiff flex with one of the most comfortable liners I have ever tried. After a few sessions the liner feels great around my foot.

It keeps me forward and aggressive without worrying about my ankle.

Very stiff boot with comfortability to match.

I took the boots down for the custom heat molding. The molding was excellent and the boot is very comfy but I would caution against heating them and cranking the boots down. Now, I have a hard time putting them into "race mode" If I did it over I would have heated them and put them on just tight enough to to not wiggle. That way, they would be molded but still have some pressure potential when I crank 'em down.

These boots have done very well both on piste and some Masters level racing. I have yet to really tackle any big mountain or off-piste terrain but I feel the boots will do just fine. I noticed they have the custom sole plate, and I have no idea how to adjust the arch support. I will be interested to see how long they last since my last pair of boots made it more than 2 decades.

Coming off race boots, I was a bit worried about the stiffness (lack of) of the Impact 10s, a 110 flex rating. After skiing on them for 5 days in both powder conditions and east coast ice, I have been impressed however with the boot's performance. It is pretty comfortable providing a large enough yet supportive foot cavity. The liner materials are great. The boot is not too soft and responds well to forward pressure. My feet got a bit sore in warmer conditions, but the pain was relieved relatively easily by unbuckling on the lift. No doubt, Salomon makes a superior boot.
