I have tried them on artificial slope three times (less then one hour each), and have no pain. But I believed that they are not snug enough, so I try to adjust everything from start and wear a thicker sock. Then I found that my right toe was jammed. Now, I can feel the pressure on my right toe even without buckle.
I try a shell fit, two figures behind heel, but the lateral space is limited may be 1/8" each side.
1. Is it because my foot have swelled, so now it is too tight, but not before? (or I just do not feel it before?)
2. How much a foot will shrink on slope, where the temperature is low?
i don't know why your feet would be swelling since feet tend to swell mostly in very low pressure conditions e.g. airplanes. although your feet aren't going to be super toasty, the temp inside your boot isn't that adverse if it's a good fit and the liner is in good shape.
first off, everyone above has great sound advice about general boot fitting, read up. getting a boot that is too big or too small is a big no-no, whether or not you are a newb or expert. although the liner may pack down a bit and the footbed will conform to your feet, don't expect a dramatic change. if it feels too tight or too loose when you try them on, it will probably continue to feel that way even after a few days.
trying your boots on an artificial slope won't help you determine correct fitting... you need real conditions as a baseline. cold temps stiffen a boot whereas trying them on in a store and on astroturf will make almost any boot seem a lil soft and mushy.
do not compensate for a bad fit with thick socks. your feet and skiing will only suffer. also, if your buckles are on the first or last rung, they need to be adjusted or the boot is just the wrong size for you.
the only methods of fine tuning a fit should be the addition of a booster strap, custom footbeds, and adjusting the buckles. if you need something a bit more dramatic, sanding down the inside of the boot or moving the buckles to another bracket set should do the trick. of course ask a professional boot fitting techy about anything you do.
there are so many things to add about how a boot should fit that it'll fill thread after thread, so do a search here and in other forums and study up.
