Replying to Agent 80 trouble?

So ive been riding with my technica agent 80 ski boot for just about a full season now and im starting to have some serious trouble with these boots.  Ive already had to relpace the toe and heal things on the bottom of my boots twice this season, though this isnt really anything to worry about. thats just from walking around.  what buggs me is that one of my buckles cracked in half, apparently frum the mettal just being too cold, and that ive had to relpace my liners with a pair to nordica supercharger liners cause the technica ones got large holes in the heals.  i feel like i shouldnt have to relpace this many things on a pair or skiboots after only skiing on them for 100 or so days.  I don know tho. Just wondering if anyone else has had any problems whith these boots.
