Replying to Re-Expand boot liners that have compressed?

I have EEE wide feet. I bought Dalbello Prime 75s, which have a wider footbed than most boots. I didn't heat the liners (they aren't heat-moldable). They worked great for around seven days skiing, but lately I'm getting a hotspot on my outside left foot. I also notice that I'm on the tightest hook on the lower buckles, and if I go for the looser hooks, there's no tension on the buckle. I think I progressively overtightened the buckles while skiing, and ended up with completely compressed liners. Is there any way for me to get them to expand back to where they were originally? Or a way to add padding so that the buckles will work on the looser settings?

Noteworthy points:

I wear thin wool socks.
I weigh around 200 pounds.
I'm an intermediate skiier, but I like a firm fit on the boot.
I'm kind of ham-handed, and I do have a tendency to overtighten things.


Thanks
