|A couple things to try first. Head down to the thrift shops (Sally Ann, Goodwill, Valu Village, etc.) and find a pair of $5.00 plastic shell inlines with liners that fit you. Put the liners in your quads and try them on. If they're too tight in the toes, cut the toe area of the liners back a little at a time till you find the spot where things fit comfy. They may seem a little warm at first but you get used to it (it does get hot here in Canada too). New aggro liners go for $40 to $75 a pair so you don't want to be slicing up new ones.
Don't cut your skates down. You'll destroy them. There's plastic and nylon and foam that will turn into a big mess. You don't need to tie them all the way to the top. Ice and inline hockey skates are not meant to bend sideways like quad boots need to so there's no way they'll be comfortable done up to the top. Just up to the ankle bone is plenty. If you switched to speed boots that's as high as they would go anyway.
: : You could try wearing a pair of aggro inline skate liners inside your boots, if they're really too big for you. That would pad things up a lot.
: Hey, you might be onto something. How thick are they and where can I get a pair? Do they have holes in them to cool off? If I can get 1/4th inch liners all around, it would do for now.
