Zoltan, When I did the shell test, I did remove the liners.
I just did the shell test again right now and I have 1 finger and 1-2 millimeters maximum.
Thumper, what I did instead of cutting a sock is to bend the sock back down to the middle of the feet. This way I have 2 thickness of fabric at the ankle area.
I went carving like this on sunday but it was hero snow so I do not experience heel lift on hero snow, only on hard conditions (snow accumulations).
I used to have non-themo liners in my former AF600.
It's my first year with thermoflex liner, I can not say that I'm impressed. It's not taking room as I thought it would be. From what I've read on the forum, I was thinking that thermo-liners were amazing...
I'm expecting some pads this week, I want to make my boots as thight as my ice hockey skates.
I forgot about UPZ, since I have never seen a carver wearing those I did not thought of them.
Anyway, let's pray for the snow gods to give us some snow again and prevent the evil rain gods to do their stuff, I want to carve again in March, it's too soon for soccer yet
