Looking to upgrade stock liner in my Lupo AXs as they are way too soft. Fit has been great out of the box with no mods necessary. Looks like I can score a deal on the Max Lite liners out of Lupo Pro HD or a Tour Wrap. Goal is to make the boot warmer and hopefully stiffen it up a bit. I'm using the boot as a 50/50 boot for easy tours and inbound skiing. Anybody skiing either of these liners?
