Zipfit Grand prix ski boot liners, in my opinion the best liner on the market, this liner will conform to the shape of the shell and foot over and over for the life of many sets of boot shells or even many different users, a cork based filling is heat moldable and can be molded every day for around 450 days of use.
When the shell wears out just put the same liner into a new shell and reheat it to mold to the new shell shape, the liner can have more cork filling added at any time or even removed if there is too much, the only requirement is that the shell has to be the right size and shape for the foot within reasonable limits.
The grand prix is designed for race and lower volume shells.
Providing an optimal balance of foot-to-shell contact so you get ultimate power and accuracy, while you get some level of padding and comfort.
You’ll wring all the performance available from your high-performance boot shell.
