Pros: Well crafted and the best heel hold ever
Hands down this is the best investment I've ever put into my ski boots. That includes custom foot beds and numerous shells. Arguably this is dependent on how well your shell fits and your foot shape (what else is new?) but without question I'm so pleased with these I'll never put any other liner in my boots. I've got a narrow swim fin shaped foot ,even narrower heel ,so every boot fitter I know wants to put me in a racing shell (for the narrow last) unfortunately not even the best racing shells could give me the security of a locked down heel I get with these.
