Any thoughts on a quick fix or do I need to find a ZipFit or other fitter in Vermont?
it can take a day or two for them to settle to your feet at the start of the season, especially as you only had a day or 2 in them so far... i normally reckon on 3-4 days hard skiing to bed the liner in properly
how are you putting the boot on... liner first or in the conventional way? if the latter then make sure you are lifting the back of the liner out and letting your foot pull it back down to ensure you are in the right place (under the heel huggers) there are some hints and tips on the zipfit.com website which may help
heat is your friend, you don't want to damage footbeds but making sure the boots are warm at the start of the day will always help with zipfits especially in stiffer shell
