If you can make it over the hill to Richterswil, I can recommend Hans Vetsch at Sportis. He sorted out my previous pair of boots that a "recommended" "boot fitter" in Courchevel had done (too tight, caused permanent nerve damage in my big toe), and then fitted my current pair of boots several years ago, but they're still great.

One thing to bear in mind, though, is you almost certainly won't be able to get anything done until after the end of Feb now with the new lockdown
