Part of me thinks that the use may not be as bad as walking around in boots that are not designed to be walked in. But that goes for things like motorbike boots too.
5 people killed in an avalanche in Tirol about 10km from where we are skiing currently. Feels strange as we had some really fun days including some nice off piste runs.
I'm always amazed at people still using those. a) they were shit and b) they are ancient lol
But if you are just gliding around (ie: not a lot of stress on the boot), I'm sure they will last a lot longer
