I think they do understand.
They take one look at the orthopedic ankle braces that serve as boots, the heavy bindings and the walking sticks you lot need to stay upright and they thank the mountain they learned to snowboard instead :p
Nordic skiing is different though. thats how skis are supposed to be used
Actually i have never tried alpine skiing so this is just banter. it does look uncomfortable and a lott of faff though.
