Rio » Big fat skis.........78mm underfoot
I think that would qualify as a narrow ski these days; even my touring skis are 88mm underfoot.
sorry, that was the point I was amking but got distracted and didn;t finish. BIg fat skis will help but they are not magic, and you don't need them. If you want to ski knee deep powder, you need to be knee deep, and you won't be knee deep if you're floating on top of everything
I do have a fatter pair but at 92mm underfoot, they're not exceptionally big.
