In reply to WrekinMC:
I got a pair of snowshoes in Canada in 2003, and tried using them the next time I walked in to Sneachda. After ten minutes of floundering ridicule, I abandoned them and just walked in like everybody else. Fortunately they only cost C$15.
There may be a specialised technique to walking in snowshoes. I don't know, and I'm never going to find out. What's certain is that, for my part, I don't find skis any harder to use: the contrary, in fact.
And what happens if you're in snowshoes and it gets really icy? Of course if you were on skis, if it was bad enough, you'd still have to switch to crampons and axe, even in descent. But I reckon you can ski things that are a lot icier and steeper than you can snowshoe.
