In reply to sam1971: I've made shapes in the snow like that, years ago, wearing mountain crack pros, on blades and big feet. But the technique needed to have control and survive was more akin to ice skating, than sking. I've since matured(slightly) and realise I was probably lucky, plus young strong legs may have helped prevent anyserious damage or accidents.
For the sake of a few hundred quid, better to get the right kit, than risk spending the next 10, 20, .... years with a restricting or nagging knee or ankle injury.
