Help! I'm going to a ski resort (Chamonix) for the first time in March/April. I won't be skiing or snowboarding but will presumably have to walk around on/in snow as I'll be taking kids to and from ski school. What footwear do I need? Can I get away with warm but probably not waterproof boots (this sort of thing) or do I need waterproof? Would wellies with warm socks & legwarmers do? I've always managed fine with wellies or combat boots at home but 3 inches of snow is OMG FREAK WEATHER where I live. Please don't tell me to buy proper ski boots as I am very broke :( thanks!
