Hi there, I have to agree with the previous poster the most important bit of kit for skiing is your boots. If you are doing a season an ill fitting pair will ruin the skiing side of things, I believe there was a famous Austrian ski racer who once said to a journalist “I’ll beat you down the mountain on two planks of wood, as long as I have my own ski boots”.
My advice would be what ever else you are planning on spending money on don’t including beer, mobile phone calls, chocolate, shaving foam etc etc until you get a comfortable well fitted set of ski boots sorted out.
PS Have a great season, still one of the best ways known to man to use up 5 months of your life.
