^ that is probably the dumbest thing a dad can do all things considered, safety should be the top priority. Loose boots that don't fit properly are not SAFE, especially for this type of skiing. Go to the shop and get fitted and buy new boots before you get hurt. Honestly tell him not to be ignorant, it isn't 1930, we live in a technology filled environment and you don't need top of the line but you need proper fitting gear. If he still refuses, go behind his back and buy buy buy
