Ski boots are sized in mondopoint, your foot length in centimeters. Last width, the width of the boot's forefoot, comes in narrow, medium and wide ranges. Flex index is the boot's stiffness; softer boots suit beginners and lighter skiers, and stiffer boots suit aggressive and heavier skiers. A fitted boot feels snug, with toes lightly touching the front when standing and pulling back when you flex forward.
Boots matter more than skis. A good fit gives control and comfort.
