3/ Well adjusted ski boots
When you're about to attack your day's skiing make sure you adjust your ski boots well, ensuring good support, but don't tighten them up too much, to avoid compressing the blood circulation and making your feet cold.
Then adjust them as the day goes on: the foot adapts to the boot, the shell relaxes or contracts depending on the temperature, the liner itself settles a little during the day.Don't hesitate to tighten or untighten the bucklesas soon as any discomfort is felt or when more support is needed, it is the best way to stop any discomfort setting in.
Good to know:
Many ski boots are equipped with micro-metric buckles:the buckle can be extended to allow more volume or, on the contrary, tightened for better support. The ratchets can also be moved to gain volume, essential for example when you have a bigger calf or an instep that is not very high.
