    FAQs

    Try-on essential?

    Ski boots especially. Half-size off = miserable day on slopes. Get fitted at specialty shop first time. Online ordering only after you know your exact MP + brand last.

    Heat moldable?

    Many high-end ski + snowboard boots are heat moldable. Shop heats boot, you wear with custom liner, cools to your foot shape. Adds 30-60 min but lasts the boot's life.
