The Prion is ideal for riders who want the comfort of an entry level boot but want a bit more support & response. By integrating a TPU backstay into the polyurethane & textile upper, the Prion gains a more responsive & dynamic flex without overly effecting its smooth friendly nature. This enables you to push your riding a little bit harder without worrying that the boot will punish you for any mistakes. Internally, the Level 1 custom fit liner moulds completely around your foot to enhance comfort. Combine this with the anatomical heel retention system which helps secure your foot in the boot & you get one of the best fitting boots on the market which gives superb feel & control. The main focus of this boot is to offer a blend of comfort & flex which is perfect for beginner/ intermediates who want to ride all over the mountain & push things to the next stage.
