The BOA® Fit System is incredibly powerful, as it designed to wrap stiff shells around your feet, to provide the utmost performance and confidence. However, if the BOA® Fit System is overly tensioned without a foot inside of the boot, the power of the system risks permanently deforming the plastic of the shell and can lead to leaky boots and improper fit. For these reasons, Fischer recommends storing BOA® enabled boots with no or minimal tension in the cable, especially for prolonged periods when the boots are not in use.
