To use these boots, first loosen the BOA® Fit System dials. Slip your feet into the boots and then tighten the dials to your desired level of snugness. Make sure the SUPERLOCK heel harness is properly adjusted to prevent heel slip. When it comes to maintenance, after each use, wipe the boots clean with a dry cloth. If they get wet, let them air - dry naturally away from direct heat sources. Avoid storing them in damp places. Also, check the BOA® Fit System regularly for any signs of wear and tear.
