How to use: First, put on the R3 liner with PrimaLoft® insulation. Then, insert your foot into the boot. Use the BOA® Fit System to adjust the tightness according to your comfort. Make sure the SUPERLOCK heel harness is properly in place to prevent heel slip. Note: Avoid wearing these boots in extremely wet or non - snowboarding environments. They're designed for winter snowboarding. Maintenance: After use, remove the liner and let both the liner and the boot dry naturally. Don't use direct heat sources. Regularly check the BOA® system and the heel harness for any signs of wear and tear.
