Each micro-adjustable system uses unique dial, lace and guide configurations to deliver unprecedented fit and performance. While each component is crucial in optimizing the fit experience, the foundation of the Boa Fit System is the Boa dial.

L6 is the most widely used dial in the L-SERIES thanks to its versatile cartridge system. Designed to keep you going, the two-part design provides maximum impact protection and easy field repair – when extreme force ejects the dial, you can easily pop the cartridge back in get back on the trail.
