The Boa Advantage. 

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.

M2 is engineered with a 2:1 gear ratio, making it easier to get the fit that you want. Quick lace take-up and powerful closure allows for micro-adjustment in the harshest weather and extreme environments.
