BOA® Fit System on the Cuff and Shell:
The BOA® Fit System shell delivers dialed in performance and a micro-adjustable precision fit. It consists of three integral parts: a micro-adjustable dial, lightweight yet extremely strong laces and low-friction lace guides, which are applied in uniquely designed configurations to improve the fit and performance of the boot.
The BOA® cuff single cable design allows the tension to self equalize always giving a consistent pressure to the shin. The improved wrap allows for better power transmission and improved comfort even at high tension
