Built for riders who demand an exact fit and total response, the PSI boot delivers perfect alignment from liner to shell. Its advanced Triple BOA® Fit System allows micro-adjustable customization and a pressure-free fit, keeping you locked in for peak performance and all-day comfort. The integrated BOA® Fit System in the Perfect Fit Zonal Control liner provides precise heel hold and lasting comfort, while two additional BOA® dials on the shell enable independent lacing of the upper and lower boot zones for a truly personalized fit. The upper dial secures your leg, while the BOA® Perform Fit Wrap, controlled by the lower dial, wraps the midfoot for unmatched heel hold, seamless energy transfer, and enhanced board control. Reinforced Aramid mesh strengthens the upper, increasing abrasion resistance and ensuring long-lasting durability.
