A longtime DC favorite, the Phase is now available in a high-performance Pro model that adds top-tier tech to its skate-inspired simplicity. The BOA® System provides a more precise for improved stability and board control. This year we made it even better with our brand-new, patent-pending SUPERLOCK heel harness. The SUPERLOCK system is attached to the BOA dials through harnesses that quickly pull your foot securely into the back of the boot to eliminate heel slip and ensure a more responsive ride. To top it off, the Phase BOA Pro is also equipped with our premium R2 liner and molded IMPACT-ALG™ insole to maximize comfort and performance. Simply put, we built the Phase BOA® Pro with all these performance-focused updates to conquer the most technical riding in the harshest winter conditions.
