A longtime DC favorite, we once again upgraded the Phase BOA Pro to make it one of our top performing boots. This year we added our premium R3 liner with PrimaLoft insulation for our warmest and most technical fit. We also paired the Dual Zone BOA Fit System with our patent-pending SUPERLOCK heel harness to eliminate heel slip and deliver a more responsive ride. The Phase BOA Pro mixes skate-inspired simplicity with top-line tech features to conquer the most technical riding in the harshest winter conditions.
