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 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.
