Last year we took the Phase franchise to the next level with the Phase BOA® Pro, and this year we’re continuing the progression with a Step On® model. We added top-of-the-line tech to the simple, skate-inspired upper, starting with the Dual Zone BOA® Fit System paired with our patent-pending SUPERLOCK heel harness to eliminate heel slip and deliver a more responsive ride. We also fitted it with our R3 liner with PrimaLoft® insulation, our warmest and most responsive ever. Simply put, the Phase Boa® Pro Step On® is one of our most advanced boots ever.
