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 equipped with our patent-pending SUPERLOCK heel harness to eliminate heel slipping and deliver a more responsive ride. And this year we made further upgrades by using our super-responsive R2 liner with the extra warmth of PrimaLoft insulation. Simply put, the Phase Boa Pro Step On is one of our most advanced women's boots ever.
