last year we took the phase franchise to the next level with the phase boa® pro, and this year were continuing the progression with a step on® model. we added top-of-the-line tech to the simple, skate-inspired upper, starting with the 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.
