The Women's Felix Step On Snowboard Boot provides a responsive flex pattern and plentiful support while effortlessly engaging into our Step On bindings in mere seconds. It uses a Dual Zone Boa system, which provides independent tightening over the external boot shell and ankle zones, to secure us in much like the ankle straps of a traditional binding would. Like all of Burton's Step On boots, the Felix provides plenty of comfort thanks to a specialized midsole with integrated cushioning and a supportive, thermo-moldable lining.
