The 2021 Sapera Boa Women's Snowboard Boots feature a Boa lacing system with a three-point liner harness that prevents your heel from slipping during carves. This combination of quick-lacing Boa and three-point liner harness maintains the supportive, locked-in feel desired by riders charging the entire mountain. An articulated shell maintains a consistent flex and feel without it bulging outwards or deforming after a heavy season of use. And with a medium flex, the Sapera crushes any type of terrain, giving you enough freedom for riding park with support for charging steeper lines.
