We like skiing in K2's Anthem Pro Ski Boot when we want to perform our best down difficult lines. It's K2's stiffest ski boot built for women, and as such, it can handle full days of powder, steep chutes, and icy summits—whatever the resort has to offer. Despite its narrow fit, the Anthem Pro's thermo-moldable shell and liner customize the boot's shape to your footshape to ensure solid comfort on the slopes.
