For women who want the perfect balance of performance and comfort, the K2 Anthem 105 BOA® is built to charge from first chair to last with unwavering precision. With a responsive 105 flex and a medium-volume fit, it’s ideal for advanced skiers who like to explore the whole mountain—from groomers and glades to steeps and stashes—without sacrificing all-day comfort. The all-new BOA® Fit System provides a micro-adjustable, evenly wrapped fit that enhances control and eliminates pressure points, while the Powerlite shell and Powerfuse Spyne deliver lightweight strength and energy transfer for powerful, confident skiing.

This boot’s PrecisionFit Pro liner offers a plush-yet-secure feel, molded from Ultralon® foam with asymmetric shaping to hug the ankle and provide consistent support. The FastFit instep ensures easy entry and exit, and the heat-moldable shell and cuff allow for a truly customized fit. With GripWalk® outsoles, a non-elastic cam strap, and a women’s adjustable cuff, the Anthem 105 is designed to match the anatomy and skiing style of aggressive female riders who expect both comfort and performance in every run.
