There's nothing worse than waking up early, suiting up for an awesome day of riding, and making it all the way to the summit, only to find that your feet are painfully sore. Alleviating the discomfort of ill-fitting boots, the K2 Women's Sapera Boa Snowboard Boot features a Boa lacing system with Tailored Zonal Fit. Instead of tightening the entire boot evenly like a traditional Boa system, Tailored Zonal Fit gives you three settings with upper zone bias, neutral tightening, and lower zone bias. This way, you can fine-tune the boot's fit and feel to your exact riding tastes and local terrain. Creating a supportive fit, the Intuition Control Foam 3D liner molds to your foot as you ride throughout the season. This thermo-moldable liner features internal J-bars that hold your ankle for locked-in security without fatigue-inducing heel lift. Softening flat landings and harsh vibration, Harshmellow at the heel and forefoot offers a smoother riding experience. To keep the boot extremely lightweight without sacrificing grip, the Phy-Lite sole is low-profile with strategic traction lugs.
