Skiers with extra wide, high-volume, hard-to-fit feet, we see you. The Mach Sport EHV 120 (Extra High Volume) features a 106mm lasted liner, and is designed for advanced skiers that have extra wide, high volume, E-EEE width feet. A solid 120 flex won't buckle under the pressure of a larger, stronger skier, while the NFS liner with celliant offers a great anatomical fit for support, comfort, and warmth so you can enjoy a full day out on the mountain.
