The Panterra 75 GW from Dalbello makes a great ski boot for the intermediate to advanced skier who has a medium to narrow forefoot and medium shaft of the leg. The Panterra Shell allows you to adjust the width of the shell by adjusting the first buckle on the toe from 101mm thanks to the VVF (Variable Volume Fit). Once that toe buckle is set you never need to unbuckle it to put on or take off your boots. A Hike/Ski Mechanism unlocks the upper cuff from the lower shell for more rearward mobility for easy walking. Dalbello's Center Balanced Stance is more upright to drive extra energy and less fatigue when you are riding on modern skis with sidecut and rocker. The TrueFit Sport Liner can be heated by a ski shop to accelerate the breaking in process for a comfortable fit right out of the box. The Cabrio Design on this boot will comfortably secure this boot to the foot and lower leg while keeping its smooth and progressive flex.
