Designed for those looking for a full featured boot with amazing performance and comfort comes the Dalbello Panterra 90 GW Ski Boot. The Panterra Shell allows you to adjust the width of the shell by adjusting the first buckle on the toe from 100-102mm 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 Contour 4 Shell has expanded the four zones that are the most problematic areas for bootfitters to make adjustments to, for additional comfort and efficient skiing.
