The Panterra 90 from Dalbello is great for intermediate to advanced skiers: the Panterra Shell with VVF (Variable Volume Fit) allows you to change the forefoot width from 100-102mm with the first toe buckle. And, 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 rearward mobility - great for standing or 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 here at Ken's to accelerate the breakin process for a comfortable fit on your first day! The Contour 4 Shell has expanded the four zones that most problematic for bootfitters so you can achieve additional comfort and more efficient skiing.
