Because testers use their own skis for boot testing, the boot's effect on stance balance, and ski performance are easier to spot. Some boots are rigid and transmissive, making skis feel shorter and sharper. Other boots flex and twist easily, making skis feel less responsive and long. Stance angles are easy to register as some boots make for a tall, elongated stance and others a more bent-kneed position. A boot's side-to-side alignment has an obvious affect on edge angle. Here test director Mark Elling is about to check the new Dalbello Panterra 120's shock absorption. Turns out this landing was molar-rattling flat.
