The Dalbello Viper 8 is a boot for the athletic intermediate to advanced skier who is looking for a comfortable, and performance fit all rolled up into one. Dalbellos Contour 4 Fit Concept has mapped some extra room in the four most common problem areas for your foot to hurt inside a ski boot. The ankle, heel, fifth metatarsal, and navicular have all been pre-punched for added comfort and a better anatomical shape to improve your comfort and performance on the slopes. Dalbello has also engineered the Viper 8 to have a Center Balanced Stance by aligning the cuff angle, cant angle, and cuff inclination angle to adapt to more modern ski technology like oversized sidecuts, and rocker profiles to give you more power, and better balance behind your skiing. The 3D Power Frame is tri-injected that bonds three different density polymers into one structure to give you a boot that has precise foot wrapping, a direct power transfer, and is easy to enter and exit. A 90 flex gives stronger skiers enough drive, power, and rebound for you to have a comfortable fit without sacrificing any performance. A 45 mm powerstrap acts as a fifth buckle to give you more leverage and power behind every turn. If you are a stronger skier who has a medium to narrow forefoot, and are looking for a boot to enhance you skiing the Dalbello Viper 8 will be a great boot for you.
