Rollerblade Viablade series skates are Rollerblade's entry level hard boot skates. All the skates of this series feature:

Tri-force technology: this breakthrough technology supports the parts of the foot that generate power and then re-distributes that energy out to toes and heels.
Bi-injection molding: Rollerblade's patented molding technology puts stiffer material into areas that need extra support and provides plenty of ventilation throughout the boot.
Three buckle memory closure featuring aluminum buckles. These skates remember your sizing adjustment. They fit the same way every time you put them on.
L-Pad Heel Pockets to ensure proper fit and support of the heel.
ABT Automatic Braking: Rollerblade's patented braking system for new skaters that lets you come to a fast, safe, stop without  taking any wheels off the ground! The only system of its kind!
