The Vi-Concept is simple but effective. Clap Snap Wrap is how you do it. Open the flap, close it and tighten it by turning the disc knob. This will give you an completely new skating feeling, total control with perfect fit. 360° lacing and the full wrap technology make it possible. The shell is stiff and light with a sleek and narrow look and feel, while offering all the comfort you need. The shell is the first and only fitness shell that is not symmetric, but is perfectly shaped and anatomically built to the skaters feet. Moon boots and soft and flimsy skates are past, the Vi-shell is here to take over. It is made out of a special composite compound with carbon and fiberglass mixed into the material. This makes the shell strong and supportive. The Vi-shell also features a 195mm mounting with the Powerslide X-slot, which enables the skater to adjust the frame to the side and to the front and backwards, for the perfectly customized frame-boot position. The bottom is ventilated and incorporates the X design to guarantee torsion stiffness and perfect power transfer for each stride. This is not just an evolution Vi is a revolution.
