• Dual Core

  The DUAL CORE technology involves injecting materials with different hardness levels into the same mould, with three injection points in the shell and two injection points in the cuff. The result is a sandwich construction with an ultra-thin layer of hard materials on the outside encapsulating the softer materials inside. This technology can be used to accurately fine-tune the progressive flex, rear support and rebound, and also allows for highly effective lateral power transfer.

• SEAMLESS TOE BOX

  To increase the thermal insulation, Rossignol has designed a liner with a toe box that retains heat inside the liner. Thermographic studies show that this new design has reduced energy wastage by around 20%.
