Unlike traditional petroleum-based polymers, Pebax® Rnew® polymers are advanced materials made from a renewable feedstock: castor beans.

Pebax® Rnew® materials used in the ski boots are >65% bio-based.

The Castor bean is truly a remarkable crop:

  • Grows on marginal soils
  • Does not cause deforestation
  • Does not compete with food
  • Captures atmospheric CO2
  • Provides stable revenues for farming families

Every boot powered by Pebax® Rnew® materials helps the farmers and their families sustain a better life.


The bio-based origin of the material does not induce any compromise on the performance. Pebax® Rnew® polymers are world leading high technology polymers, designed for high-end sports equipments.

Their unique properties include:

  • Lightness: Pebax® Rnew® polymers are typically 20% lighter than most other plastics. This brings maximum confort
  • Extreme toughness and shock resistance for improved durability and enhanced lifespan
  • Sustained performance under extreme conditions, especially at cold temperatures
