Technology

Elastic Response System
Skis flex when compressed or while jumping, thanks to Elastic Response System the heel piece slides towards the tail and repositions itself once normal conditions are restored.
- Safeguards the natural flexibility of skis.
- Enhanced release mechanism in the event of falls.
- Reduces the pressure on the ski-boot-binding system.

ESS
This system is characterised by a new design of the toe part. A smooth step-in which is safe and easy to fit, available on all the latest models and effective even if the soles are worn.
 

Please note: your stoppers size should be the next bigger one, depending on your skis´ waist (E.g.: waist 100mm -> 102mm stoppers).
The “size” selection refers to the stoppers' width.
