Deep Progressive Sidecut – The radius progressively gets longer as you move towards the nose, but it is centered and very short between the feet for instant reactivity and a consistent feel with riding switch.

All-Mountain Freestyle Shape – Sidecut is still deep progressive for edge grip but slightly offset towards the tail for more stability at high speed; Shape is directional with a 1- to 2-cm insert set back for versatility; Tail is stiff for pop; Waist and Nose are softer for smoothness.

Dual Torsion Box C/K – Split the core into 3 sections, lock 2 of them in a fiberglass sock, overlay them with strips of Carbon and Kevlar, top it off with a full wrap of fiberglass and what do you get? Punch, enhanced durability, ridiculous edge grip and forgiving edge-to-edge transition.

Twinwood Core – Rossignol’s classic core made with 2 types of wood, Poplar and Fumé: smooth like butter, but with the pop of a skateboard.

4.4 Sintered Base – This high-density stone-finished sintered base is fast, durable and a lot easier to service. Stone Grind Base Finishing – This base is 2D stone structured for a very low friction rate and perfect durability.
