RADIUS: Defined by sidecut, the radius governs the natural turn circle of skis. The radius of curvy slalom skis may be 12m; straighter big mountain skis could be 44m. Some skis are multi-radius, meaning the turn circle changes along their length (wide at the front, tight at the rear). That's why skis in our reviews may have two or more radius figures.

REVERSE SIDECUT: Some powder skis with rocker get wider instead of narrower from the tips back towards the middle of the shovel, before narrowing again towards the waist, to help with float. The same may apply at the tail. 

RIPPER: An accomplished skier or snowboarder who knows how to shred.

ROCKER: A ski shape characteristic, which causes the tip and tail to rise away from the surface of the snow, making it easier to manoeuvre in soft snow, and less likely to catch an edge.
