===Nordic===
In Nordic skiing the skier is not reliant on ski lifts to get up hills, and so skis and boots tend to be lighter, with a free heel to facilitate walking. Styles of Nordic skiing equipment include:
* [[Cross-country skiing|Cross-country]] [[Cross-country skiing#Skis|skis]] are light and narrow, with a slight [[sidecut]]. Three binding systems are popular: [[Rottefella]]'s NNN, Salomon's SNS profil, and SNS pilot. Ski bases are waxed to reduce friction during forward motion, and [[Ski wax#Grip wax|kick wax]] can also be applied for grip. Some waxless models have patterns on the bottom to avoid the necessity of grip waxing for classic technique.
* Skating skis are shorter than classic skis and do not need grip wax. The skating technique is used in [[biathlon]]s.
* [[Ski jumping]] skis are long and wide.
* [[Roller skiing|Roller skis]] have wheels for use on dry pavement, in the absence of snow.
