Plastic core skis

Plastic

— plastic is less suitable for serious loads than wood, therefore it is used very rarely, mainly in cross-country skiing. Such skis have a notch on the underside in the middle part where the boot is located, which allows them to do without lubrication. On the other hand, the plastic surface tends to slip when moving backwards, and lubrication may still be necessary in some conditions. Also note that plastic cross-country skis are made only for the classic course.
