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 slide 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 skiing technique.
