Definition:

Randonee skiing, also known as Alpine Touring (AT), is a form of skiing in which athletes ascend the mountain under their own power through the use of specialized bindings and skins.

Skins are held on the bottom of the skis with a sticky substance, they were originally made of animal skin but are now of an artificial material that have fibers to hold the skis from sliding back down as the skier glides forward up the hill.

Once the skier reaches the desired altitude the skins are removed and the bare skis are used to descend.
