How cross-country skiing works.
When most people think of snow skiing, typically alpine, or downhill, skiing come to mind. However, there are different forms of skiing, and the oldest -- and best, if you ask its practitioners -- is cross-country skiing.
In alpine skiing, a skier generally takes a chairlift to the top of a steep run and skis down it -- both the toe and heel of the ski boot are bound to the ski. But in cross-country skiing, the heel of the boot isn't attached to the ski, allowing the skier to raise his or her heel with each step to approximate a normal walking motion. This enables skiers to travel across a variety of terrains without downward momentum, meaning they can move uphill as well.

Cross-country skiing usually takes place in the wilderness or on a well-worn track. In fact, part of the sport's appeal lies in its ability to let skiers commune with nature and escape into a meditative state -- instead of facing hoards of skiers at an over-crowded resort.
But as easy as it looks, there are many factors at play when it comes to moving oneself across a snowy terrain.
