Barefoot skiing

Barefoot skiing is water skiing behind a motorboat without the use of water skis, commonly referred to as "barefooting". Barefooting requires the skier to travel at higher speeds (30–45 mph/48–72 km/h) than conventional water skiing (20–35 miles per hour/32–56 km/h). The necessary speed required to keep the skier upright varies by the weight of the barefooter and can be approximated by the following formula: (W / 10) + 20, where W is the skier's weight in pounds and the result is in miles per hour. It is an act performed in show skiing, and on its own.
