Gravity boots

Gravity boots, while shaped like and worn like a boot, do not serve the same function as the footwear. They are ankle supports designed to allow a person to hang upside down. Thanks to exposure in television dramas and movies in the 1980s, gravity boots became a common fitness tool in homes across the United States. Today, gravity boots are used by the U.S. Army and have experienced a surge in popularity in 2006 with Da Vinci Code author Dan Brown praising them as well. Several companies manufacture and market gravity boots under various trade names.

The purported benefits of gravity boots range from the relief of back pain and headaches to increased oxygen flow to the brain. Some people use gravity boots to add an extra challenge to workouts, doing inverted crunches or squats, while others such as Uri Geller and Dan Brown use them as tools to help them generate new ideas.
