A footbag is a small bean bag or sand bag used as a ball in a number of sports and games. It is typically controlled by the feet, but in some sports every part of the body except the hands and arms may be used.

Both the footbag and the sports that use it are sometimes referred to as Hacky Sack or hackey sack.

Footbag was invented in 1972 in Oregon City, Oregon, when John Stalberger met Mike Marshall, who had been kicking around a hand-made bean bag.

Although some argue that certain types of shoes are necessary, the only piece of equipment that is really required in order to play footbag is a footbag. These come in many styles, colors, and varieties.

Some footbags have simple cotton exteriors, while others are made of 2 to 120+ panels of suede. Generally the more panels a bag has the more spherical its shape and the more difficult it is to stall.

Freestyle Footbag is a footbag sport where players demonstrate their abilities by performing sequences of difficult moves. The objective is to perform a series of tricks linked together.

Circle kick is the most common game played with a footbag, and it is the game people usually refer to when they talk about “hacking.” Players stand in a circle and keep it moving around the circle, without having it touch the ground or hitting it with hands.

In footbag net, players (either playing for themselves, or with a partner) move a footbag back and forth across a five-foot-high net. This game combines elements of tennis, badminton, and volleyball.
