Footbag & Hacky Sack FAQ

'Hacky Sack' is a trademarked brand name that became a generic term for the game. 'Footbag' is the broader sport name used in competitions and freestyle play.

Today the words are often used interchangeably, but 'footbag' covers competitive disciplines like freestyle, net, and golf, while 'hacky sack' usually refers to casual circle kicking.

Players stand in a circle and keep a small filled bag in the air using any body part except their arms and hands. The goal is to pass the bag from player to player without letting it hit the ground.

In freestyle footbag, players perform tricks and combos using only their feet, knees, and other legal surfaces.

In casual circle hack, the main rules are simple: no hands, no consecutive touches by the same player, and don't let the bag touch the ground.

Competitive footbag has formal rules. Freestyle routines are judged on difficulty, execution, and variety. Footbag net is played like volleyball over a net. Footbag golf uses the fewest kicks to reach a target.

Beginners do best with a two-panel sand-filled bag like the Dirtbag or a soft crocheted bag. These bags are forgiving, stall easily on the foot, and are inexpensive.

As control improves, many players move to smaller, firmer freestyle bags with metal or plastic filling for precise stalls and tricks.

Freestyle players usually prefer 32-panel or 42-panel synthetic bags filled with small metal or plastic pellets. The Flying Clipper Pro Series, World Footbag Pro Bag, and similar competition bags offer a firm, round shape that stalls predictably.

The footbag was invented in 1972 by John Stalberger and Mike Marshall in Oregon City, Oregon. They originally called it 'Hacky Sack' as a way to help Stalberger rehabilitate an injured knee.

After Marshall's death, Stalberger trademarked the name and the sport spread worldwide through the 1970s and 1980s.

Casual footbags are usually filled with sand, plastic beads, or millet. Freestyle and competition bags often use metal shot or dense plastic pellets for a firmer feel and more predictable stalls.

The filling changes the weight, bounce, and how the bag sits on the foot, which is why different fillings suit different styles of play.

Quality footbags are sold directly by specialty makers like World Footbag, Dragonfly Footbags, and Flying Clipper, and through marketplaces like Amazon.
