A contact system for a sport board allows a rider to maintain contact
between her feet and the sport board while performing aerial maneuvers.
The boarder wears magnetic footwear such as a bootie (for surfing),
sheath (for surfing), or shoe (for skateboarding) with an affixed magnet.
The board has a contact patch that includes a plate of ferrous metal or
another magnet oriented such that it attracts the magnetic footwear. The
contact patch is positioned such that it will be stood on by the boarder.
During normal boarding and aerial maneuvers, magnetic attractive forces
between the footwear and the contact patch will maintain contact between
the boarder's feet and the board. However, when the boarder falls, the
magnetic attractive forces do not bind the boarder's feet to the board.
