A footboard for play, exercise and practice of aerial maneuvers and recreational moves on a jumping device. The footboard is preferably flexible in a variety of directions, but has sufficient firmness so as to allow the board to retain a desired shape. The footboard is attached to the user's feet by a strap system, which holds the user's feet within recesses in the board itself. The footboard is preferably waterproof or water resistant for use on water trampolines, in lakes and swimming pools. Handgrips may be provided at one or more locations of the footboard, which, combined with the flexibility of the board, enhance the moves and style of the practicing foot boarder.
