A semi-rigid binding system includes a toe defining an interior toe pocket with top and bottom exterior surfaces, a heel opposite the toe with top and bottom exterior surfaces and rigid sidewalls opposite to one another which connect the toe to the heel. A top edge of the rigid sidewalls, the toe and the heel together define a top opening of the binding and a bottom edge of the rigid sidewalls, the toe and the heel together define a bottom opening of the binding. As such, the top opening and the bottom opening and an interior surface of the rigid sidewalls form a hollow channel through the semi-rigid binding absent a body sole between the bottom surfaces of the toe pocket and the heel pocket, and the bottom edge of the rigid sidewalls each angle inwardly towards one another.

A wearable water shoe apparatus for walking, standing and jet siding on water, includes in each of a first water shoe and a second water shoe (i) a sleeve to receive a leg of a user and (ii) a bottom section. The sleeve has a platform for standing thereon. Each pair of a plurality of pairs of jet motors is configured to eject a jet stream of water. A stabilization unit, including a tilt sensor and a plurality of gyroscopes, is configured to detect a stabilization state of at least one of the first water shoe and second water shoe. A processing unit is configured to receive output from the stabilization unit, determine a direction of movement indicated by the user and direct at least one of the pairs of motors to eject a water stream out of at least one of the water shoes based on the indicated direction.

A water ski ramp that can be selectively adjusted to provide a variety of launch heights for a jumper is provided. The water ski ramp includes a floating dock comprising a first dock portion and a second dock portion operatively connected to the first dock portion, in which the first dock portion and the second dock portion define an obtuse angle therebetween. The water ski ramp also includes a jumping platform operatively connected to the second dock portion via a dock-to-surface hinge. The water ski ramp may also include an adjustable lift including a first end operatively connected to the first dock portion and a second end operatively connected to the jumping platform, in which the adjustable lift and the first dock portion define an acute angle therebetween.
