Abstract
Devices, systems and methods are described for launching a projectile. Preferred devices comprise two separate platforms that are connected by an elastic cable. Each of the platforms can be secured to one foot or shoe of a user by a strap or other fastener. Once secured, a force can be applied to a projectile that is connected to the elastic cable to thereby stretch the cable in a first direction. Once the force is removed, at least some of the elastic force of the cable can be transferred to the projectile causing the projectile to be propelled in a direction opposite to the first direction.
