<p>The invention relates to gravitational footwear in the form of a shoe, boot, etc., which accumulates energy generated by elastic deformation and comprises a flexion spring and a footwear upper with fixation devices connected to the spring, the sole and other components of the footwear, wherein the bearing member of the spring is in the form of a heel, or a heel and a sole, or a sole, and gravitational action is transmitted to the spring by suspending the user's leg relative to the top of the spring by means of a sleeve and/or a non-elastic hose or by another soft supporting member, while the distance between the ends of the spring in a free state is larger than the distance between the suspension point and the lowest point of the user's foot, and the spring includes a locking member. The spring unit can be used together with conventional footwear as an attachment for accumulating energy, and includes a flexion spring connected to the user's leg by a member for transmitting gravitational action to the spring, wherein the heel is used as the bearing member of said spring and the sole is used as an additional bearing member when the spring is compressed.</p> |
