Abstract: Footwear with energy accumulation is presented. In a first version, the footwear comprises a sole, back, associated therewith, and fixation means coupled with the sole and back for securing a user's foot on the sole. The sole and back are disposed at an initial angle exceeding 90° therebetween, and form a leaf spring, while being arms of the spring. Alternatively, the leaf spring is made separate from the sole and back, having two arms respectively coupled with them. In a second version, the footwear comprises a sole including a frontal portion and a rear portion, the frontal portion is formed as a console spring downwardly bent out and cantileveredly secured to the rear portion, and fixation means for securing the user's foot on the sole, coupled therewith and depressing the front part of the foot against the spring. The portions are disposed at an initial angle therebetween less than 180°.

Abstract: The supporting element of gravity footwear, made up in the form of a shoe, a boot etc. with accumulation of energy, caused by deflecting, comprising flexure spring, the topmost of the shoe equipped with fixing device, joined to the spring, sole and other elements of the shoe, is made up in the form of a heel, or a heel and a sole, or a sole, gravitational effect on the spring is communicated by a cuff and/or a stiff cover as well as out of any other soft suspending element, wherein the distance between the ends of the spring when load is not applied to the spring is greater than the distance between a point of suspending and the lowest point of the user's foot, the spring is equipped with a fixing device. The heel is a supporting element within the spring unit, jointly used with conventional footwear as a device, intended to accumulate energy and comprising a flexure spring, joined through the element, which communicates gravitational effect on the spring and the user's foot.
