SHOES WITH ACCUMULATION OF ENERGY GENERATED IN PROCESS OF MOTION Russian patent published in 2010 - IPC A43B7/00 A43B5/00 A43B13/18 A63B25/10 

FIELD: personal demand items.

SUBSTANCE: shoes with accumulation of energy generated in process of its use comprise shoe upper and heel joined to each other with fixing elements for fixation of foot position in shoes, and also plate spring, according to invention, shoe sole and heel create plate spring, moreover, initial angle between sole and heel, which are spring arms, is more than 90°, and shoe upper provides for the possibility to change angle between sole and heel and is arranged from elastic material or comprises easily deformable inserts, for instance corrugated ones. In shoe, sole and heel that create spring, are arranged from elastic polymer material. Initial angle between spring arms is selected depending on its properties, and also purpose of shoes and physical resources of user. Cross section of spring may be arranged as permanent or varying in length. Elastic properties and rigidity of spring may be permanent or vary in length and width. Spring may have sections with C-shaped cross section for partial coverage of foot. In shoes with accumulation of energy, by means of alternating feet rest onto support surface with simultaneous deformation of spring and displacement of feet using energy of spring release, according to invention, primary touchdown is carried out onto forefoot, and spring is deformed in process of further lowering of heel part. Spring is deformed till full or partial rest of foot onto support surface.

EFFECT: improved efficiency of user weight application for accumulation of energy for user foot push and improvement of his or her safety, provision of possibility to change character of user motion due to initial touchdown not onto heel part of foot but rather upon forefoot, which makes it possible to most efficiently use physical resources of a human being, in particular to provide for an efficient operation of ankle joint and Achilles tendon.
