FIELD: articles of personal use.
SUBSTANCE: invention relates to footwear ensuring energy accumulation, including footwear for everyday use, sport footwear for running, jumping, footwear for mountaineers, as well as footwear used as rehabilitation means for recovery of work capacity of foot ligaments and muscles. In footwear with energy accumulation from lamellar spring deformation, including upper part of footwear, sole and fixing elements for fixation of foot position with respect to sole. Anterior part of sole is made in form of bent downward, fixed cantileveledly with respect to remaining part of sole lamellar spring, fixing elements also ensure pressing of anterior part of foot to sole spring. Upper part of footwear has possibility to ensure periodic change of angle between spring and posterior part of sole and is made from elastic material or contains, in zones subjected to stretching and contraction, easily deformed inserts, for instance crimped. Angle between bent spring and remaining part of sole from the side of support surface is less than 180°. Zone of fixation and bend of sole spring can correspond to beginning of metatarsus, sole toe phalanxes or can be nearer to heel. Spring can be made from elastic polymer material or from other elastic material. Initial angle of sole spring bending can be chosen depending on its properties, as well as footwear purpose and physical possibilities of user. Cross section of sole spring can be made constant or variable in length. Elastic properties and rigidity of sole spring can be constant or variable along length. Sole spring can have parts with C-shaped cross section for partial covering of foot. Anterior part of sole spring can be made curved, for instance for cohesion with projecting roughness of support surface.
EFFECT: increase of efficiency of energy accumulation use for user foot push and increase of their safety.
