The sleeves of the foot and shin are made of a composite material based on a polymer composition. In the shell of the foot, a carbon strip and a fabric of synthetic high-strength filament along the longitudinal axis of the foot to the axis of the metatarsophalangeal recess and in the joints with the petal of the ankle joints are additionally stacked, and in the shank of the shin the carbon band is laid, starting from the joints of the sleeve with the ankle-lobes upwards with the intersection of overlapping on the back surface of the shank sleeve in the lower third of it and to the upper edge of the lateral surfaces of the shank sleeve, as well as in the places where the sleeves are fastened. In places where the elastic ankle joint is fastened to the shins, a fabric made of a synthetic high-strength yarn is also inserted.

EFFECT: invention ensures the reliability and comfort of the device's socks, allows to reduce postoperative and rehabilitation periods.
