FIELD: medicine.SUBSTANCE: group of inventions relates to medicine. Orthopaedic device for a lower limb of a human, including a front segment suitable for receiving the sole of a forepart, and a rear segment suitable for receiving the lower surface of the heel. Front segment and rear segment consist of two separate parts. Front segment and rear segment are connected by at least one resilient upper arch which extends above the front segment and the rear segment, providing a recess for receiving the foot, and is suitable for maintaining the front segment and the rear segment in an inoperative position, such as to enable a relative movement of the front segment and the rear segment relative to one another, from the inoperative position, and to resiliently return said front and rear segments to the inoperative position. Shoes equipped with an orthopedic device for the lower limb of a human, comprising a front segment configured to receive the sole of the forefoot, and a rear segment suitable for receiving the lower surface of the heel. Front segment and rear segment consist of two separate parts. Front segment and rear segment are connected by at least one resilient upper arch which extends above the front segment and the rear segment, providing a recess for receiving the foot； is configured to hold the front segment and the rear segment in an inoperative position； is configured to move the front segment and the rear segment relative to each other from an inoperative position and resiliently return the front and rear segments to the inoperative position. Prosthesis of at least one part of the lower limb of a human is provided with said orthopedic device.EFFECT: inventions reduce the inadequacy of foot lift muscles, the lifting effect at the beginning of the step when walking, the propulsive effect at the end of the step when walking or, alternatively, when running and the stabilisation effect, and in particular lateral stabilisation of the lower limb of a human, especia
