  • Patent number: 11234483
    Abstract: An item of footwear such as a boot (10) includes a stiff lower part (12) that extends around part of a wearer's foot, a stiff upper part (16) that extends around the wearer's lower leg, and one or more limit elements (66,72,80,88) that extend between the lower part (12) and the upper part (16). The lower part (12) and upper part (16) are movable relative to each other when the ankle moves and the relative movement is inhibited selectively by the limit elements (66,72,80,88). The limit elements (66,72,80,88) are displaceable between a free condition in which the lower part (12) and the upper part (16) are movable relative to each other, and lock condition in which the relative movement between the lower part (12) and the upper part (16) is inhibited.

    Abstract: A knee brace (10) according to the invention includes an upper leg formation (12), a lower leg formation (14) and a hinge mechanism (16) that is disposed entirely on the lateral side of the knee. The knee brace (10) has pressure formations (20, 24,62, 28) pressing on three pressure points: on the lateral aspect of the wearer's upper leg, on the lateral aspect of the wearer's lower leg, and against the knee complex on the medial aspect of the distal extremity of the femur. The three pressure formations are connected to one another by a stiff structure (18, 16) which includes the hinge mechanism (16).
