Abstract: A protective assembly for a limb, in particular the shaft-forming part of a motorcycle boot, which is designed to protect the tibia of the motorcyclist. The inventive assembly includes: an essentially tubular body (2) including a slit, which extends along a longitudinal axis (6) and which is designed to fit around the limb; a rigid tongue (10) which is designed to cover the front part of the body and which extends along both sides of the slit; and a flange (12) which extends transversely to the longitudinal direction between the edges of the slit, the flange being adjustably-connected to the body on either side of the slit so that the distance between the edges can be adjusted. The aforementioned tongue is mounted to the flange such that it can slide freely and the tongue and the body co-operate in order automatically to align the tongue in relation to the slit.

Abstract: An item of footwear, particularly a motorcycle boot (1), includes a rigid shell (4) which defines a body that is designed to surround the foot of the user. The body consists of a lower sole-forming part (20), an upper vamp-forming part (22), an inner lateral part and an outer lateral part, the lateral parts connecting the aforementioned lower and upper parts. The inventive item of footwear includes an opening (16, 18) in one of the four constituent body parts, which passes through the rigid shell and which is sealed by a flexible half-sole (12, 14).

Abstract: A footwear designed for a plurality of sports for protecting a user's feet and legs includes a first rigid shell defining a body (2) adapted to receive a user's foot and extending along an elongation direction (8); a second rigid shell defining an upper (4) designed to receive the user's leg and extending substantially along a rising direction (10); an articulation (6), linking the body to the upper, having specific mechanical strength characteristics. A range of articulations having different mechanical strength characteristics can be fixed to the first and second shells to accommodate the physiological differences between the various uses of such footwear articles and/or to the differences between the various sports for which the footwear articles may be used.

Abstract: An item of footwear is intended for sports practice and is used to protect the feet and legs of a user. The footwear includes: a first rigid shell defining a body (2) which is designed to receive the foot of the user and which extends in a horizontal direction (8); a second rigid shell defining a shaft (4) which is designed to receive the leg of the user and which extends essentially along a vertical axis (10); and a connection (6) which joins the body and the shaft and which is used to rotate the shaft in relation to the body along two essentially-perpendicular rotation axes (8, 12) and to move the axes of the connections in relation to the body, such that the axes of rotation of the aforementioned connection essentially coincide with the axes of rotation of the foot in relation to the leg of the user.
