Sock for patient use, the sock comprising a tubular mesh structure flexible at least in its transverse direction such that a foot of the patient is not compressed, the tubular mesh structure comprising single-element monofilaments, adapted in at least two layers so that the monofilaments of each layer are adapted mutually substantially parallel and crosswise in relation to the monofilament of the subsequent layer, and each monofilament is at each intersecting point where the monofilament intersects the monofilament of the subsequent layer welded to the intersecting monofilament of the subsequent layer, the monofilament being formed of a material with a high friction coefficient which high friction coefficient means that the monofilament is formed of a material that has a higher friction coefficient in relation to the common floor surface materials, in other words, a higher static coefficient of friction and/or kinetic coefficient than the common sock materials such as cotton, wool, polyamide, acryl, or their combinations, typically formed as knitted fabrics of various kinds, and the tubular mesh structure being formed to be closed at one end by closing the tubular mesh structure at one end by melting or welding so that the sock forms a bag-like mesh structure, wherein the material with a high friction coefficient comprises synthetic rubber material and/or thermoplastic elastomer, and wherein the sock is entirely formed of a mesh structure formed by said single-element monofilaments or the sock further comprising a slide block formed of a material possessing a lower friction coefficient than the friction coefficient of the mesh structure, and being fixedly adapted to the mesh structure by welding. a tubular mesh structure flexible at least in its transverse direction such that a foot of the patient is not compressed, the tubular mesh structure comprising single-element monofilaments, adapted in at least two layers so that the monofilaments of each layer are adapted mutually substantially parallel and crosswise in relation to the monofilament of the subsequent layer, and each monofilament is at each intersecting point where the monofilament intersects the monofilament of the subsequent layer welded to the intersecting monofilament of the subsequent layer, the monofilament being formed of a material with a high friction coefficient which high friction coefficient means that the monofilament is formed of a material that has a higher friction coefficient in relation to the common floor surface materials, in other words, a higher static coefficient of friction and/or kinetic coefficient than the common sock materials such as cotton, wool, polyamide, acryl, or their combinations, typically formed as knitted fabrics of various kinds, and the tubular mesh structure being formed to be closed at one end by closing the tubular mesh structure at one end by melting or welding so that the sock forms a bag-like mesh structure, wherein the material with a high friction coefficient comprises synthetic rubber material and/or thermoplastic elastomer, and wherein the sock is entirely formed of a mesh structure formed by said single-element monofilaments or the sock further comprising a slide block formed of a material possessing a lower friction coefficient than the friction coefficient of the mesh structure, and being fixedly adapted to the mesh structure by welding.
