Sock with functional biomechanical, circulatory and neurological efficacy

A sock comprising:

• a foot part;
• and
• a leg part,
• the foot part being designed to overlap a foot of a user and the leg part being designed to overlap at least one part or an entire part of a leg up to below a knee,
• optionally the foot part being closed by a toe part,
• said sock being made of a layer of mesh having, one or more areas of said sock, a structural modification element that is applied on said mesh,
• wherein the structural modification element consists of a thickening element of a wall of the sock that extends over an entire foot vault or along an entire foot bottom and/or along an entire triangle of the foot vault,
• wherein said thickening element extends, without interruption, up to an area of insertion of an Achilles tendon,
• wherein the leg part presents a length such as to overlap a calf part ending below the knee, the thickening element extending, without interruption, up to a calf area, where the thickening element divides into two branches that diverge each other towards a lateral leg area,
• wherein the two divergent branches of said thickening element after bifurcation extend respectively upwards and so as to follow a conformation of calf muscles, so that a branch of the bifurcation is located at a medial twin muscle and another branch of the bifurcation at a level of a lateral twin muscle,
• wherein said thickening element is constituted by a continuous band of material having a predetermined width and a predetermined thickness, said continuous band of material extending seamlessly from an anterior end of an arch of the foot, at an extremity towards metatarsals, up to an opposite end, to ends of the two divergent branches when said thickening element extends up to and along the calf area,
• wherein the thickening element is formed by a band or a strip of material associated with a knitted wall of the sock in an area intended to overlap anatomical areas at the foot vault, the entire foot bottom, and/or an triangle of the foot vault, an area of insertion of an Achilles tendon, a material of the thickening element having a lower extensibility than an extensibility of a remaining wall of the sock, and
• wherein said band or strip of material is applied to an outside of a knitted fabric that forms the wall of the sock.
