Dynamic ventilation system for socks

A dynamically ventilated sock comprising:

• a toe;
• a heel;
• a part adapted to envelop a foot of a user;
• a part configured to envelop an ankle and a leg of the user;
• and
• an elasticated edge configured to adhere to the leg of the user,
• wherein the sock further comprises a dynamic ventilation system formed of sectors that have different structures and differentiated knitting that enable the sock to acquire well defined functional characteristics, the sectors that have different structures comprising:
• an ergonomic and asymmetric strip structure configured to follow a conformation of the foot, and to contain a plantar arch of the user so as to define a first sector that has a thin mesh with open and sparse knitting to promote the transit of air and a first rapid exit of humidity, the first sector being an integrated aerating portion to enable a corresponding zone of the foot to breathe during movements of the user;
• a first structure with a breathability zone in which an air circulating system is created that is provided for regulating a temperature of the foot and the leg, and for containing and maintaining air between skin of the user and the sock so as to create an air chamber with an effect of insulating the foot and leg from an external environment, the first structure being formed by a mesh which is knitted such that a surface of the mesh is irregular and undulating so as to create an alternation of points of contact with and detachment from the skin with a plurality of microdistances in contact with the skin;
• a second structure consisting of a plurality of contact sectors alternatingly interrupted by a plurality of free portions for the passage of the air, the plurality of contact sectors having greater support on the skin than the free portions,
• wherein the contact sectors are thicker than the free portions and are configured to create guide walls that enable the free portions to act as tunnels between adjacent pairs of the contact sectors on one side, and the leg of the user on another side, so as to act as a guide for overheated and humid air that has to exit,
• wherein the plurality of contact sectors and the plurality of free portions are arranged according to an oblique pattern configured to rotate around the ankle and the leg following a spiral conformation in which the contact sectors contribute to creating an interplay of ridges and grooves that enable a distribution of the air to be managed by increasing the flow of air required for heat regulation and by channeling separately a heated air flow for guided expulsion to the edge of the sock with resetting of a thermal delta of the foot, the second structure having a shape of a spiral that gradually increases towards the elasticated edge;
• and
• a pair of first ribs that are configured as two raised lines so as to create a passage for circulating air and so as to protect an Achilles tendon of the user, wherein each first rib is a cushion that fills with air and has knitting so as to create inside small cavities within which air is present, the dynamic ventilation system being configured to aerate the skin of the user and maintain a dry state during exertions of the user.
