Abstract

Footwear insole (1) comprising a soft upper layer in contact with the foot and an underlying plantar layer (3), wherein a thin copper foil (4), composed by a continuous layer a few tenth of a millimetre thick, is placed between said upper layer (2) and said plantar layer (3).

Description

FOOTWEAR INSOLE * * *
The present invention relates to the sector of footwear. In particular, the invention relates to a footwear insole to be used in different models of footwear. According to the prior art, common shoes are usually provided with insoles comprising a thin upper layer in soft material, usually leather, in direct contact with the sole of the foot, and a lower layer completely or partially waterproof, usually in polyurethane, forming the orthotics of said insole. The waterproof layer that is always placed in correspondence to the back part of the foot, can be substituted, towards the toe, with a hygienizing composite layer, containing active carbon, for example. It is well known that nowadays, shoes, and in particular the structure and composition of the insoles therein inserted, have a very important wellness function since they enable the right physiology of the foot and allow the positioning of the centre of mass of a person's body in the right way both in dynamic and static conditions, thus ensuring the right posture of the same. The aim of the present invention is to improve and increase the beneficial effects of footwear insoles.
The aim is achieved by a footwear insole comprising a soft upper layer in contact with the foot and an underlying plantar layer, characterized in that it comprises a thin copper foil placed between said upper layer and said plantar layer. Advantageously, the abovesaid copper foil is a continuous structure, without any cut or interruption, both longitudinally and crosswise.
According to a preferred embodiment of the invention, the thickness of the copper foil is of a few tenths of a millimetre, the length is of 100- 120 mm, the width is of 12-15 mm.
Equally advantageously, one face of said copper foil is provided with an adhesive layer.
Said adhesive layer enables the fixing of the copper foil underneath the upper layer of the insole, typically in soft leather.
The leather layer that is in direct contact with the sole of the foot is conveniently provided with at least a small hole disclosing the actual presence of the underlying copper foil.
Preferably, the foil extends longitudinally from the middle of the heel to the sole of the foot.
The solution as described can be applied both to insoles having a composite plantar layer with a hygienizing layer arranged towards the toe and to insoles having plantar layer in one piece.
The advantages of the present inventions are basically: - weight distribution, according to a law of physics, from the heel to the rest of the foot sole;
- anti stress effect, because copper enables the release of tension caused by electrostatic charges;
- antibacterial effect, thanks to the electric field generated by the positive electric charge of the copper, which acts as a barrier against bacteria thus improving hygiene and sanitation;
- thermoregulation, since copper has very high heat conduction capacity;
- reduction of stress on the postural system. Further features and advantages of the invention will be more evident from the following detailed description and with the help of the figures by way of non-limiting examples.
Fig. 1 shows a top view of a footwear insole as described in the present invention. Fig. 2 shows a longitudinal section of the insole of Fig. 1.
Fig. 3 shows an exploded view of the insole of Fig. 1 , disclosing the main parts forming the invention.
Figs 1 and 3 disclose that the insole footwear 1 basically comprises an upper layer 2, usually in soft leather, a lower layer in waterproof material, called plantar laye.r and a thin and continuous copper foil 4 between said two layers.
Figure 1 shows, in detail, the exact position of the copper foil 4, extending from the middle of the heel to the sole of the foot; moreover, it discloses the presence of holes 5, having a diameter of about 1 ,2 mm, in the upper soft leather layer. Alternatively, said holes 5 can be substituted by a single hole, whose diameter is of 4-6 mm. The width of said foil 4 is of 12 to 15 mm, and the total length is of 100-120 mm.
Fig. 2 shows a side view of the insole 1 , in which one can see (from the bottom upwards): the plantar layer 3 extending, towards the front part, in a hygienizing layer 6 (not necessarily present); the thin copper foil 4, a few tenths of a millimetre thick, and the upper soft leather layer 2, provided with said holes 5.
In case of the presence of the hygienizing layer 6, containing active carbon, the upper layer 2 of the insole is provided with further small holes 7.
The copper foils 4 are directly obtained from copper foil reels already provided with adhesive substance on one side and covered by oil paper. Said reels are cut into small rolls from which the foils of the desired length are obtained. The above described invention enables a better distribution of the body weight as well as a decrease in stress to the postural system.
It also has anti stress and anti bacterial functions, beside acting as a thermal regulator thanks to the heat conduction capacity of copper.
For a skilled man it is obvious that the invention is described by means of a non-limitative example and it can be applied to any footwear insole, independently of the use to which said footwear is destined.
