Description

Sole structure for breathable shoes {SOLE STRUCTURE FOR A VENTILATED FOOTWEAR}

The present invention relates to a sole structure for a breathable shoe.

EP 1 300 090 discloses breathable walking shoes comprising a midsole under the upper. These midsoles are made of felt, or other suitable natural fiber, covered by perforated insoles made of leather or leather, and the midsoles do not require pre-lasting and lasting operations. Arranged in the peripheral edge of the insole to engage the upper of the shoe.

A box-shaped rubber sole window arranged below the midsole includes a hole in the central region of its edge portion, the hole being in a perforated member made of a membrane or leather or leather of microporous, transpirational and impermeable material. Covered by the absence of bonded felt or natural fibers. These holes are wholly defined by the edges of the bottom window to prevent degradation of the continuity of the edges thereof.

Although the breathing effect on the wearer's foot has proved to be effective and particularly preferred, a disadvantage of the prior art solutions is that the above-mentioned transpiration and impermeable membranes coupled to the felt member may be subjected to repeated bending of the sole during walking. This results in exposure to a fatigue working cycle, which can quickly deteriorate the same membrane, causing the membrane to break, resulting in at least a partial loss of the impermeable properties of the shoe, And mud can seep in.

Another disadvantage of the above-mentioned prior art solutions is that the tread of the shoe is provided in a single unitary structure with a box-shaped sole comprising a hole in the edge of the shoe, which solution is a tread of various shapes. It is not possible to make any modifications in the use of soles in shoes intended for use only or with different applications from walking. In fact, when a manufacturer manufactures breathable shoes for a different purpose than walking, such as sports shoes that require treads of more complex shape, for example, the manufacturer may be able to install new box-shaped soles provided in various shapes of treads and required holes. It is necessary to manufacture.

This lack of modularity can be costly as new molds are needed to produce breathable shoes with different shaped treads in various sizes of soles.

In addition, providing a box-shaped sole integrated with the tread as a single unitary structure introduces the additional disadvantage of not being able to substantially replace the tread when worn, in fact the tread is only replaceable when it has a sole separate from the upper of the shoe. Do. Such work is quite complex and expensive, and in particular can degrade or significantly damage functionality and integrity, such as impermeability of the shoe.

WO 2008/138778 partially solves the disadvantages of tread replacement or fatigue of the membrane due to fatigue and modularity when the tread wears, but the embodiments disclosed in this document concave on the outer surface of the midsole. Between the seat and the outer securing member, there is a membrane made of microporous, transpiration and impermeable material arranged outwardly on each side of the midsole so that the membrane is free of possible damage due to stones, gravel, mud or dust during walking. Exposed to blocking.

It is an object of the present invention to solve the above-mentioned problems of the prior art solution by providing a shoe structure for a breathable shoe that is effectively ensured durability and reliability for a long time.

Within this conventional object, it is an object of the present invention that one or more components of the ventilation system, ie membranes made of microporous, transpiration and impermeable materials, are damaged or blocked by stones, gravel, mud or dust. It is to provide a breathable shoe sole structure that can prevent the build-up and significantly reduce the quality degradation caused by repeated bending of the shoe during walking, thereby effectively preserving the impermeability and transpiration of the shoe for a long time. At the same time, the long time durability and reliability of the shoe can be significantly extended.

Another object is to improve the ventilation efficiency inside and outside the shoe ㅏ.

It is a further object of the present invention to provide a shoe structure for breathable footwear which can be manufactured at economical cost using conventional and readily available tools and devices.
