With reference to figures 1 to 10, there is shown a sole 1 for an athletic shoe 2 (such as a running shoe, football shoe, tennis shoe) or a work shoe (particularly a shoe approved for work) or leisure shoe, the sole comprising a main or top part or mid-sole 4 defining a plurality of channels open towards the top or away from a base part 3 or away from the base part of the sole. Such channels are provided for accumulating sweat from the user's foot; at least one outlet opening or

outlet area

5a, 5b is also provided, which is in fluid communication with said plurality of channels and opens to the outside of the sole 1 for the discharge of perspiration accumulated in the sole. The channels are actually recessed in the top member or midsole 4.

Advantageously, the sole also comprises a ground-abutting or sole or base element 3, provided or not with a heel, and in this case a top or mid-sole 4 fixed or constrained to the base element 3. Alternatively, the main component or midsole 4 may be provided with a base portion or sole or ground-engaging portion made or formed at the respective outer or lower surface.

It is clear that the sole element or ground abutment portion or base element 3 may be provided for the entire extension of the sole or even only at the head end or front portion F or at the rear portion R.

Preferably, the top part or mid-sole 4 is integrally formed or made of a single piece, for example obtained by moulding a single piece or moulding several pieces glued together. The thickness of the top or midsole 4 may vary from the rear portion R to the front portion F of the sole 1, for example decreasing gradually from the rear portion R to the waist and then substantially constant or increasing slightly from the waist or intermediate portion to the front portion F.

Preferably, also the base portion 3, if provided, is integrally formed or made of a single piece, for example obtained by moulding a single piece or moulding several pieces glued together.

Furthermore, the plurality of channels comprises at least two main

longitudinal channels

6, 7, 8 extending at least partially in a direction from the rear portion R to the front portion F of the sole 1, and at least two first or terminal

transverse channels

9, 10 extending at least partially in a direction generally from one side 11 to the other side 12 of the sole 1, and each transverse channel crosses or extends from near one end of one main longitudinal channel 6 of the two main longitudinal channels to near one end of the other main longitudinal channel 7 of the two main longitudinal channels, if desired.

The main

longitudinal channels

6, 7, 8 extend at least partially in the direction from the rear portion R to the front portion F of the sole 1, in the sense that at least one of their ends is closer to the front portion than the other end and vice versa, but they do not necessarily extend straight parallel to the direction of the rear portion R-front portion F, but they may also be curved or inclined, completely or partially, with respect to the rear portion R-front portion F direction. However, the distance between the ends of each

channel

6, 7, 8 in the rear R-front F direction is at least equal to 1/4 or 1/3 or 1/2 or 2/3 or 3/4 of the length of the sole.

The plurality of channels also includes at least two second or intermediate transverse channels 13a-13h extending generally in a direction from one side 11 to the other side 12 of the sole 1, and each channel, if desired, traverses or extends between two or more of the main

longitudinal channels

6, 7, 8, particularly from a mid-section or portion of one of the two main longitudinal channels 6 to a mid-section or portion of the other of the two main longitudinal channels 7.

The

transverse channels

9, 10, 13a-13h extend at least partly in a direction from one side 11 to the other side 12 of the sole 1, in the sense that they are at least one end closer to one side 11 than the other and vice versa, but they do not necessarily have to extend straight parallel to the direction from one side 11 to the other side 12. Conversely, they may also be completely or partially curved or inclined with respect to the direction from one side 11 to the other side 12. However, the distance between the ends of each

transverse channel

9, 10, 13a-13h in the direction from one side 11 to the other side 12 is at least equal to 1/4 or 1/3 or 1/2 or 2/3 or 3/4 of the width of the sole.

If a third main longitudinal channel 8 is also provided, the

transverse channels

9, 10, 13a-13h preferably intersect or cross the third main longitudinal channel 8 during the passage from the first main longitudinal channel 6 to the other or second main longitudinal channel 7.

Preferably, the

channels

6, 7, 8, 9, 10, 13a-13h communicate with each other to constitute a structure of the top part 4 having protrusions or

islands

14a, 14b, 14c, which are delimited by the channels and are separated from each other.

For this purpose all

channels

6, 7, 8, 9, 10, 13a-13h are in fluid communication with each other to constitute a structure having protrusions or

islands

14a, 14b, 14c separated from each other by channels.

In this regard, the channels may be in fluid communication with each other to belong to a single set of channels, or two or more sets of channels may be provided, wherein each set of channels are in fluid communication with each other but not with the other sets of channels. Each set of channels is provided with at least one discharge opening or region, i.e. the sole comprises or defines at least one discharge opening in fluid communication with each set of channels. Thanks to this means, sweat that permeates or collects in the channels can flow into the set or sets of channels during the exercise until it flows to the

discharge openings

5a, 5 b.

If multiple sets of channels are provided, all

transverse channels

9, 10, 13a-13h may be terminal or intermediate in the above sense.

In the present invention, "fluid communication" means that the channels and the discharge openings (of the or each group of channels) are open towards each other at the respective end or connecting portion, or that they open into each other, so that sweat or water vapor collected or permeated into the channels can pass or flow between the channels and the discharge openings in fluid communication with each other, particularly during walking, running or sports activities, especially when the sole is assembled.

If desired, the plurality of channels comprises at least three main

longitudinal channels

It is clear that the indentations or recessed areas for receiving the anti-perforation insole may also be defined by the sole element or base element 3.

The anti-perforation insole 18 may also be co-molded with the midsole 4, for example, via thermoforming.

As an alternative, the anti-perforation insole 18 can be arranged on the mid-sole or top element 4, or in any case on the side opposite to the sole element or base element 3 with respect to the mid-sole or top element 4.

In non-work shoes, a puncture resistant insole is generally not required.

The base part 3 is preferably made of a material selected from the group comprising rubber, Thermoplastic Polyurethane (TPU), Polyurethane (PU), Ethylene Vinyl Acetate (EVA), thermoplastic rubber (TPR) or polyvinyl chloride (PVC) or mixtures thereof.

The top part 4 is preferably made of a material selected from the group comprising EVA, PU, TPR, TPU foam or PVC.

According to the present invention, there is also provided a shoe 2 comprising a sole 1 as described above and an upper 20 constrained to the top part 4 of the sole 1, in particular at the main inner surface 4c of the top part.

The shoe 2 then also comprises a mounting insole 21, for example made of breathable material, or suitably perforated, for example in an extension equal to or corresponding to the extension of said plurality of channels.

For this purpose, the upper 20 is mounted (for example glued) on a mounting insole 21, the unit thus obtained then being constrained to the sole 1, wherein the mounting insole 21 is next to the sole 1 or even better next to the main inner surface 4c of the main or mid-sole or top element 4.

In this regard, the mounting insole 21 is preferably adhered or contacted or glued peripherally to the major interior surface 4 c.

The mounting insole 21 ensures breathability or passage of perspiration or water vapour from the user's foot to the plurality of channels or channel structures defined by the sole.

In addition, in the upper 20, there may be extractable insoles or insoles, which constitute the abutment points of the user's foot or sock, also made of breathable material or suitably perforated.

As will be understood, the sole according to the present invention ensures, thanks to the particular plurality of channels, that the perspiration of the foot in the respective shoe is properly collected and conveyed towards the outside.

This is accomplished specifically during walking, running or athletic activities due to the movement of the shoe by the user's foot and the pressure exerted by the user's foot.

In addition, the tabs or stiffening ribs also improve the strength of the sole at the sweat removal area or opening.

The invention also provides a sole in which possible anti-perforation means can be integrated in a simple and quick manner, in particular an anti-perforation insole being arranged between the base part or sole part and the top part or midsole.

The invention is susceptible of modifications and variations within the scope of protection defined by the claims.
