Problems solved by technology

[0010] There are shoes with internal ventilation on the market, but the solutions currently used are structurally complex and functionally ineffective, so their actual use depends more on the advertising than on the actual effect in this regard

Embodiment Construction

[0022] Referring to Figures 1 and 2, it can be seen that the shoe sole (1) proposed by the present invention, like any conventional shoe sole, is made up of a single piece with standard parts corresponding to sole, arch and heel, especially with regard to figure 2 Outboard as shown, these portions may take on any number of surface finishes or configurations according to the design provided for the sole.

[0023] The invention focuses on the fact that the sole (1) comprises on its inner side a plurality of uniformly distributed longitudinal grooves (5) in the area corresponding to the sole of the foot, the number of which is five in the practical example given in the figures number, but this number can vary without affecting the essence of the invention, the grooves are preferably curved and parallel to the sides and next to the main body of the sole.

[0024] Said groove (5) on the upper side of the sole is supplemented with other lower grooves (5'), such as Figure 4 It can ...

Abstract

The invention relates to a self-ventilated, ergonomic footwear item and an elastomeric sole. According to the invention, both sides of the sole comprise a plurality of longitudinal grooves, in the area corresponding to the sole of the foot, which are essentially parallel to the edge of the sole closest thereto and which have a depth equal to half of the height of the sole. Moreover, the grooves are disposed in an alternating manner in relation to one another on either side of the sole in the form of a bellows-type structure. The upper comprises a perforated elastic laminar body which is disposed beneath the insole in the area corresponding to the sole of the foot and which, together with the sole, forms a chamber having a volume that varies upon walking. In addition, three thick bands aresolidly connected to the body and the upper in order to stiffen said elastic laminar body, namely: one longitudinal band and two transverse end bands. In this way, the footwear item and the sole adaptperfectly to the anatomy of the foot, enabling same to be automatically ventilated upon walking.

Description

[0001] purpose of invention [0002] The invention relates to a shoe and a sole comprising said shoe, but the sole is applicable to other types of shoes. On the one hand, the shoe offers optimum performance from a bioengineering point of view due to the elastic sole or the like usually formed by injection molding, which is then covered with the insole and combined with the corresponding upper to complete the shoe. The user's foot is adapted to the user's foot, regardless of the various relationships between the length and width of said foot, and on the other hand, the internal ventilation can be automatically generated when walking, and the comfort in this respect has been improved. [0003] Thus, the object of the present invention is to obtain a shoe that offers greater comfort to the user from the point of view of the comfortable fit of the foot and the breathability of the shoe, as well as an upper having a transversely highly elastic deformability in the area of ​​the sole ...
