Benefits of technology

The invention is a way to improve a shoe by making it more comfortable, efficient, and responsive. This is done by using an intermediate component that can compress and release, which helps to disperse and dampen forces. This makes the shoe easier to wear and reduces fatigue. The method also improves the structure of the shoe, making it more precise and comfortable during use. This invention helps to optimize the performance and comfort of shoes for different uses.

Problems solved by technology

The main problem with a shoe is in assembling and turning components that are cut and assembled flat into a three-dimensional shape.
Such a large number of shoe-forming components increases the number of manufacturing operations and the time required to carry out such operations.
It can be said that shoes manufactured using conventional techniques are complicated, both by the number of their components and the number of manufacturing operations.
Another disadvantage results from the structure discontinuity of the shoe, in particular in the area of the upper.
This may hinder a user and also render the shaping, i.e., three-dimensional shaping, of the upper more difficult.
A further disadvantage is due to the presence of free spaces between the foot and the shoe.
As a result, undesired displacements occur sometimes between the foot and the shoe, which can cause discomfort or injuries.
Consequently, undesired foreign bodies may penetrate into the shoe.
Finally, it can be said that a shoe according to the prior art does not always ensure adequate support and / or tightening of the foot, or does not always provide satisfactory comfort for the foot.
Moreover, this shoe does not systematically conform to all of the foot deformations.
This is a real challenge when support or transmission of intense information is desired, for example during a sporting activity.

first embodiment

[0035]The first embodiment is described below with reference to FIGS. 1 to 10.

[0036]As shown in FIGS. 1 and 2, an article of footwear 1 is provided to receive the foot of the user. For convenience, the article of footwear 1 will be considered as a shoe in the following description although, as shown in detail below, its structure is completely unusual. Thus, the shoe 1 extends lengthwise along a longitudinal direction L, between a rear end or heel 4 and a front end or tip 5, and widthwise along a transverse direction W, between a lateral side 6 and a medial side 7.

[0037]As shown, the upper of the shoe 1 comprises a lower portion 10, provided to surround the foot, and has no upper portion. Alternatively, however, a shoe may be envisioned to include both a lower portion and an upper portion, the latter being provided to surround the ankle and possibly the lower leg.

[0038]According to the first embodiment described, the shoe 1 extends heightwise from a bottom 12 to a top end 13, that i...

second embodiment

[0074]Thus, the second embodiment, according to FIG. 11, comprises an article of footwear or shoe 1 with a lateral side 6 and a medial side 7, and a bottom 12 and a top end 13. The first envelope 21, the second envelope 31, the reinforcement 51, the keepers 62, and the tongue 71 are also reprised.

[0075]What is specific to the second embodiment is that it comprises another intermediate component 101 arranged between the two envelopes 21, 31. This intermediate component 101 is a portion of a sole assembly 102, the sole assembly portion being located in the area of the bottoms 28, 38 of the first 21 and second 31 envelopes, the portion 101 of the sole assembly 102 extending lengthwise from a rear end 104 to a front end 105, widthwise between a lateral side 106 and a medial side 107, and depthwise between a bottom 108 and a top 109. The portion 101 enables a relative displacement of the portions of the envelopes that are opposite thereto. In this case, it is the entirety or subdivisions...

third embodiment

[0081]In a non-limiting manner, according to this third embodiment of the invention, the intermediate component, namely the portion 121 of the sole assembly 122, extends opposite the entirety of the bottoms 28, 38 of the first 21 and second 31 envelopes. This makes it possible to obtain a damping effect in the area of the entire bottom 12 of the article of footwear.

[0082]The intermediate component 121 is for example affixed to the first envelope 21 and / or to the second envelope 31. It is affixed by any suitable means such as gluing, or any equivalent or complementary technique. This optimizes cooperation between the bottoms 28, 38 of the envelopes 21, 31, in terms of a more precise transmission of the forces or sensory information. However, one may alternatively provide to arrange the intermediate component without affixation to the bottoms.

[0083]To fulfill its role under the best conditions, the intermediate component 121 comprises a layer of elastically deformable synthetic materi...

Abstract

An article of footwear that includes a first envelope extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and heightwise from a bottom to a top end, the first envelope demarcating a volume for receiving a foot, the article of footwear including a second envelope extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and heightwise from a bottom to a top end, the second envelope demarcating a volume for receiving a foot, the first envelope and the second envelope being arranged opposite one another. In the area of at least one subdivision, the article of footwear includes an intermediate component deformable elastically and reversibly, the intermediate component being arranged between the first envelope and the second envelope.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The invention relates to an article of footwear, such as a shoe or any equivalent. The article of footwear can be used in fields such as walking, running on flat or mountainous terrain, skateboarding, ball-playing sports, cross-country skiing, snowboarding, snowshoeing, biking, and the like.[0003]2. Description of the Background[0004]An article of footwear must fulfill various and sometimes contradictory functions, such as providing adequate support and / or tightening of the foot while providing satisfactory comfort for the foot. The article of footwear must also have a certain flexibility, a property that involves good deformability to certain deformations of the foot. In other words, the article of footwear must adapt to the foot while allowing it to have the freedom required for walking or practicing the sport involved.[0005]To this end, it is known to make articles of footwear, such as shoes, by combining an upper and a sole assembly...
