Description

SHOE FOR HALLUS VALGUS
Description
This invention refers to a shoe. More specifically, it refers to a shoe that’s suitable for accommodating a foot with a bunion.
It is well known that those who suffer from bunions have a great deal of difficulty finding adequate shoes to wear. Those who suffer from this conditions usually choose to wear shoes that are at least one size greater than that which they could otherwise wear.
In recent years, various companies have sought to manufacture shoes specifically designed for feet with bunions. Besides being larger than the standard size, these shoes do not have any particular characteristics.
In these cases, the foot’s exceptional ability to adapt is being exploited; in fact, when these shoes are worn the user has an initial feeling of absolute wellness, since the foot is effectively accommodated inside a large space, but the use of a shoe with such characteristics can compromise normal walking, and in certain cases can even make the condition worse.
Moreover, shoes with these characteristics appear cumbersome or otherwise unpleasant from an aesthetic point of view.
The purpose of this invention is to overcome the aforementioned problems and others, by providing a shoe capable of accommodating a foot with a bunion in a comfortable yet stable manner.
Another purpose of the invention is to offer a shoe for feet with bunions that nevertheless has a pleasant look and an elegant appearance.
Another purpose of the invention is to offer a shoe for feet with bunions that allows for normal walking. These purposes and advantages are all achieved, according to the invention, by a shoe for feet with bunions that’s made with an enlarged toe, and has a shoe size, a length, and a width that are consistent with the shapes envisaged by the international standards.
In particular, the shoe made according to the invention is characterized by the fact that the toe size is equal to the toe size envisaged by the international standards, increased by a value equal to that which is obtained by multiplying the toe size envisaged by the international standard by a first coefficient X, between 8/17 and 10/17, preferably 9/17.
Thanks to this increased toe size, the shoe can be worn by people with toes affected by bunions, thus even ensuring greater comfort during use.
Advantageously, the shoe made according to the invention can have a shoe size equal to the shoe size envisaged by the international standards, increased by a value equal to that which is obtained by multiplying the shoe size envisaged by the international standard by a second coefficient Y, between 24/215 and 28/215, preferably 26/215.
An increase in the shoe size allows the shoe made according to the invention to be used normally by people with larger soles, arches and insteps, even considering the possibility of using an orthopedic insole.
Moreover, the shoe made according to the invention can have a length equal to the length envisaged by the international standards, increased by a value equal to that which is obtained by multiplying the length envisaged by the international standard by a third coefficient W, between 1/494 and 2/247, preferably 1/247.
A slight increase in the length of the shoe made according to the invention ensures its perfect adherence to the foot during walking. In fact, an excessive increase in length would result in difficulty using the shoe, as it would be rendered too large and therefore would not adhere to the foot.
Advantageously, the shoe made according to the invention can have a width equal to the width envisaged by the international standards, increased by a value equal to that which is obtained by multiplying the width envisaged by the international standard by a fourth coefficient Z, between 7/80 and 11/80, preferably 9/80.
An increase in the width of the sole allows the shoe made according to the invention to be used by people with altered and/or deformed foot soles by creating a perfect support surface, and even allows for the use of an orthopedic insole, thus ensuring optimal stability and proper shoe volume.
The shoe made according to the invention can also include an anatomical or corrective orthopedic insole, in order to further improve the shoe’s quality standards.
For exemplary and non-exhaustive purposes, the invention’s additional specifications and features are provided in greater detail within the description below, as well as within the attached diagrams, which include:
figures 1 through 4 are lateral schematic views of a shoe shape, with the toe size, the shoe size, the length, and the width respectively indicated in each.
A shoe made according to the known technique has shapes and shape references that are compliant with the international standards. In particular, the most important references include:
- the toe size, indicated in figure 1 with the reference“A”;
- the shoe size, indicated in figure 2 with the reference“C”;
- the length, indicated in figure 3 with the reference“Lu”; - the width, indicated in figure 4 with the reference“La”;
A shoe made according to the invention has a toe size, a shoe size, a length, and a width slightly greater than those envisaged by the international standards.
In fact, an increased toe size allows the shoe to be worn by people with toes affected by bunions, thus ensuring greater comfort during use.
An increase in the shoe size allows the shoe made according to the invention to be used normally by people with larger soles, arches and insteps, even considering the possibility of using an orthopedic insole.
A slight increase in the length of the shoe made according to the invention ensures its perfect adherence to the foot during walking. In fact, an excessive increase in length would result in difficulty using the shoe, as it would be rendered too large and therefore would not adhere to the foot.
An increase in the width of the sole allows the shoe made according to the invention to be used by people with altered and/or deformed foot soles by creating a perfect support surface, and even allows for the use of an orthopedic insole, thus ensuring optimal stability and proper shoe volume.
More specifically, the values of these four shoe shape references, according to the invention, are determined as defined below.
the toe size is increased by a value equal to that which is obtained by multiplying the toe size envisaged by the international standard by a first coefficient X, between 8/17 and 10/17, preferably 9/17.
the shoe size is increased by a value equal to that which is obtained by multiplying the shoe size envisaged by the international standard by a second coefficient Y, between 24/215 and 28/215, preferably 26/215.
the length is increased by a value equal to that which is obtained by multiplying the length envisaged by the international standard by a third coefficient W, between 1/494 and 2/247, preferably 1/247.
the width is increased by a value equal to that which is obtained by multiplying the width envisaged by the international standard by a fourth coefficient Z, between 7/80 and 11/80, preferably 9/80.
The increased toe size obtained using the first coefficient X, according to the invention, ensures a volume suitable for accommodating toes suffering from bunions, without compressing them.
The increased shoe size obtained using the second coefficient Y, according to the invention, allows the shoe to fit a foot with a large instep, while still ensuring perfect adherence to the upper.
An increased shoe length obtained using the third coefficient W, according to the invention, ensures the foot’s perfect adherence to the shoe.
Finally, the increased width of the sole obtained using the fourth coefficient Z, according to the invention, allows for and guarantees excellent and stable foot support, while still containing the foot within a proper size.
It should be noted that the coefficients defined above, and their relative ranges in particular, have been specifically researched and obtained. In fact, if values outside of these ranges were to be chosen, even by a small amount or for just one coefficient, the resulting balance would be altered.
For example, if the width of the shoe were to be increased beyond the previously defined values, the resulting shoe would not be aesthetically pleasing and would not adhere perfectly to the foot.
Similarly, an improper increase in shoe size would result in a shoe that does not adhere properly to the instep, thus preventing normal use. If the length of the shoe were to be increased beyond the previously defined values, the resulting shoe would tend to slip off the foot, thus preventing normal use.
And an increase in the width of the sole beyond the previously defined limits would result in instability while walking.
It should also be noted that, if the X, Y, W, and Z coefficients were to be altered beyond the previously defined limits, the resulting shoe would be poorly proportioned, unpleasant, and unsuitable for large-scale marketing.
Example 1
One design variant for the invention consists of a shoe with a shoe size of 37, with the following dimensions:
- a toe size of 26 mm instead of the 17 mm envisaged by the international standards;
- a shoe size of 241 mm instead of the 215 mm envisaged by the international standards;
- a length of 248 mm instead of the 247 mm envisaged by the international standards;
- a width of 89 mm instead of the 80 mm envisaged by the international standards.
The invention essentially provides a solution to the need for a shoe with a length that’s not much different than that of other normal shoes, but with a shoe size, sole and toe size volume greater than the international standard parameters, resulting in a toe volume capable of easily containing hammer toes, a very common affliction, while at the same time ensuring absolute stability and adherence during walking.
The shoe made according to the invention can also allow for the insertion of an anatomical or corrective orthopedic insole.
An industry technician may develop other possible variants, which are to be understood as covered within the scope of protection, as defined by the attached claims.
