Description

TECHNICAL FIELD The present invention relates to legwear worn on a foot, and more particularly to legwear that suppresses displacement and removal due to movement such as walking.

BACKGROUND ART Conventionally, legwear such as socks has been used for the purpose of preventing discomfort and tiredness and coldness when wearing shoes directly on bare feet. For example, when wearing shoes on legwear, friction occurs between the legwear and the shoes, and when the friction between the shoes and the legwear exceeds the friction between the feet and the legwear, the legwear moves. Instead of following the movement of the shoe, the legwear may slip or come off the foot. When wearing legwear, if the legwear shifts due to movement such as walking, it affects the wearing comfort, and thus there is a demand for legwear that is less likely to shift or come off. In particular, since the foot cover is configured to be hidden in the shoe when the shoe is put on, the area of the portion that covers the foot is small, and the foot cover is likely to slip off during wearing.

With regard to the prevention of such shifts and detachment of legwear, Patent Documents 1 to 6 propose legwear including various anti-slip portions inside the heel portion covering the heel.

For example, Patent Documents 1 and 2 propose legwear in which a belt-shaped non-slip portion is horizontally arranged inside the heel portion. Further, Patent Documents 3 and 4 propose legwear in which a plurality of protrusion-shaped or fragment-shaped non-slip portions are discontinuously arranged inside the heel portion. Further, Patent Documents 5 and 6 propose legwear in which a planar anti-slip portion is arranged inside the heel portion.

As one of the causes of slippage and dislodgement of the foot cover, the foot cloth of the heel part of the foot cover may be pulled forward due to contact and friction between the ground and the foot during movement such as walking, and the position of the anti-slip part may shift. Can be mentioned. That is, the non-slip portion arranged inside the heel cloth moves along with the expansion and contraction of the heel cloth. In addition, the walking mechanism includes not only the bending motion of the ankle in the vertical direction but also the motion in the lateral direction (valgus direction or varus direction), so that the fabric of the heel part is also stretched in the lateral direction. .. Therefore, the anti-slip portion cannot stay in a predetermined position, and a sufficient anti-slip effect cannot be obtained. As a result, the foot cover is easily displaced or removed.

However, in the above-mentioned conventional technique, since no consideration is given to the positional deviation of the anti-slip part due to the expansion and contraction of the fabric of the heel part, there is a problem that the anti-slip part cannot obtain a sufficient anti-slip effect.

For example, in the configurations of Patent Documents 1 and 2, since the band-shaped non-slip portions are arranged horizontally, the lateral expansion and contraction of the fabric of the heel part is suppressed, but the elastic expansion and contraction of the fabric of the heel part in the longitudinal direction. Cannot be suppressed. Therefore, in Patent Documents 1 and 2, the slippage of the slippage prevention portion in the vertical direction tends to occur, and a sufficient slippage prevention effect cannot be obtained.

Further, in the configurations of Patent Documents 3 and 4, since the protrusion-like or fragment-like non-slip portions are scattered and arranged, it is not possible to suppress the stretching of the fabric of the heel portion in the vertical direction and the horizontal direction. .. Therefore, in Patent Documents 3 and 4, the slip stoppers are likely to be displaced in the vertical and horizontal directions, and a sufficient slip preventing effect cannot be obtained.

Further, in the configurations of Patent Documents 5 and 6, since the planar anti-slip portion is arranged so as to cover the back surface of the heel, it is possible to suppress expansion and contraction of the fabric of the heel portion in the vertical direction and the horizontal direction. However, since the anti-slip part does not fit the heel and a gap is created, a sufficient anti-slip effect cannot be obtained. Further, in the configurations of Patent Documents 5 and 6, since the back surface of the heel is covered with the planar anti-slip portion, the skin is easily rashed by sweat or the like, and a new problem that the wearing comfort is deteriorated occurs.

The present invention has been made in view of the above problems of the related art, and an object thereof is to provide legwear that can favorably prevent slippage and removal without impairing the wearing comfort.

The legwear according to the present invention is provided with an elastic main body portion including at least a sole portion that covers the sole of the foot and a heel portion that covers the heel, and is provided inside the heel portion, and more than the fabric of the heel portion. A non-slip portion having low stretchability, the non-slip portion includes a plurality of strip-shaped portions extending in two or more different directions, and the strip-shaped portions have a shape in which the strip-shaped portions are combined in series. When the vertical direction is defined as a vertical direction, and the width direction of the sole is defined as a lateral direction, the anti-slip part includes, as the band-shaped part, a vertical band-shaped part that extends substantially linearly in the substantially vertical direction, By two sides that are in contact with both ends of the non-slip portion in the vertical direction and are parallel to the lateral direction, and two sides that are in contact with both ends of the anti-slip portion in the lateral direction and are parallel to the vertical direction. It is characterized in that the anti-slip portion is provided so that the calcaneal ridge of the calcaneus is included in the defined rectangular area.

Therefore, according to the present invention, there is an effect that it is possible to provide legwear capable of suitably suppressing slippage and removal without impairing the wearing comfort.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In the present embodiment, a case where the present invention is applied to a foot cover (leg wear) will be described as an example.

However, the present invention is not limited to a foot cover that exposes the instep and ankle, and can be applied to various legwear configured to cover the instep and ankle.

[Structure of foot cover 1]
FIG. 1 is a perspective view showing an external configuration of a foot cover 1 for a right foot according to this embodiment. As shown in FIG. 1, the foot cover 1 includes a main body portion 2 worn on the foot F, and a non-slip portion 3 that prevents the main body portion 2 from slipping off or coming off.

(Main body 2)
The main body 2 is formed of a sole 21 that covers the sole of the foot, a toe 22 that covers the toes, a side 23 that covers both sides of the foot F, and a heel 24 that covers the heel. Further, the main body portion 2 is provided with a shoe opening portion 2a for putting a foot in and out with respect to the sole 21 upside down.

The shoe opening 2a is largely opened so that the instep and the ankle are exposed, so that when the shoe is put on, the entire main body 2 is hidden in the shoe.

The main body 2 is made of a highly stretchable material, and preferably has good breathability and hygroscopicity. For example, natural fibers such as cotton, hemp, wool and silk, or rayon, nylon, acrylic. Chemical fibers such as polyester and polyester are preferable.

In the present embodiment, the main body 2 is knitted by a knitting machine, but it is also possible to form the main body 2 by sewing a cloth woven by a weaving machine.

(Slip prevention part 3)
The non-slip part 3 is a strip-shaped member made of a material having a lower elasticity than the cloth of the main body 2 and a higher friction coefficient than the cloth of the main body 2. The non-slip part 3 is provided inside the heel part 24, below the heels (outer malleolus and inner malleolus) and in the rear side region, and by contacting the heel, the main body part with respect to the foot F. Prevent slippage and removal of 2.

The material of the non-slip portion 3 is not particularly limited as long as it has a lower stretchability than the material of the main body 2 and a higher friction coefficient than the material of the main body 2. For example, various materials can be used in addition to a resin having a relatively large frictional resistance with the skin (natural resin such as natural rubber, synthetic resin such as silicon rubber or urethane rubber).

In addition, the anti-slip part 3 according to the present embodiment is formed into a sheet shape by pasting (applying) a resin or the like on the non-slip part forming material (base material), and pasting it on the heel part 24 of the main body part 2. It is attached. By thus forming the anti-slip part 3 in a sheet shape, it can be easily attached to the inside of the heel part 24 of the main body part 2, which is a three-dimensional curved surface.
The shape of the resin or the like attached to the non-slip part forming cloth does not have to match the shape of the non-slip part forming cloth, and may be an arbitrary pattern shape such as particles or floral patterns. Further, it is preferable to provide fine irregularities on the surface of resin or the like to increase the friction coefficient.

The non-slip part forming material (base material) is preferably a material having a certain elasticity. By using a material having a certain elasticity as a base material, the fabric of the heel portion 24 can be directly applied to the fabric of the heel portion 24 (main body portion 2) without preventing the fabric itself from properly fitting the heel shape. It is possible to more effectively suppress the expansion and contraction of the fabric of the heel portion 24 in the longitudinal direction and the lateral direction, as compared with the case where the material is attached.

Further, it is preferable that the non-slip part forming material (base material) is a material having unevenness. For example, when a knitted fabric or a woven fabric has irregularities in stitches or weaves, it is possible to easily form fine irregularities on the surface of the resin or the like by thinly applying a resin or the like to increase the friction coefficient.

It should be noted that it is also possible to directly apply or stick resin or the like onto the cloth of the heel portion 24 of the main body 2.

FIG. 2 is a schematic view for explaining the shape of the anti-skid portion 3 shown in FIG. 1, (a) of FIG. 2 is a rear view of the anti-slip portion 3, and (b) of FIG. [Fig. 3] is a side view of the anti-slip part 3. In FIG. 2A, the Achilles tendon A is omitted.

As shown in (a) of FIG. 2 and (b) of FIG. 2, the anti-slip portion 3 has a vertical direction (x direction in the drawing) in a direction perpendicular to the sole 21 and a width direction of the sole 21. Is defined as the lateral direction (the y direction in the drawing), it is a shape in which a plurality of band-shaped portions extending in different directions are combined so as to suppress the expansion and contraction of the fabric of the heel portion 24 in the longitudinal direction and the lateral direction. (In the figure, the direction from the heel to the toe is shown as the z direction.).

Specifically, the anti-slip part 3 includes a horizontal strip-shaped portion (first strip-shaped portion) 31 that extends in a substantially lateral direction across the Achilles tendon A, and two vertical strip-shaped portions (second strip-shaped portion) that extend in a substantially vertical direction. Strip-shaped portions) 32a and 32b, and the two vertical strip-shaped portions 32a and 32b are provided so as to sandwich the calcaneus B (or the calcaneal ridge C). In addition, in this embodiment, the two vertical strips 32a and 32b are arranged so as to have a slight angle difference with respect to the vertical direction such that the interval gradually widens as they approach the sole 21.

In this way, by combining the horizontal strip-shaped portion 31 and the two vertical strip-shaped portions 32a and 32b into a substantially U-shape that is open to the sole 21 side, the fabric of the heel portion 24 can be extended in the vertical and horizontal directions. Expansion and contraction can be suppressed.

It should be noted that two sides that are in contact with both ends of the slip stopper 3 in the vertical direction (that is, the upper end of the horizontal strip 31 and the lower ends of the vertical strips 32a and 32b) and that are parallel to the horizontal direction, Within a rectangular region R defined by two sides that are in contact with both ends (that is, the left end of the vertical strip 32a and the right end of the vertical strip 32b) of the non-slip part 3 in FIG. It is preferable that the non-slip portion 3 is provided so as to include the central portion of the back surface of the calcaneus B (for example, the calcaneal ridge C). As a result, it is possible to preferably suppress the expansion and contraction in the vertical direction and the horizontal direction of the part of the heel portion 24 where the fabric is particularly easy to move.

Further, as in the present embodiment, the anti-slip portion 3 is formed in a series by connecting the horizontal strip portion 31 and the vertical strip portion 32a, and the horizontal strip portion 31 and the vertical strip portion 32b, respectively. Is preferred. As a result, partial slippage of the slip-prevention portion 3 is unlikely to occur, so that the expansion and contraction of the fabric of the heel portion 24 in the vertical direction and the horizontal direction can be suppressed more effectively.

[Effect of foot cover 1]
When walking, particularly when the fabric of the heel portion 24 does not follow the movement of the vicinity of the Achilles tendon A, the fabric of the heel portion 24 is pulled in the longitudinal direction. Further, the walking mechanism includes not only the bending motion of the ankle in the vertical direction but also the motion in the lateral direction (valgus direction or varus direction), so that the fabric of the heel portion 24 is pulled in the lateral direction. It Therefore, by suppressing only one of the expansion and contraction of the fabric of the heel portion 24 in the vertical direction or the expansion and contraction of the fabric of the heel portion 24 in the lateral direction, the slip prevention portion due to the expansion and contraction of the fabric of the heel portion 24 is prevented. The position shift cannot be suppressed.

Therefore, in the foot cover 1, the horizontal strip-shaped portion 31 and the two vertical strip-shaped portions 32a and 32b are opened to the sole 21 side so as to suppress the expansion and contraction of the fabric of the heel 24 in the vertical and horizontal directions. It is combined in a roughly U shape.

In the foot cover 1, a horizontal strip portion 31 is provided above the portion, a vertical strip portion 32a is provided on the left side, and a vertical strip portion 32a is provided on the right side so as to surround a portion of the heel portion 24 where the fabric is particularly easy to move (a rear center portion of the calcaneus B). A mold strip 32b is provided. Therefore, the anti-slip part 3 can suitably suppress the expansion and contraction of the fabric of the heel part 24 in the vertical direction and the horizontal direction.

Further, since the body portion 2 is formed of a highly stretchable material, the material itself of the heel portion 24 fits the heel shape appropriately. Therefore, the foot cover 1 does not follow the movement of shoes or the like and is displaced, and a sufficient anti-slip effect can be obtained.

Further, since the anti-slip part 3 has a shape in which a plurality of strip-shaped parts are connected in series, the anti-slip part 3 easily fits on the heel and a sufficient anti-slip effect can be obtained, and also sufficient air permeability is secured. It is possible to prevent skin irritation due to sweat.

It is known that the shape of the heel boat around the foot through the heel and instep does not change much during walking. Therefore, even if the expansion and contraction of the fabric of the heel portion 24 is suppressed by the anti-slip portion 3, discomfort during wearing is unlikely to occur. On the other hand, for example, the sole 21 (such as the width of the middle foot) expands and contracts due to the extension of the arch of the sole of the foot. Therefore, suppressing expansion and contraction of the fabric of the sole 21 tends to cause discomfort during wearing. As described above, by providing the anti-slip portion 3 on the heel portion 24, it is possible to prevent the comfort of the foot cover 1 from being deteriorated.

Therefore, according to the present embodiment, it is possible to realize the foot cover 1 capable of appropriately suppressing the slippage and the detachment without impairing the wearing comfort.

[Modification 1]
FIG. 3A to FIG. 3M are rear views showing modified examples of the antiskid portion 3 according to the present embodiment.

The anti-slip part 3 is not limited to the above-mentioned shape as long as it can suppress the expansion and contraction of the fabric of the heel part 24 in the vertical direction and the horizontal direction.

For example, as shown in (a) of FIG. 3, the anti-slip part 3 has a substantially H-shaped configuration in which a horizontal strip portion 31 is provided so as to connect the central portions of the two vertical strip portions 32a and 32b. It may have a shape.

Further, as shown in FIG. 3B, the non-slip portion 3 has a substantially T-shaped shape in which the center portion of the horizontal strip portion 31 is connected to the upper end portion of the vertical strip portion 32c extending in the vertical direction. May be Alternatively, as shown in (c) of FIG. 3, the anti-slip portion 3 has an inverted T-shape in which the central portion of the horizontal strip portion 31 is connected to the lower end portion of the vertical strip portion 32c extending in the vertical direction. The shape may be.

Further, as shown in (d) of FIG. 3, in the anti-slip part 3, the lower ends of the two vertical strip portions 32c and 32d that are substantially parallel to each other and extend in the substantially vertical direction are connected to each other by the horizontal strip portion 31. The shape may be a substantially U-shape that is open to the side of the shoe opening 2a.

As shown in (e) of FIG. 3, the anti-slip part 3 has a horizontal strip shape in which the upper ends of two vertical strip portions 32c and 32d which are substantially parallel to each other and which extend in the vertical direction, have upper end portions extending in a substantially horizontal direction. The shape may be a substantially square shape in which the vertical strip portions 32c and 32d are connected by the portion 31a and the lower end portions of the vertical strip portions 32c and 32d are connected by the horizontal strip portion 31b.

Further, as shown in (f) of FIG. 3, the anti-slip part 3 includes two diagonal band-shaped parts (third band-shaped parts) 33a and 33b extending in an oblique direction different from the substantially vertical direction and the substantially horizontal direction. In addition, the oblique band-shaped portions 33a and 33b may have a substantially X-shaped shape where they intersect each other at the center.

Further, as shown in (g) of FIG. 3, the non-slip portion 3 has a substantially V-shaped shape in which the lower end of the diagonal strip 33a and the lower end of the diagonal strip 33b intersect. Good. Alternatively, as shown in (h) of FIG. 3, the anti-slip part 3 has an inverted V-shaped shape in which the upper end of the diagonal strip 33a and the upper end of the diagonal strip 33b intersect. Good.

Further, as shown in (i) of FIG. 3, the anti-slip portion 3 has two vertical strip-shaped portions 32c and 32d extending substantially in the vertical direction and having upper ends that are substantially V-shaped. It may have a substantially M-shaped shape connected by the oblique band portions 33a and 33b.

In addition, as shown in (i) of FIG. 3 and (k) of FIG. 3, in the anti-slip part 3, a curvilinear curvilinear band-shaped part (fourth band-shaped part) 34 is formed in a central part of the back surface of the calcaneus B (for example, , May be curved so as to surround the calcaneus ridge C).

Further, as shown in (l) of FIG. 3 and (m) of FIG. 3, the non-slip portion 3 includes two curved strip portions 34a and 34b intersecting with each other, and the curved strip portions 34a and 34b have heels. It may be arranged so as to surround a central part of the back surface of the bone B (for example, a calcaneal protuberance C).

3A to 3M, the back surface central portion of the calcaneus B (for example, the calcaneal ridge C) is arranged at the center of the rectangular region R. Thus, it is preferable to provide the anti-slip part 3. As a result, expansion and contraction of the heel portion 24 in the vertical direction and the horizontal direction can be appropriately suppressed, and positional deviation of the anti-slip portion 3 can be suppressed.

The anti-slip part 3 is not limited to these shapes. The non-slip portion 3 is a horizontal strip portion 31, 31a, 31b, a vertical strip portion 32a, 32b, 32c, 32d, a diagonal strip portion so that the fabric of the heel portion 24 can be restrained from stretching in the vertical and horizontal directions. The shape may be a combination of the strip portions 33a and 33b and the curved strip portion 34 as appropriate.

[Modification 2]
FIG. 4 is a rear view showing another modified example of the slip stopper 3 according to the present embodiment. As shown in FIG. 4, in the anti-slip part 3, the horizontal strip-shaped portion 31 and the vertical strip-shaped portion 32a, and the horizontal strip-shaped portion 31 and the vertical strip-shaped portion 32b are not necessarily connected.

Even with such a shape, the lateral strip portion 31 can suppress the lateral expansion and contraction of the fabric of the heel portion due to the lateral motion of the ankle (valgus direction or varus direction). Further, the vertical strip portions 32a and 32b can prevent the fabric of the heel portion 24 from expanding and contracting in the vertical direction due to the bending motion of the ankle in the vertical direction.

However, since the horizontal strip-shaped portion 31 and the vertical strip-shaped portion 32a and the horizontal strip-shaped portion 31 and the vertical strip-shaped portion 32b are connected and formed in series, a partial positional deviation of the anti-slip portion 3 is less likely to occur. .. Therefore, by connecting the horizontal strip-shaped portion 31 and the vertical strip-shaped portion 32a, and the horizontal strip-shaped portion 31 and the vertical strip-shaped portion 32b, it is possible to effectively suppress the stretching of the fabric of the heel portion 24 in the vertical direction and the horizontal direction. It is preferable because it can be

The present invention is not limited to the above-described embodiments, but various modifications can be made within the scope of the claims, and embodiments obtained by appropriately combining the technical means disclosed in the different embodiments Is also included in the technical scope of the present invention.

An embodiment of the present invention will be described below with reference to FIGS. In this example, the anti-slip effect of the legwear according to the present invention was verified.

5(a) to 5(f) are rear views showing the shapes of the respective anti-slip portions tested in this example. As shown in FIGS. 5(a) and 5(b), in the present embodiment, as the anti-slip part of the present invention, the anti-slip part having a substantially U-shape opening to the sole 21 side. 3a and the non-slip part 3b were prepared. The difference between the non-slip portion 3a and the non-slip portion 3b is that the two vertical strip portions 32a' and 32b' of the non-slip portion 3b are larger than the widths of the two vertical strip portions 32a and 32b of the non-slip portion 3a. The point is that the width of the.

Further, as shown in (c) to (f) of FIG. 5, as a comparison target, the horizontal strip-shaped portion 31 is removed from the slip-preventing portion 3a, and the non-slip portion 103a configured by the vertical strip-shaped portions 32a and 32b. A non-slip portion 103b composed of a vertical strip portion 32c extending in a substantially vertical direction, a non-slip portion 103c formed of a horizontal strip portion 31c extending in a substantially horizontal direction, and a horizontal strip portion wider than the horizontal strip portion 31c. Each of the non-slip portions 103d composed of 31d was prepared,
〔Test method〕
FIG. 6 is a schematic diagram for explaining the test method of this example.

(2) Each sample was measured 5 times, and the average value of the tensile force when the foot cover was removed was calculated.

〔Test results〕

Table 1 is a table showing the test results of this example. FIG. 7 is a graph showing the test results of this example, and FIG. 7A shows the test results when a female standard foot mannequin is put on a foot cover provided with each anti-slip portion. Yes, FIG. 7(b) shows the test results when the female standard foot mannequin was put on the pantyhose and the foot cover provided with each anti-slip portion was put on, and FIG. 7(c) is It is a test result when a foot cover in which each anti-slip portion is provided is put on the raw foot.

In Table 1 and FIGS. 7(a) to 7(c), the foot cover provided with the anti-slip portion 3a is the first embodiment, and the foot cover provided with the anti-slip portion 3b is the second embodiment. The foot cover provided with the portion 103a is Comparative Example 1, the foot cover provided with the anti-slip portion 103b is Comparative Example 2, the foot cover provided with the anti-slip portion 103c is Comparative Example 3, and the foot cover provided with the anti-slip portion 103d is provided. This is shown as Comparative Example 4. The numerical value in parentheses in Table 1 is a value obtained by dividing the tensile force (N/mm ² ) by the area (mm ² ) of the non-slip portion, and indicates the anti-slip force per unit area of each anti-slip portion. It is an index.

As shown in Table 1 and (a) of FIG. 7, when a foot cover provided with each non-slip portion is put on a female standard foot mannequin, the foot cover of Example 1 and the foot cover of Example 2 are Even if the foot cover fabric was pulled to the limit value that it could withstand, the foot cover was never removed.

On the other hand, the average value of the tensile force when the foot cover of Comparative Example 1 was removed was 0.51±0.03, and the average value of the tensile force when the foot cover of Comparative Example 2 was removed was 0.46. ±0.03, the average value of the tensile force when the foot cover of Comparative Example 3 was removed was 0.57±0.02, and the average value of the tensile force when the foot cover of Comparative Example 4 was removed was 1.51. It was ±0.02.

Further, as shown in Table 1 and FIG. 7B, when the female standard foot type mannequin is fitted with a pantyhose and a foot cover provided with each anti-slip portion is put on, the foot cover of Example 1 is The average value of the tensile force when the foot cover was removed was 2.59±0.22, and the average value of the tensile force when the foot cover of Example 2 was removed was 2.53±0.03.

On the other hand, the average value of the tensile force when the foot cover of Comparative Example 1 was removed was 0.56±0.02, and the average value of the tensile force when the foot cover of Comparative Example 2 was removed was 0.60. ±0.01, the average value of tensile force when the foot cover of Comparative Example 3 was removed was 0.64±0.03, and the average value of tensile force when the foot cover of Comparative Example 4 was removed was 1.08. It was ±0.03.

Further, as shown in Table 1 and FIG. 7(c), when the foot cover provided with each anti-slip portion is put on the raw foot, the average value of the tensile force when the foot cover of Example 1 is removed Was 2.94±0.09, and the average value of the tensile force when the foot cover of Example 2 was removed was 2.60±0.09.

On the other hand, the average value of the tensile force when the foot cover of Comparative Example 1 was removed was 0.38±0.01, and the average value of the tensile force when the foot cover of Comparative Example 2 was removed was 0.37. ±0.03, the average value of tensile force when the foot cover of Comparative Example 3 was removed was 0.42±0.01, and the average value of tensile force when the foot cover of Comparative Example 4 was removed was 0.74. It was ±0.02.

In this way, when the female standard foot mannequin is fitted with a foot cover provided with each anti-slip part, the female standard foot mannequin is fitted with pantyhose and the foot cover provided with each anti-slip part is also worn. In each case, the foot covers of Examples 1 and 2 were the same as those of Comparative Examples 1 to 4 in any case where the foot cover provided with each anti-slip portion was put on the raw foot. It was harder to take off, and a high anti-slip effect was obtained.

This is because in the foot covers of the first and second embodiments, the lateral strip 31 and the vertical strips 32a and 32b, or the horizontal strip 31 and the vertical strips 32a' and 32b' of the heel portion 24 are used. This is because, as a result of suppressing expansion and contraction of the fabric in the longitudinal direction and the lateral direction, positional deviation of the anti-slip part due to expansion and contraction of the fabric of the heel portion 24 is suppressed, and a sufficient anti-slip effect by the anti-slip part is obtained. ..

On the other hand, in the foot covers of Comparative Examples 1 to 4, the fabric of the heel portion 24 expands or contracts in the vertical direction or the horizontal direction. For example, in the foot cover of Comparative Example 1, since the two vertical strip portions 32a and 32b of the anti-slip portion 103a are not connected, the fabric of the heel portion 24 expands and contracts in the lateral direction. For this reason, in the foot covers of Comparative Examples 1 to 4, the slippage of the fabric of the heel portion 24 was displaced due to the expansion and contraction of the fabric, and the slippage prevention effect was not obtained sufficiently.

As described above, in this example, it was confirmed that the legwear according to the present invention provided a high anti-slip effect.

[Supplement]
The present invention can also be expressed as follows.
