Description

  The present invention relates to a front slip prevention pad and a female shoe with a built-in front slip prevention pad that do not cause a front slip even when a Japanese woman wears a western female shoe and does not impair the design of the western female shoe.

  Western women's shoes such as pumps and high heels worn by Westerners are popular with Japanese women due to their design and stability.

  However, many Japanese Egyptian toes have long toes (also called first toes). Conversely, Westerners often have a Greek type with a long second finger.

  In addition, the Japanese foot has a wide foot, a short middle foot, and a little rounded foot. On the contrary, the legs of Westerners are narrow, the middle leg is long, and the buttocks are rounded.

  For this reason, as shown in FIG. 7, when a Japanese woman with a short middle foot wears a Western women's pump 300, which is a kind of a shoe for women in the United States and Europe, a shoe designed to correspond to a long foot with a middle foot. The foot arch is not aligned with the arch corresponding part, the foot slips forward, the fingertips, that is, the gap between the heel of the foot and the heel end of the Western women's pump 300 is lost, and the fit is lost. As a result, the fingertips become painful and the skin of the heel of the foot is torn.

  For example, Japanese Patent Application Laid-Open No. H10-228561 is disclosed for preventing the above-mentioned front slip. The anti-slip insole of Patent Document 1 is formed of a material having a buffering effect, and has a protrusion sandwiched between the first finger of the foot and the second finger of the foot, and is placed on the foot of the shoe sole. Shape. The foot is placed on the front slip prevention insole, and the protrusion is sandwiched between the first finger of the foot and the second finger of the foot to prevent the front slip.

JP 2013-240644 A

  However, since the anti-slip insole of Patent Document 1 is placed on the insole of the insole of the shoe, the pad can be seen when the shoe is removed.

  For this reason, it was avoided to use it for expensive shoes. In particular, Western women's shoes are often avoided because they are expensive and often give up.

  Moreover, since patent document 1 prevents a front slip by the processus | protrusion pinched | interposed by the 1st finger of a foot and the 2nd finger of a foot, the crotch leg between a 1st finger and the 2nd finger of a foot hurts. There was a case.

  The present invention has been made to solve the above-mentioned problems, and prevents slipping when a Japanese woman wears Western women's standard shoes and can walk with the same fit as a Western woman. An object is to obtain a pad and a female shoe with a pad for preventing slipping.

In the present invention, the shoe is inserted between the insole (200) of the shoe (300) having a heel and the insole (200), and corresponds to the range from the root of the toe to the rear end of the arch.

(Detailed description of pad 100 for preventing slipping)
FIG. 4 is an explanatory diagram of the front slip prevention pad 100 of the present embodiment. FIG. 4A is a surface view of the front slip prevention pad 100. FIG. 4B is a side view when viewed from the II direction in FIG. FIG. 4C is a cross-sectional view taken along the line aa in FIG.

  As shown in FIG. 4A, FIG. 4B, and FIG. 4C, the front slip prevention pad 100 of the present embodiment includes a surface layer 100A (urethane sponge) and a drop-shaped convex portion 101. It is made into the multilayer structure which consists of convex part formation member 101A (urethane sponge: carbon is included) for forming.

  As shown in FIG. 4 (a), the front-slip prevention pad 100 of the present embodiment has a longitudinal length of about 150 mm (148 mm to 153 mm: preferably 150 mm) in a 23 cm type shoe, and the width of the front side edge 100a is as follows. It is about 70 mm (68 mm to 72 mm: preferably 70 mm), and the lateral width of the rear side edge 100 b is about 50 mm (48 mm to 52 mm: preferably 50 mm).

  In addition, an inner notch 103 corresponding to the inner tarsal bulbous region A is formed on the inner edge which is the inner side of the foot. The inner notch 103 has a width of about 46 mm (45 mm to 47 mm: preferably 46 mm), a rear depth of about 15 mm (14 mm to 16 mm: preferably 15 mm), and a front depth of about 10 mm (9 mm to 11 mm: Preferably it is 10 mm.

  Further, an outer notch 105 corresponding to the outer tarsal bulbous region B is formed on the outer edge which is the outer side of the foot. The outer notch 105 has a width of about 34 mm (33 mm to 35 mm: preferably 34 mm), a rear depth of about 20 mm (19 mm to 21 mm: preferably 20 mm), and a front depth of about 10 mm (9 mm to 11 mm: Preferably it is 10 mm.

  Further, the drop-shaped convex portion 101 has a width of about 38 mm (36 mm to 39 mm: preferably 38 mm) and a length of about 50 mm (49 mm to 51 mm: preferably 50 mm).

  As shown in FIG. 4B, when viewed from the II direction, the front slip prevention pad 100 of the present embodiment has a height from the bottom surface to the apex of the drop-shaped convex portion 101. It is about 12 mm (11 mm to 13 mm: preferably 12 mm).

  Then, as shown in FIGS. 4 (a) and 4 (b), a rear line Lf that is parallel to the rear edge 100b passes through a position f that is approximately near the rear side from the center of the drop-shaped convex portion 101. The thickness gradually decreases toward the side edge 100b.

  Further, the thickness gradually decreases from the front line Le connecting the substantially front side of the inner notch 103 and the substantially front side of the outer notch 105 toward the front edge 100a.

  The thickness between the front line Le and the rear line Lf is about 3 mm (2.9 mm to 3.1 mm: preferably 3 mm) as shown in FIG.

  That is, the raised portion of the arch portion of the sole is made thicker, and both end sides are made thinner gradually. For this reason, a feeling of fitting increases.

  Further, as shown in the aa cross-sectional view of FIG. 4C, the front slip prevention pad 100 is a multilayer composed of a urethane surface layer 100 </ b> A and a convex portion forming member 101 </ b> A for forming a drop-shaped convex portion 101. It is structured.

  And the back side of such a front slip prevention pad 100 is shown in FIG. As shown in FIG. 5, when the front slip prevention pad 100 is viewed from the back side, the convex portion forming member 101A has a bowl shape. This is because the two convex forming members 101A are connected to each other and separated by thermocompression molding with a mold on the back side of the surface layer 100A (for example, urethane sponge).

(Effect of using the front slip prevention pad 100)
In the case of the Western women's pump 300 in which the front slip prevention pad 100 as described above is pasted on the insole 150, when the Japanese woman wears it, the inner notch portion 103 causes the inner tarsal bulb region A of the sole to be worn. While pressing the insole 200, the outer sole sphere region B of the sole presses the insole 200 by the outer notch 105. For this reason, as shown in FIG. 6, there is no front slip, and there is no gap between the foot heel and the upper heel portion of the western women's pumps 300.

For this reason, Japanese women can walk with the same fit as Western women without causing slippage and pain without wearing Western women's pumps 300. In the above embodiment, the 23 cm type of shoes Although described as the front slip prevention pad 100, in the case of shoes of 24 cm, 25 cm,... That is, even if the shoe sizes are different, the inner notch 103 corresponding to the inner tarsal bulb region A is formed, and the outer notch 105 corresponding to the outer tarsal bulb region B is formed.
