Description

The present invention relates to slippers and a method for putting on slippers, and more particularly to slippers that are difficult to come off and a method for putting on slippers.

Slippers are footwear that you can slip your feet into easily. Slippers consist of a bottom part with a semicircular tip and an instep part that is attached to the bottom part and covers the instep of the foot (see, for example, Patent Document 1).

Utility Model Registration No. 3219574

However, while slippers are easy to put on, they have the problem of being easy to slip off.

An object of the present invention is to provide slippers and a method for putting on slippers that take the above problems into consideration.

The slippers according to claim 1 are slippers comprising an outer sole, a midsole located on the outer sole, an upper extending around the entire periphery of the outer sole and covering the instep of the foot, and an insole abutting on the upper surface of the midsole, wherein the toe side of the insole and the heel side of the insole abut on the back surface of the upper, and the toe side of the insole and the heel side of the insole form convex portions that are upwardly convex, and at least during the swing phase of walking, the sole of the foot abuts on the convex portions and the instep abuts on the back surface of the upper due to the elastic force of the convex portions.

The method of wearing slippers described in claim 2 is a slipper comprising an outer sole, a midsole positioned on top of the outer sole, an upper that stands around the entire circumference of the outer sole and covers the instep of the foot, and an insole that abuts against the upper surface of the midsole, wherein the toe side of the insole and the heel side of the insole abut against the underside of the upper, and the toe side of the insole and the middle of the heel side of the insole form a convex portion that is upwardly convex, and at least during the swing phase of walking, the sole of the foot abuts against the convex portion, and the instep of the foot abuts against the underside of the upper due to the elastic force of the convex portion.

In addition, the slippers described in claim 3 are slippers comprising an outsole, a midsole positioned on top of this sole, an upper that stands around the entire circumference of the outsole and covers the instep of the foot, and an insole that abuts against the upper surface of the midsole, wherein the toe side of the insole and the heel side of the insole abut against the back surface of the upper, and the toe side of the insole and the middle of the heel side of the insole form a convex portion that is upwardly convex, and at least during the swing phase of walking, the sole of the foot abuts against the convex portion, and the instep of the foot abuts against the back surface of the upper due to the elastic force of the convex portion.

The method of wearing slippers described in claim 4 is a slipper comprising an outer sole, a midsole located on top of the outer sole, an upper that stands around the entire circumference of the outer sole and covers the instep of the foot, and an insole that abuts against the upper surface of the midsole, wherein the toe side of the insole and the heel side of the insole abut against the underside of the upper, and the toe side of the insole and the middle of the heel side of the insole form a convex portion that is upwardly convex, and at least during the swing phase of walking, the sole of the foot abuts against the convex portion, and the instep of the foot abuts against the underside of the upper due to the elastic force of the convex portion.

According to the slippers of claim 1, the toe side of the insole and the heel side of the insole are in contact with the back surface of the upper, and the toe side of the insole and the heel side of the insole form a convex portion that is convex upwards in the middle. At least, when walking, the instep of the foot is in contact with the back surface of the upper due to the elastic force of the convex portion, so that the slippers are difficult to slip off.
In addition, the toe side (tip) and heel side (rear end) of the insole are in contact with the underside of the upper, restricting the horizontal movement of the insole, and the rebound force of the convex part is also large, making it even more difficult to slip off.
Furthermore, since the area on the back side of the convex portion of the insole is separated from the midsole, the convex portion of the insole changes significantly in the vertical direction, stimulating the area near the arch of the foot with the convex portion and increasing the massage effect. In addition, since the horizontal movement of the insole is restricted, the rebound force of the convex portion is also greater, further increasing the massage effect.

According to the method of wearing slippers described in claim 2, the toe side of the insole and the heel side of the insole are in contact with the back surface of the upper, and the toe side of the insole and the heel side of the insole form a convex portion that is convex upwards in the middle. At least, when walking, the instep of the foot is in contact with the back surface of the upper due to the elastic force of the convex portion, so that the slippers are difficult to slip off.
In addition, the toe side (tip) and heel side (rear end) of the insole are in contact with the underside of the upper, restricting the horizontal movement of the insole, and the rebound force of the convex part is also large, making it even more difficult to slip off.
Furthermore, since the area on the back side of the convex portion of the insole is separated from the midsole, the convex portion of the insole changes significantly in the vertical direction, stimulating the area near the arch of the foot with the convex portion and increasing the massage effect. In addition, since the horizontal movement of the insole is restricted, the rebound force of the convex portion is also greater, further increasing the massage effect.

An embodiment of footwear (e.g., slippers) and a method of wearing footwear (e.g., a method of wearing slippers) according to the present invention will be described with reference to the drawings (Figs. 1 to 7).

The symbol S in FIG. 1 denotes footwear (e.g., slippers). The footwear (e.g., slippers) S comprises an outer sole 1, a midsole 2 positioned on the outer sole 1, an upper 3 standing around the entire periphery of the outer sole 1 and covering the instep of the foot, and an insole 4 abutting on the upper surface of the midsole 2.
The outsole 1, the midsole 2 and the upper 3 are integrated together by sewing, bonding or the like.

The insole 4 is formed of an elastic member (such as polyurethane, EVA, rubber, or an elastic material), and as shown in FIG. 6, the toe side (tip) 4X and the heel side (rear end) 4Y of the insole 4 abut against the underside of the upper 3, and the midpoints of the toe side (tip) 4X and the heel side (rear end) 4Y of the insole 4 form a convex portion 4T that is upwardly convex, and at least when walking, the elastic force of the convex portion 4T causes the instep to abut against the underside of the upper 3, as shown in FIG.
That is, when standing as shown in FIG. 6 (when putting on or taking off shoes, or when working while standing), weight is applied and the insole 4 sinks, creating a gap between the instep of the foot and the instep of the footwear (e.g., slippers), making it possible to put on and take off the footwear (e.g., slippers) smoothly, and since pressure on the instep is reduced when standing, there is a feeling of openness and it is also effective in preventing stuffiness.
In addition, when walking (off the ground) as shown in FIG. 7, the elastic force of the insole 4 lifts the foot, and the instep of the foot fits snugly to the instep of the footwear (e.g., slippers), making it difficult for the footwear (e.g., slippers) to slip off.
The thickness of the convex portion 4T is, for example, 1 mm to 20 mm, and the distance between the rear side of the convex portion 4T and the insole 2 is, for example, 1 mm to 40 mm.

According to the above-mentioned footwear (e.g., slippers) and footwear wearing method (e.g., a method for wearing slippers), the toe side and heel side of the insole 4 abut against the underside of the upper 3, and the midpoint between the toe side 4X of the insole 4 and the heel side 4Y of the insole 4 forms a convex portion 4T that is upwardly convex, and at least when walking, the instep of the foot abuts against the underside of the upper 3 due to the elastic force of the convex portion 4T, making it difficult for the footwear to slip off,
Moreover, the toe side (tip) 4X and the heel side (rear end) 4Y of the insole 4 come into contact with the back surface of the upper 3, restricting the horizontal movement of the insole 4, and the repulsive force of the convex portion 4T is increased, making it even more difficult for the insole 4 to slip off.
Furthermore, since the area on the back side of the convex portion 4T of the insole 4 is separated from the midsole 2, the convex portion 4T of the insole 4 changes greatly in the vertical direction, stimulating the area near the arch of the foot with the convex portion 4T, thereby increasing the massage effect.
In addition, since the horizontal movement of the insole 4 is restricted, the repulsive force of the convex portion 4T is increased, and the massage effect can be further increased.

In this embodiment, as shown in FIG. 2, the insole 4 has a convex shape 4T that is convex upwards at the midpoint between the toe side (tip) 4X and the heel side (rear end) 4Y of the insole 4 before it is fitted into the upper 3, but the present invention is not limited to this, and can also be applied to a case (not shown) where the insole is straight before it is fitted into the upper 3 and the overall length of the insole is longer than the overall length from the tip to the rear end of the upper 3, and where the insole is fitted into the upper 3 and the midpoint between the toe side (tip) and the heel side (rear end) of the insole are convex upwards.

In this embodiment, slippers are used as an example, but the present invention is not limited to slippers and can be applied to sandals, short shoes, and other footwear in the same way.

Although the insole 4 is used in the above embodiment, the present invention can be similarly applied to footwear S' that does not have the insole 4.
That is, as shown in Figures 8 to 12, footwear (e.g., sandals) S' comprises an outsole 1, a midsole 2 positioned on top of the outsole 1, and an upper 3 that stands around the entire circumference of the outsole 1 and covers the instep of the foot.
The midpoint between the toe side (tip) 2X of the insole 2 and the heel side (rear end) 2Y of the insole 2 forms a convex portion 2T that is convex upward, and the portion of the outsole 1 that corresponds to the convex portion 2T forms a concave portion 1H that is concave downward, so that at least when walking, the elastic force of the convex portion 2T causes the instep of the foot to abut against the underside of the upper 3.
Although the upper 3 is erected around the entire periphery of the outsole 1 and is designed to cover the instep of the foot, the present invention is not limited to this, and the upper 3 may simply cover the instep of the foot.

According to the footwear (e.g., sandals) S' and the method of wearing the footwear, the midpoint between the toe side (front end) 2X of the insole 2 and the heel side (rear end) 2Y of the insole 2 forms a convex portion 2T that is upwardly convex, and the portion of the outsole 1 that corresponds to the convex portion 2T forms a concave portion 1H that is downwardly concave, and at least when walking, the instep of the foot abuts against the back surface of the upper 3 due to the elastic force of the convex portion 2T, so that the footwear is unlikely to slip off,
Furthermore, since the portion of the sole 1 corresponding to the convex portion 2T forms a concave portion 1H that is concave downward, the convex portion 2T changes greatly in the vertical direction and stimulates the area near the arch of the foot, thereby increasing the massage effect.
