Description

  The present invention relates to footwear having a sole on which a foot is placed and a covering portion such as an upper covering an instep, and more particularly to a sandal or a highly breathable shoe having a sole structure suitable for use on a sandy beach or the like. is there.

  When flip-flops are used on sandy beaches and the like, sand containing moisture adheres to the bottom of the sole as a lump, or dry sand soars and accumulates on the top of the sole. Also, if you enter the waterside or poolside shallows while wearing flip flops, you may unexpectedly be affected by water resistance, making it difficult to walk or slipping on your feet. Further, when the beach sandals are worn with the feet wet with water, there is a problem that the soles of the feet are in close contact with the upper surface of the sole of the beach sandals, which makes it easy to get stuffy.

  Patent Document 1 discloses a clog having a shiatsu effect in which an infinite number of air holes penetrating from the front surface to the back surface of the clog stand are provided. However, these sandals and clogs are mainly used for the shiatsu effect, and are not examples of application to beach sandals. If sandals with small irregularities or holes are used on a sandy beach, the above-mentioned problem of sand adhesion still occurs, and even if a hole with a small diameter is provided, water resistance problems and stuffiness The problem is not improved.

  Further, when a large number of holes having a small diameter as shown in the following Patent Document 1 are applied to the sandal, the hole 105 is linearly formed on the sole 103 of the sandal 101 from the top surface to the bottom surface of the sole 103 as shown in FIG. It will penetrate. Therefore, if the projection 107 shown in the figure is accidentally stepped on and the projection 107 fits into the hole 105, the sole 103 has sufficient rigidity to prevent the projection 107 from entering. Even if it is, the protrusion 107 penetrates the sole 103 and reaches the upper surface of the sole 103.

  The above-mentioned stuffiness problem is particularly noticeable in shoes where the upper covers the entire upper. For example, doctors and nurses often wear shoes even in hospitals. However, since work continues for a long time, the inside of the shoes inevitably gets muddy, resulting in considerable discomfort.

  The present invention has been made in view of such background technology and the problems of the background technology, and has little adhesion of sand and the like, and has low water resistance when used in water. It is an object of the present invention to provide footwear such as sandals that has a high design effect, and is less likely to cause stuffiness on the back of the skin and also has an acupressure effect.

According to the first aspect of the present invention, in the footwear having a covering portion covering at least a part of the instep of the foot on the sole on which the foot is placed, the sole has an outer frame forming an outer shape, and an appropriate interval is provided in the outer frame. Provided with an inner collar formed by appropriately combining rod-shaped or plate-shaped collar elements, and the opening section partitioned by the outer frame and the inner collar is such that the bottom opening and the top opening are displaced in the horizontal direction. It is the footwear characterized by being formed diagonally.

The invention described in claim 2 is the footwear described in claim 1, wherein the footwear is a sandal.

The invention described in claim 3 is the footwear described in claim 1 or 2 , wherein the footwear is an indoor shoe.

A fourth aspect of the present invention is the footwear according to the second aspect of the present invention, wherein a ventilation hole is formed in the cover portion.

Even if the sandals which are the footwear of the present invention are used as sandals on the beach, the adhesion of the sand to the sole is greatly increased by the large gap of the opening area formed between the heel elements and the easy separation shape of the heel elements. Less. Also, sand does not accumulate on the upper surface of the sole, and even if the sandals are put into the water, the resistance of the water is small, so that it is easy to walk and there is little risk of falling. Also, even if you wear sandals with your feet wet, the soles of your feet won't get stuffy.
In addition, when a material such as a bead is included in the material constituting the heel element, it is possible to impart a design effect to the sandal. Further, when the sole is provided with an inclined hole or an obliquely formed opening, even if the projection is stepped on, the projection does not reach the upper surface of the sole. In addition, due to the presence of an opening having a large diameter, raw material costs can be reduced and sandals can be reduced in weight.
The shoe which is the footwear of the present invention can also prevent the sole of the foot from becoming stuffy, and if the sole is provided with an inclined hole or an opening formed obliquely, the projection is not on the sole surface even if the projection is stepped on. Never reach. In addition, due to the presence of an opening having a large diameter, raw material costs can be reduced and weight can be reduced.
