DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to footwear such as shoes.

[0002]

2. Description of the Related Art Conventionally, sandals have been known in which a string is passed through a plurality of string through holes provided in the width direction of the bottom (sole) (for example, Japanese Utility Model Application Laid-open No. -57701). However, in this shoe, since the sole is a hard sandal, even if the tightening cord is tightened, the hard sole is pressed against the back of the foot, so that the sole is not deformed, and therefore, a fit cannot be obtained.

There is also known a shoe in which one end of an engagement belt is fixed to a side surface of a sole, and the other end of the engagement belt is engaged with an upper pad made of a hook-and-loop fastener (Japanese Utility Model Publication No. 60-1985). No. 12402). However, in this prior art, the side end of the sole is pulled up toward the instep by the engagement belt, so that the sole is hardly deformed. As a result, it does not adhere to the back of the foot, so that a fit cannot be obtained.

[0004] The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide footwear in which a sole is brought into close contact with the back of a foot to obtain a high fit.

[0005]

According to the present invention, at least three grooves or through-holes extending in the width direction are formed in a sole made of an elastic member having a tread surface on a lower surface. Then, at the instep of the foot, it engages with a plurality of engagement portions for folding and is folded obliquely downward, and is wound along the groove or through hole and the side surface of the foot so that the upper surface of the sole is the back surface of the foot. And a band-shaped or string-shaped tightening member that is pressed against the member.

[0006]

The fastening material extends at least three times in the width direction of the sole.
It is turned to the sole of the foot along the groove or through hole of the book.
Therefore, pulling and tightening both ends of the fastening material,
The fastening member presses the sole made of the elastic member in a state in which the sole is brought into close contact with the back surface of the foot while being deformed into a shape along the back surface of the foot. Therefore, in the footwear of the present invention, since the sole adheres to the entire back surface of the foot, the fit can be sufficiently improved.

And is wound along the side of the foot. Therefore, when the both ends of the fastening member are pulled and fastened, the sole made of the elastic member is brought into close contact with the back surface of the foot while deforming into a shape along the back surface of the foot. Therefore, since the sole is in close contact with the entire back surface of the foot, extremely high fit is obtained.

An instep pad for covering the instep of the foot is provided, and the instep pad is provided with two engaging portions each having a hole for turning back the fastening member.
By forming the rows, the assemblability is improved, and the entire footwear can be brought into close contact with the entire foot, so that the footwear is extremely comfortable.

Further, when the string is engaged with the folded portion of the fastening member, the tightening force of the fastening member is increased by pulling the string, so that a higher fitting feeling can be obtained.

Also, if the outer sole and the midsole are bonded to form a sole and a through hole is formed between the outer sole and the midsole, the formability of the through hole is improved.

By providing an inner body separate from the sole, it is possible to select and replace a desired inner body according to the user's preference and use, and when the member becomes dirty, the inner member can be replaced. Since only the members need to be replaced, the economic burden on the user is reduced. In addition, since the rigidity of the bottom of the footwear is reduced, the sole can be easily fitted to the foot, and the fit is improved.
