An insole formed in a sheet shape that matches the shape of the sole of the foot of the foot, and is inserted between the covering in the covering and the sole of the foot of the user A first rubber material that covers the entire surface of the back side of the portion on which the insole body is placed on the outer surface of the covering body, and from the front end of the covering body to the vicinity of the mouth of the covering body. And a second rubber material that stretches and a third rubber material that stretches from the rear end of the covering toward the vicinity of the mouth of the covering. provide.

　本発明の履物の被覆体は、伸縮性を有する生地とその外面の一部を覆うゴム素材とからなる。被覆体は、その先端を履き口に入れるようにして丸めることにより拳程度の大きさになる。また、履物の第１のゴム素材は、被覆体の外面における中敷体を載せる部分の裏側の部分の全面を覆っている。このため、使用者は、履物を足に装着して走る際に地面をしっかりと蹴って前進することができる。また、被覆体の外面には、被覆体の前端及び後端から被覆体の履き口の近傍に向かって延伸する第２及び第３のゴム素材が設けられている。このため、履物を足に装着して走る際に被覆体が左右に撚れて足が抜ける恐れがない。よって、本発明によると、スポーツシューズを持参し難い場所（例えば、出張先や旅行先など）に履物を持参し、スポーツシューズの装着時と同程度に快適な運動を行うことができる。 The footwear covering of the present invention comprises a stretchable fabric and a rubber material covering a part of its outer surface. The covering body becomes a size of a fist by rolling the covering body so that its tip is put into the wearing mouth. Further, the first rubber material of the footwear covers the entire surface on the back side of the portion on the outer surface of the covering where the insole is placed. For this reason, the user can move forward while firmly kicking the ground when running with the footwear attached to the foot. Moreover, the 2nd and 3rd rubber | gum raw material extended | stretched toward the vicinity of the mouth of a covering from the front end and back end of a covering is provided in the outer surface of the covering. For this reason, there is no fear that the covering body is twisted right and left when the footwear is worn on the foot and the foot is pulled out. Therefore, according to the present invention, it is possible to bring footwear to a place where it is difficult to bring sports shoes (for example, a business trip destination, a travel destination, etc.) and to perform exercises as comfortable as when wearing sports shoes.
