[Action]

 When the footwear of the present invention is worn on the foot, the main body covers the sole of the foot as a whole, and the upper surface of the main body contacts the sole of the foot. The instep cover connected to the side end of the main body is folded upward to form the instep cover. The instep cover covers the instep of the foot when worn, and the footwear of the present invention is attached to the foot by inserting the foot between the instep part and the main body.

By constructing the footwear with corrugated paper, the rigidity of the footwear as a whole is increased, the footwear is easy to wear, and the shape is not lost, so that the footwear lasts a long time. In addition, since the corrugated paper has an uneven surface on the top, it gives a comfortable stimulus to the soles of the feet, resulting in good comfort. Moreover, the unevenness of the corrugated paper creates a gap between the floor and the foot, and the heat insulation does not directly transfer the floor temperature to the sole of the foot.

The main body folded so that the lower surface faces the inside can be maintained and fixed in the stored state by bending the upper cover piece to the opposite side and forming the upper cover inside out. By folding the bottom side inward, the dirty side is not exposed to the outside, so even if it is stored in a bag, other things will not get dirty. Further, by providing the main body with a deodorizing means, it is possible to suppress the diffusion of foot odor.
