In general, the foot is a part of the body that maintains the balance of the human body and absorbs shock by supporting the body weight.

As a means for protecting and warming the feet, socks, stockings, or overshoes (hereinafter, collectively referred to as "foot clothing") are used.

Among foot garments, overshoes are made of elastic fibers such as nylon or cotton, and have excellent elasticity and ventilation, so women can easily wear them indoors in their daily life.

These overshoes are made by sewing a number of patterns covering the soles, insteps, and heels of the soles, insteps and heels woven with elastic fibers such as nylon, etc., with elastic threads, and a rubber band is installed around the opening so that they do not come off with sewing threads.

That is, in the conventional overshoes, a plurality of pattern pieces such as a sole cover pattern, a toe cover pattern, and a heel cover pattern are sewn and connected, or the edge of the sole cover pattern is placed against each other in a pattern in which the toe and heel cover patterns are integrated. The overlapping pattern parts are connected by stitching, and the opening formed by stitching is made of rubber-like material.

It is attached by sewing an elastic rubber band with a sewing thread.

These conventional overshoes have a problem in that, by sewing and connecting each pattern, a thick or convex seam is formed in the region where each pattern is connected, and when worn on the foot, the seam puts pressure on the foot, thereby reducing the fit.

As a no-sewing technology, there is a "manufacturing method for men's burlap (Korean Patent Registration No. 1586363)".

This "manufacturing method for over-beoches" is configured to heat-seal hot melt to improve the fit of over-beoches.

However, the conventional men's over-beams are thermally fused by attaching a tape-type hot melt, so the manufacturing process is complicated, and the manufacturing cost is high due to the thermal fusion.

In addition, the conventional men's burlap socks are provided with a cushion pad to improve the cushioning, but there is a problem that the floor is slippery.

Therefore, compared to the tape-type hot melt, manufacturing is simpler, and there is a need for a padding that can prevent slipping along with a cushioning feeling.
