AI Technical Summary
Existing socks fail to fit people with small or large feet comfortably, cause discomfort due to tight elastic threads, and do not address sweat and odor absorption effectively, especially for those with sensitive skin who prefer natural materials.
The cylindrical sock design features a reinforced heel part, reverse-knitted construction, and a combination of elastic threads on the outside and natural materials on the inside to ensure a comfortable fit and improved sweat and odor absorption.
The design provides a comfortable fit for various foot sizes, reduces sweat and odor issues, and eliminates tightness caused by elastic threads, enhancing user comfort and material feel.

Abstract
Description
[Technical Field]
[0001] This relates to cylindrical socks. [Background technology]
[0002] In the past, it was necessary to stock a wide variety of socks for each foot size, and the wide variety of sock shapes meant high costs. Summary of the Invention [Problem to be solved by the invention]
[0003] There were issues with socks that didn't fit people with particularly small or large feet, with tight elastic threads at the opening, and people with sensitive skin who wanted to wear natural materials but whose 100% natural fiber socks kept slipping off. This product aims to solve the tightness of elastic so that socks fit the feet of people with large, small, or any other foot type, without sweating or getting sweaty, and improves sweat and odor absorption by reverse-knitting the front and back yarns. [Means for solving the problem]
[0004] The cylindrical sock is characterized in that it comprises an upper opening 2 which is an entrance for putting on the sock, a toe part 4 which covers the toes at the tip of the sock, and a main body 3 other than these, the main body 3 comprising a heel part 32 for covering the heel and a leg part 31 other than the heel part 32, and the heel part 32 is reinforced more than the leg part 31.
[0005] This cylindrical sock is characterized in that the upper opening 2, which is the entrance to put on the sock, the toe part 4 covering the toes at the tip of the sock, and the main body 3 other than these are all reverse knitted.
[0006] The cylindrical socks are characterized in that the opening 2 uses elastic threads (polyurethane / nylon) on the outside where they do not come into contact with the skin, the leg part 31 of the main body 3 uses elastic threads (polyurethane / nylon) on the outside and natural materials on the inside, the heel part 32 of the main body 3 uses the same number of elastic threads (polyurethane / nylon) as the leg part and the inside uses more natural materials for reinforcement than the leg part, and the toe 4 has the same structure as the heel part and uses the same number of elastic threads (polyurethane / nylon) as the leg part and the inside uses more natural materials for reinforcement than the leg part. [Effects of the Invention]
[0007] It is possible to provide socks that fit the size of each individual's feet. The reverse knitting method improves absorption of sweat and odor, and the absence of elastic at the opening eliminates the uncomfortable tightness that can be caused by elastic. [Brief explanation of the drawings]
[0008] [Figure 1] Construction of the cylindrical sock of the present invention DETAILED DESCRIPTION OF THE INVENTION
[0009] The cylindrical socks of the present invention are cylindrical socks with no heel, made cylindrical and designed to fit the foot, with the material on the front and back of the socks reverse knitted. The front side has no heel and is cylindrical, allowing for a structure that fits each individual foot. The socks are constructed without rubber, with natural fibers used on the inside (the side that touches the skin) and elastic yarn used on the outside (the side that does not touch the skin).
[0010] As shown in Figure 1, the cylindrical sock 1 of the present invention is composed of an upper opening 2 where the sock is put on, a toe part 4 at the tip of the sock that covers the toes, and a main body 3 other than these. The main body 3 is composed of a heel part 32 that covers the heel, and a leg part 31 other than the heel part 32. The heel part 32 is more reinforced than the leg part 31.
[0011] The opening 2 does not use rubber, but uses elastic thread (polyurethane / nylon) on the outside where it does not come into contact with the skin, so the shoe does not slip off even without using rubber, and the inside of the shoe is made of natural materials that feel good against the skin and absorb sweat and its odor.
[0012] The leg part 31 of the main body 3 uses elastic thread (polyurethane / nylon) on the outside and natural material on the inside.
[0013] The outside of the heel part 32 of the main body 3 uses the same number of elastic threads (polyurethane / nylon) as the leg part, and the inside uses more natural material than the leg part for reinforcement.
[0014] The toe 4 has the same structure as the heel, and uses the same number of elastic threads (polyurethane / nylon) as the leg, and the inside uses more natural material than the leg for reinforcement. [Explanation of symbols]
