Structure improvement of socks

The utility model relates to a sock body with an improved structure which comprises a sock mouth, a sock body and a sock sole. The utility model is characterized in that: the sock mouth, the sock body and the sock sole are all woven by cotton yarn, elastic yarn and blend fabric material. The spacing between the warp threads is quite wide and the spacing between the warp threads on the sock body is quite narrow to form a sock body structure in that the width at the sock mouth is larger than that of the sock body; medium hard and soft concavo convex stripes are arranged on the sock body. As the sock mouth is much wider than the sock body, the sock is made to fit the outer shape of the legs and the sense of extreme binding can be eliminated. In addition, due to the medium hard and soft concavo convex structure, a venting gap is formed between the inner surface of the sock and the skin so as to achieve a comfortable wearing effect.
