Abstract: A conventional sock, in which a pile yarn knitted into loops together with a polyurethane yarn has cushioning properties, but has a problem in that it cannot be used for a long period of time. According to the present invention, a first component yarn 15a composed of two yarns, namely, a woolly nylon yarn 13a and a cotton yarn 14a, and a second component yarn 15b composed of two yarns, namely, a woolly nylon yarn 13b and a cotton yarn 14b, are alternately knitted into float loops every 10 loops. Accordingly, the cotton yarns that are less stretchable appear on the surface, and thus cushioning properties can be improved. Also, the yarn strength can be increased by the woolly nylon yarns that are highly stretchable, and also the strength can be further increased by using the component yarns each composed of two yarns: a woolly nylon yarn; and a cotton yarn. Accordingly, the obtained sock can be used for a long period of time.
