Abstract
A sock includes a sole having protrusions formed on its inner surface by tuck knitting. The protrusions are spaced from each other in the course direction to define first recesses between the protrusions that are adjacent to each other in the course direction, and spaced from each other in the wale direction to define second recesses between the protrusions adjacent to each other in the wale direction. Each protrusion is formed by knitting six courses in one loop, and includes six rubber threads, 12 reinforcing threads, three front threads and three back threads. The protrusions are arranged in a plurality of rows, each row occupying one course. Between the adjacent rows of protrusions, the second recesses are defined, which each occupy four courses. The protrusions have a height of 3.5 to 4.5 mm from the second recesses.
