US Patent 6880268 Sock combined with insole

A sock combined with an insole comprises an insole; at least one surface of the insole is formed with elastic hooks; the hooks being deformed due to an external force, but restoring as the force disappears; and a sock having a sock body and an opening; the sock body having a sock sole; whole or part of the lower bottom of the sock sole being formed with curl wires for grasping the hooks so that the sock is tightly secured to the insole to avoid the relative motion between the sock and the insole.
