Sock Having a Toes Lock Component

Abstract

A sock for covering at least a foot of a human wearer includes: a knitted toes-covering fabric-region, configured to cover toes of the foot; a knitted sole-covering fabric-region, configured to cover a sole of the foot; and a knitted toes-region stabilizing component, located between the knitted toes-covering fabric-region and the knitted sole-covering fabric-region. The knitted toes-region stabilizing component is configured to stabilize, and to prevent shifting or slippage of, the knitted toes-covering fabric-region in response to body movements. The knitted toes-region stabilizing component is a knitted band that is formed of a first yarn which is a High-Friction Low-Slippage yarn; the knitted toes-covering fabric-region and the knitted sole-covering fabric-region are knitted of a second, different, yarn. The first yarn has a first friction coefficient relative to human body; the second yarn has a second friction coefficient relative to human body; the first friction coefficient is greater than the second friction coefficient by at least 25 percent.
