Clog sock

Abstract

A foot covering for enclosing a wearer's foot and ankle to facilitate wearing footwear lacking a heel enclosure. The sock includes a first fabric layer having respective forefoot, instep and heel portions covering the wearer's foot in a thin elastic material having a transition seam circumferentially disposed across the instep portion. A second fabric of thick material is disposed in overlying relation proximal of the wearer's upper instep, heel and ankle. The second fabric extends distally from the transition seam across the instep portion of the wearer's foot, to an ankle portion of thick material extending a sufficient length above the heel to encircle the wearer's ankle. The thin first fabric layer enclosing the forefoot minimizes stretching of the toe enclosure of clog shoes or sandals, and the thick second fabric covers the wearer's upper instep, heel and ankle for warmth and/or support while wearing clog shoes or sandals.
