Socks with lateral plantar arches

Abstract

The present invention relates to a sock having a lateral plantar arch recess, to a sock having the lateral plantar arch recess in which a certain region of a lateral plantar arch support configured to support a lateral plantar arch is formed at a bottom surface of the sock with the lateral plantar arch recess which is recessed upwardly from a lower surface by a certain thickness, so that the center of gravity of a wearer of the sock is moved rearward and outward while the wearer is standing, thereby reducing the load applied to the hallux, and the center of gravity of the wearer of the sock is moved to between first and second metatarsal bones sequentially through calcaneus, a cuboid bone, and a fifth metatarsal bone while the wearer is walking, thereby delaying pronation as much as possible and causing supination to occur more easily after pronation.

1 . A sock worn on a foot and having a lateral plantar arch recess, wherein a bottom surface of the sock is formed with a lateral plantar arch recess in which a lateral plantar arch support configured to support a lateral plantar arch composed of calcaneus, a cuboid bone, and fourth and fifth metatarsal bones of a wearer is recessed from a lower surface in a predetermined region. 
     
     
         2 . The sock of  claim 1 , wherein the lateral plantar arch recess is formed in a region configured to support the calcaneus, the cuboid bone, and a certain portion of a rear portion of the fourth and fifth metatarsal bones of the lateral plantar arch support. 
     
     
         3 . The sock of  claim 1 , wherein the bottom surface of the sock excluding the lateral plantar arch recess is formed to have the same thickness, and the thickness of the lateral plantar arch recess is formed to be ⅓ to ⅔ of the thickness of the bottom surface of the sock excluding the lateral plantar arch recess. 
     
     
         4 . The sock of  claim 2 , wherein the lateral plantar arch recess is formed so that a boundary line located at an edge of a central side of the lateral plantar arch recess is rounded.
