Corrective socks featuring elastic bands and reinforcing bands to correct hallux valgus and digitus quintus varus

Abstract

In a corrective sock for correcting hallux valgus and digitus quintus varus of a foot, the sock has a foot portion, and an elastic band formed in the foot portion so as to cover both a metatarsophalangeal joint portion and a Lisfranc joint portion of the foot between which first, second, third, fourth and fifth metatarsals extend. A first reinforcing band is formed on the elastic band to cover a distal caput of the first metatarsal and a distal caput of the fifth metatarsal, and a second reinforcing band is formed on the elastic band to cover a proximal caput of the first metatarsal and a pioximal caput of the fifth metatarsal.

1 . A corrective sock for correcting hallux valgus and diqitus varus minimi of a foot, which sock comprises:
 a foot portion;   an elastic band formed in said foot portion so as to cover both a metatarsophalangeal joint portion and a Lisfranc joint portion of said foot between which first, second, third, fourth and fifth metatarsals extend;   a first reinforcing band formed on said elastic band to cover a distal caput of said first metatarsal and a distal caput of said fifth metatarsal; and   a second reinforcing band formed on said elastic band to cover a proximal caput of said first metatarsal and a proximal caput of said fifth metatarsal.   
   
   
       2 . The corrective sock as set forth in  claim 1 , said first reinforcing band slantly surrounds said foot so as to cover both the distal caput of said first metatarsal and the distal caput of said fifth metatarsal, and wherein said second reinforcing band slantly surround said foot so as to cover both the proximal caput of said first metatarsal and the proximal caput of said fifth metatarsal. 
   
   
       3 . The corrective sock as set forth in  claim 1 , wherein said elastic band includes rubber yarns knitted in said foot portion. 
   
   
       4 . The corrective sock as set forth in  claim 1 , wherein each of said first and second reinforcing band includes non-stretchable strong yarns knitted into said elastic band, 
   
   
       5 . The corrective sock as set forth in  claim 1 , wherein said foot portion has first and second pockets formed in a toe section thereof, so that first and fifth toes of said foot are received in said first and second pockets, respectively. 
   
   
       6 . The corrective sock as set forth in  claim 1 , wherein said foot portion is knitted by a circular knitting machine. 
   
   
       7 . The corrective sock as set forth in  claim 6 , wherein each of said first and second reinforcing bands is formed on said elastic band by knitting non-stretchable strong yarns into said elastic band using either a wrapping stitch method or a plating stitch method. 
   
   
       8 . A corrective sock for correcting hallux valgus and digitus quintus varus of a foot, which sock comprises:
 a foot portion;   an elastic band formed in said foot portion so as to cover both a metatarsophalangeal joint portion and a Lisfranc joint portion of said foot between which first, second, third, fourth and fifth metatarsals extend; and   a reinforcing band formed on said elastic band to cover distal proximal caputs of said first metatarsal and distal and proximal caputs of said fifth metatarsal.   
   
   
       9 . The corrective sock as set forth in  claim 8 , said reinforcing band slantly surrounds said foot so as to cover both the distal caput of said first metatarsal and the distal caput of said fifth metatarsal and both the proximal caput of said first metatarsal and the proximal caput of said fifth metatarsal. 
   
   
       10 . The corrective sock as set forth in  claim 8 , wherein said elastic band includes rubber yarns knitted in said foot portion. 
   
   
       11 . The corrective sock as set forth in  claim 8 , wherein said reinforcing band includes non-stretchable strong yarns knitted into said elastic band. 
   
   
       12 . The corrective sock as set forth in  claim 8 , wherein said foot portion has first and second pockets formed in a toe section thereof, so that first and fifth toes of said foot are received in said first and second pockets, respectively. 
   
   
       13 . The corrective sock as set forth in  claim 8 , wherein said foot portion is knitted by a circular knitting machine. 
   
   
       14 . The corrective sock as set forth in  claim 13 , wherein said reinforcing bands is formed on said elastic band by knitting non-stretchable strong yarns into said elastic band, using either a wrapping stitch method or a plating stitch method.
