FIELD OF THE INVENTIONThe present invention relates generally to foot stocking designed to absorb moisture. More particularly, the present invention relates socks configured to present a fashionable appearance while provide fluid absorption from the foot.
BACKGROUND OF THE INVENTIONModern consumer marketing principles teach that profits are most typically maximized when a product can be manufactured and sold in large quantities of the same unit. The sock industry is therefore generally driven to provide socks of pleasing aesthetic appeal, that are made of a single textile or fabric, and that can be mass produced as identical units and sold to the largest available market.

Specialty manufacturing of socks designed to meet special needs of smaller of groups of people tend to result in higher per unit costs. In particular, the fashion industry has been slow to address the needs of diabetics and arthritics in part because the cost of changing over a manufacturing line from the production of one sock design to another can more significantly affect the cost of manufacturing of each sock when unit volumes per production run are lower. Persons with special sensitivities related to footwear, such as diabetics and arthritics, are therefore generally provided with a limited range of commercially available footwear.
Furthermore, conventional dress socks typically are made of types and thicknesses of material that will absorb less moisture than athletic or sports socks. In addition, conventional dress socks often include dyes or coloring agents throughout the sock, including the area of the sock that is placed between a wearer's foot and shoe, wherein heat and moisture build-up increase any potential risk of irritation to the users foot by the dye. Yet, the benefits of providing a sock designed to provide aesthetic appeal while meeting a medical condition of certain types of consumers can be economically significant.
Enabling healthy foot care by diabetics, for example, by providing socks with a higher aesthetic appeal and that can both absorb moisture and be manufactured at unit costs closer to typical sock fabrication costs would reduce the health expenses of diabetic wearers of such socks. There is therefore a long felt need to provide a sock assembly that can be more cost efficiently manufactured to meet the fashion and health needs of certain groups of persons having special medical needs.
The entire disclosures of each and every patent mentioned in this present disclosure, to include U.S. Pat. Nos. 6,606,750, 6,550,289 and 7,007,517 as noted above, are incorporated herein by reference and for all purposes.
