Benefits of technology
The solution results in footwear that is floatable, resistant to water absorption, comfortable, and customizable in color, addressing the issues of water absorption, discomfort, and fungal growth, while maintaining light weight and style.
Problems solved by technology
However, because many of these materials are porous, such footwear readily absorb water and become heavy and cumbersome.
The absorbed moisture or liquid may seep out over time causing discomfort to the wearer, or even causing the wearer to trip or fall.
Moreover, such absorption may stain the footwear or promote the growth of unsightly or odor-causing fungus.
However, seepage is not avoided, nor is the growth of unsightly or odor-causing fungus caused by the trapped moisture.
While many footwear are desirably casual and lightweight, the desire to minimize weight has left many footwear with uncomfortable inner soles that lack a liner that is both comfortable and slip-resistant.

Embodiment Construction
[0023] Referring to FIGS. 1 and 2, an embodiment of a footwear 10 of the present invention is shown. The footwear has a sole 12, including an insole 14 and an outsole 16, and upper member or members (hereinafter used interchangeably) 18 affixed to and extending above the sole 12 for securing the footwear 10 to the wearer's foot (not shown). The upper members 18 may include a strap 20 and a fastening member 22 both adapted and configured to conform to the wearer's foot. In particular, the strap 20 is configured to extend above the foot and the fastening member 22 is configured to extend between the toes of the foot. Referring to FIGS. 5 and 6, the ends 24 of the upper members of this embodiment of the footwear 10 are securely affixed to the outsole 16 by, e.g., adhesives or glue. As understood by one of ordinary skill in the art, the upper members may connected to the sole 12 by a variety of different means, including the formation of a nub at the ends 24 of the upper members which a...

A water-resistant and floatable footwear including an outsole and insole, and an upper member affixed to the sole,wherein the footwear is floatable in water. In particular, the insole of the footwear is constructed of the material “marine buoy;” that is, the insole has an inner structure and an outer coating, the inner structure being constructed of a thermoplastic resin and the outer coating being constructed of a vinyl polymer. The footwear is advantageously water-proof and provides buoyancy in water.
Description
CROSS REFERENCE TO RELATED APPLICATION [0001] The present application is a continuation of U.S. patent application Ser. No. 10 / 264,015, filed Oct. 3, 2002 which is a continuation of U.S. patent application Ser. No. 09 / 690,552, filed Oct. 17, 2000, now U.S. Pat. No. 6,508,016, issued Jan. 21, 2003.FIELD OF THE INVENTION [0002] This invention relates to footwear, in particular, lightweight and comfortable footwear providing buoyancy in water and resistance to water absorption, and a method of manufacture therefor. BACKGROUND OF THE INVENTION [0003] Casual and lightweight shoes, particularly, sandals are known. Many of these shoes and sandals (hereinafter collectively referred to as “footwear”) are flexible due to the materials used to construct the soles. However, because many of these materials are porous, such footwear readily absorb water and become heavy and cumbersome. The absorbed moisture or liquid may seep out over time causing discomfort to the wearer, or even causing the wea...
