Abstract
A water sock forming a tubular body having a pair of opposing, open ends that allow the water sock to be put on and removed as easily as any sock. The simple design of this water sock makes it compatible with any type of outer footwear. In one exemplary embodiment, a stretchable toe strap extends between opposing sides of the water sock adjacent to one of the open ends. This toe strap is received between two of the wearer's toes during use and prevents the water sock from sliding rearward toward the wearer's heel.

DETAILED DESCRIPTION
(9) Referring to
(10) Toe strap 26 extends between and is secured to opposing sides of circumferential band 20 and, as shown in
(11) Referring to
(12) Water sock 10 may be formed by any or any combination of knitting, stitching, weaving, or sewing. Preferably, water sock 10 is woven or knitted from a blend of materials, either natural or synthetic. For example, water sock 10 may be formed from a combination of cotton, a polychloroprene, such as Neoprene polychloroprene, nylon or polyester, i.e., polyethylene terephthalate or PET, for durability and a spandex, such as Lycra brand fiber, for expandability. Neoprene is a trademark of Dupont Performance Elastomers of Wilmington, Del. In one exemplary embodiment, water sock 10 is formed from as little as 65 percent, 70 percent, or 80 percent and as much as 85 percent or 90 percent of at least one of cotton, polychloroprene, nylon, or polyester. In one exemplary embodiment, water sock 10 is formed from as little as 10 percent, 15 percent, or 20 percent and as much as 25 percent, 30 percent, or 35 percent spandex fibers.
(13) By forming water sock 10 using at least 10 percent spandex fiber and no more than 35 percent spandex fiber, the desired amount of stretch will be provided to water sock 10. Specifically, water sock 10 will have an amount of stretch that is substantially within a range of 25 percent to 40 percent. Thus, water sock 10 will be able to expand such that the periphery of the material forming water sock 10 has a surface area that is 25 percent to 40 percent greater than when the material forming water sock 10 is in an unexpanded or natural state. By forming water sock 10 of a material that allow for an amount of stretch that is substantially within a range of 25 percent to 40 percent, water sock 10 will cling to the wearer's foot and will be retained securely on the wearer's foot. In certain embodiments, this clinging effect will actually be enhanced when the material is wet ensuring that water sock 10 is maintained in its desired position even during vigorous aquatic activities. In one exemplary embodiment, water sock 10 is formed from a blend of 85 percent nylon and 15 percent Lycra brand fiber. This combination of materials is also sufficient to provide an amount of stretch that is substantially within the range of 25 percent to 40 percent.
(14) Advantageously, the use of a nylon/spandex blend, for example, provides a two-way stretch capability that allows the material forming water sock 10 to move freely and to spring back into its original shape immediately. Stated another way, the use of a nylon/spandex blend makes water sock 10 resiliently deformable, such that water sock 10 will expand to accommodate a wearer's foot and will contract against the surface of the wearer's skin to position the water sock securely on the wearer's foot. Further, any seam construction, as may be necessary for the formation of water sock 10, is performed using a polyester, nylon, or thread of a stretchable nature, for example, that creates a durable seam using a flatlock stitch, for example. In addition to providing for the expansion of water sock 10, the use of spandex also provides water sock 10 with a resistance to sunlight, body oils, and other chemicals, such as chlorine. In addition to the combination of materials set forth above, the use of nylon may be supplemented by using silver coated nylon fiber or by using charcoal fibers, bamboo fibers, and/or other natural fibers that provide water sock 10 with an antimicrobial, UV protecting barrier.
(15) Similarly, circumferential bands 20, 22 and toe strap 26 of water sock 10 may be formed separately from the general body of water sock 10, which is described in detail above. In exemplary embodiments, circumferential bands 20, 22 and toe strap 26 are formed from reinforced fabric or elastic materials, such as any of the materials set forth above with respect to the construction of water sock 10 either alone or in combination with one or more of each other. In exemplary embodiments, toe strap 26, which forms a bridge between opposing sides of open end 16 and may be connected to circumferential band 20, may be sewn or stitched in a conventional manner. In one exemplary embodiment, toe strap 26 is formed during the formation of the main body of water sock 10 and is formed as a unitary component of water sock 10, which eliminates the need to use seamed construction to form toe strap 26.
(16) Referring now in detail to
(17) Regions 32, 34, 36 of water sock 10 are formed as slip resistant regions on the bottom of water sock 10. In one exemplary embodiment, each of regions 32, 34, 36 have an articulated structure and a thickness that does not exceed 3/16 of an inch. This allows regions 32, 34, 36 to have high flexibility and high stretchability. In one exemplary embodiment, regions 32, 34, 36 are formed from an elastomeric polymer. For example, in one exemplary embodiment, the polymer is heat and/or melted and positioned on regions 32, 34, 36, such that the polymer interdigitates with the material forming water sock 10. Then, once the polymer cools, the polymer is securely bonded to the material forming the bottom of water sock 10 adjacent to regions 32, 34, 36. In another exemplary embodiment, the polymer may be formed as a sheet that is stamped or otherwise processed to have a desired shape, such as the shape of each of regions 32, 34, 36. Then, the polymer may be secured to the material forming the bottom of water sock 10 in any known manner, such as by ultrasonic welding.
(18) In other exemplary embodiments, the polymer material used to form regions 32, 34, 36 has an enhanced slip resistance that is achieved by adding a grit material to the polymer. In exemplary embodiments, the grit material is one of or a combination of sand, silicon carbide, and aluminum oxide. By adding a grit material to the polymer, the surface area of regions 32, 34, 36 is increased and the friction generated between a contacting surface, such as the ground, and regions 32, 34, 36 is correspondingly increased. As a result, the slip resistance of regions 32, 34, 36 and water sock 10 is increased.
(19) In one exemplary embodiment, regions 32, 34, 36 have a non-skid, textured surface that is formed by creating deviations in the thickness of the material, which results in the surface of the material forming an undulated surface. In one exemplary embodiment, regions 32, 34, 36 are formed from Toughtek fabric, which is a fifty-percent cotton, fifty-percent polyester, flexible, drapable, abrasion-resistant fabric coated with polyvinyl chloride. Toughtek is a registered trademark of Harrison Technologies, Inc., of Broadalbin, New York. In another exemplary embodiment, regions 32, 34, 36 are formed from a 100% polyester knit, stretchable fabric, coated with a textured coating of Neoprene polychloroprene. In one exemplary embodiment, regions 32, 34, 36 have a thickness of at least substantially 1/32 inch and no more than substantially 3/16 inch.
(20) Additionally, while depicted as being form from a substantially continuous material, regions 32, 34, 36 may be formed from a material that intermittently covers the area defined by regions 32, 34, 36, such as by a series of projections. For example, in one exemplary embodiment, a series of separate, individual dot-shaped projections are formed in regions 32, 34, 36 from a polymer material. These projections may be formed by placing a discrete amount of melted and/or liquid polymer at specific locations within regions 32, 34, 36. The polymer will then cool and/or set, bonding the polymer to the material of water sock 10. In another exemplary embodiment, the material forming regions 32, 34, 36 may be sprayed on, such as by forming an aerosol, or may be secured using an adhesive, such as an epoxy. Regions 32, 34, 36 may also be secured to water sock 10 using any other known method, such as sewing or stitching.
(21) While described and depicted herein as having three distinct regions of enhanced slip resistance, i.e., regions 32, 34, 36, any of regions 32, 34, 36 may be used singularly or in different combinations with one another. For example, in one exemplary embodiment, regions 32, 36 are present on water sock 10, while region 34 is absent. In addition, the position and orientation of sole regions 32, 34, 36 may be modified to cover different areas of the bottom of water sock 10.
(22) In contrast with known water shoes, the use of regions 32, 34, 36 formed according to any of the methods and from any of the materials set forth herein results in the bottom of water sock 10 being lightweight and flexible. Additionally, unlike known water shoes, regions 32, 34, 36 do not inhibit the natural movement of a wearer's foot during aquatic activities.
(23) Water sock 10 may be positioned on a wearer's foot in a substantially identical manner as a normal sock. Specifically, an individual wearer of water sock 10 advances their toes 28 through open end 18 of heel engaging portion 14 and passes their toes 28 out of open end 16 of foot engaging portion 12. As shown in
(24) Once in the position shown in
(25) Advantageously, in exemplary embodiments, the water sock 10 of the present invention clings to the foot of the wearer when wet, has a flexible, lightweight sole portion including an open toe region that cooperatively articulates, flexes, stretches or otherwise moves to provide a wearer with the sensation of feeling the surface below the toes, and provides the wearer's foot a natural, full range of motion in the variable conditions therein during any aquatic activity, such as swimming as shown in
(26) While this invention has been described as having a preferred design, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
