       BACKGROUND OF INVENTION 
       [0004]    1. Field of the Invention 
         [0005]    The present invention relates generally to foot coverings and more particularly to a new and useful disposable waterproof oversock which is adapted to protect a wearer&#39;s feet and socks while wearing footwear in conditions that may be wet, dirty, soiled or otherwise hazardous. 
         [0006]    2. Background of the Related Art 
         [0007]    The use of socks as a foot covering inside shoes, boots, or other footwear is well known in the prior art. Socks may serve any of several purposes, including maintaining the warmth of feet, preventing injuries to feet due to abrasion with the inner surfaces or edges of footwear, or acting as a barrier between feet and undesirable matter that may penetrate into the footwear. 
         [0008]    Individuals, especially construction workers, utility workers and emergency response personnel, often find themselves operating in difficult environments. In some of these environments, individuals may be required to walk through damp or soiled areas, through puddles of standing water, and even through hazardous conditions in which standing water contains raw sewage or other hazardous materials. Individuals participating in recreational activities, such as hunting, fishing, hiking, camping, boating, and watersports, also confront similar conditions. Therefore, it is desirable to provide a solution that protects feet and socks from liquid and other undesirable elements that may penetrate footwear or reach above the ankle. 
         [0009]    During disaster relief efforts in particular, personnel are required to act quickly entering hazardous situations to save lives and prevent further damage. The delay in donning protective gear can cost precious moments. Therefore, it is desirable to provide a solution that allows protective gear to be applied and removed quickly in emergency situations. 
         [0010]    One common solution is for individuals to first insert their socked feet into any available plastic bags, such as those commonly provided by grocery stores or the bags in which loaves of sliced bread are sold, and then inserting their bag-covered feet into footwear. This solution provides only brief protection as these bags are not designed for this purpose. The durability of such coverings is unreliable, making the bags prone to rips and other failings after minimal abrasion inside footwear. Accordingly, it remains desirable to provide a solution for protecting feet and socks that is durable enough to endure the abrasive conditions expected inside footwear. 
         [0011]    Another disadvantage of this solution is that such coverings are prone to sagging, making it difficult to maintain the covering&#39;s desired position above an individual&#39;s ankle and around their calf. This causes problems when attempting to lower a pant leg over the covering, at which point the covering is likely to be pushed down and expose the ankle and lower leg. A further problem results as the bag sags during use and exposes the ankle and lower leg. In either circumstance, it is possible that the individual is unaware that the bag has sagged or that the ankle and lower leg would now be vulnerable if the individual were required to proceed through some depth of water. It remains desirable to provide a solution that permits the waterproof covering to maintain its position above the ankle while being applied and throughout use in working conditions. 
         [0012]    In an alternative approach, a sock composed of an elastic and waterproof material is provided. The elastic sleeve is pulled on over the individual&#39;s bare or socked foot. One significant concern in using an elasticized sleeve is that the elasticized material will cause difficulty in pulling the sleeve over a bare or socked foot. Another concern is that the elastic material would cause continuous and uncomfortable pressure on the foot. Therefore, it remains desirable to provide a waterproof solution that is not difficult to put on and that does not apply unnecessary pressure upon the foot. A further concern is that the cost of using the elasticized material would be prohibitive for a disposable item. As such, it remains desirable to provide a solution that is inexpensive and disposable. 
         [0013]    An additional solution provides a sock composed of one or more advanced materials that have wicking properties in addition to being waterproof or water-resistant. Such materials prevent moisture from the external environment from reaching the individual&#39;s foot and are capable of drawing any moisture developing inside the sock—as from natural foot perspiration—away from the foot to the exterior of the sock. While this solution offers varying degrees of success in protecting the foot and sock, it embodies several disadvantages. 
         [0014]    One disadvantage of this solution is that the materials employed are prohibitively expensive for use in a disposable solution. A further disadvantage of this solution is that it will be tempting to reuse such an expensive item, causing some to attempt to clean the sock even after it has been exposed to unknown and potentially hazardous contaminants. An individual using such a sock will have been spared contact with undesirable substances during use, only to be unnecessarily exposed to the same substances in attempting to clean it for additional use. Accordingly, it remains desirable to provide a solution that is inexpensive enough to discourage individuals from attempting to clean a soiled sock. 
         [0015]    Another disadvantage of this solution is that it causes the accumulation of moisture within the oversock. The accumulation of moisture inside an oversock is noted particularly in socks and oversocks that fit snugly around the foot. As such, it is the expensive wicking materials used in snugly fitting socks that are contributing to the moisture problem they claim to address. Therefore, it remains desirable to provide a solution that does not encourage the accumulation of moisture within the oversock. 
         [0016]    Yet another disadvantage of a solution that utilizes a snugly fitted oversock is that such oversocks are difficult to slide over the foot and ankle as they are being put on and removed. It is thus desirable to provide a solution that allows the oversock to be put on and removed easily. 
         [0017]    A further disadvantage of this solution is that many of the advanced materials used in this solution are not recyclable. Therefore, it remains desirable to provide a solution that uses readily recyclable materials. 
         [0018]    It is, therefore, an object of this invention to provide a waterproof oversock that will protect a wearer&#39;s foot and sock from becoming wet, soiled or contaminated from contact with external conditions that penetrate the wearer&#39;s footwear. Another object of this invention is to provide a waterproof oversock that protects a wearer&#39;s leg and sock above the ankle when submerged in standing water or other bodies of liquid. A further object of this invention is to provide a waterproof oversock that maintains its position about the ankle during dressing and ordinary usage. Still another object of this invention is to provide a waterproof oversock that will discourage the accumulation of moisture. It is also an object of this invention to provide a waterproof oversock that does not cause discomfort to the wearer&#39;s foot during ordinary use. Another object of this invention is to provide a waterproof sock that is easy to put on and remove. A further object of this invention is to provide a waterproof oversock that is disposable and recyclable. 
       SUMMARY OF INVENTION 
       [0019]    Accordingly, the present invention contemplates a new and improved waterproof oversock, and more particularly, a disposable oversock that is easy to put on and which stays in place above the ankle. The invention eliminates the above-discussed and other drawbacks of the currently employed solutions. 
         [0020]    The invention solves the problem of feet and socks becoming wet and soiled by providing a waterproof oversock that serves as a durable and impermeable barrier to external elements. The problem of maintaining such protection above the ankle is solved by providing a recess within the oversock that encompasses the wearer&#39;s calf area and contributes to securing the oversock in position about the lower leg. The problem of maintaining such protection above the ankle is further solved by providing a means for easily and adjustably securing the oversock in position above and about the ankle. The problem of difficulty putting on a tight fitting elastic sock is solved by providing an oversized oversock that slips easily over a foot even when wearing a thick sock directly on the foot. The problem of moisture build-up inside the oversock is solved by providing an oversized oversock that does not hold the foot tightly. The problem of risking contamination by attempting to clean the oversock is solved by providing an oversock that is disposable and recyclable. 
         [0021]    The invention is particularly suited for use by emergency personnel in disaster relief efforts. The waterproof oversock can be applied quickly without significantly impacting the response times of disaster relief personnel. Similarly, the waterproof oversock may be removed with ease and speed regardless of the presence of additional protective gear or equipment. Furthermore, the generous capacity of the oversock provides the option for it to be worn over the pant leg, extending its protection the bottom of the pant leg in addition to the wearer&#39;s foot, ankle and sock. 
         [0022]    In one embodiment, a waterproof oversock is provided that is loose fitting about the foot and with a means of securing the oversock about the ankle. 
         [0023]    In another embodiment, a waterproof oversock is provided with a seamless surface. 
         [0024]    In a further embodiment, a waterproof oversock is provided with a plurality of points for securing the oversock in place about the ankle.

     DETAILED DESCRIPTION OF INVENTION 
       [0030]    While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings that are herein described in detail. It should be understood, however, that the description herein to specific embodiments is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. It will of course be appreciated that in the development of any such actual embodiment, numerous decisions specific to any particular implementation must be made to achieve the developers&#39; goals, such as compliance with regulatory constraints, which will vary from one implementation to another. In the interest of clarity, not all features of an actual implementation are described in this specification. Moreover, it will be appreciated that such development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure. 
         [0031]    The oversock components discussed herein may be composed of any of a number of sufficiently strong materials and may be formed or constructed by any of a number of processes. Nothing in the descriptions of the embodiments below is intended to be a limitation in the possible materials to be used in constructing any form of this invention. 
         [0032]      FIG. 1  is a side view of a first side of an embodiment of an oversock  100 .  FIG. 2  is a side view of a second side of an embodiment of Oversock  100 . In this first embodiment, oversock  100  is comprised of two layers, layer  102  being visible in  FIG. 1  and layer  103  being visible in  FIG. 2 . Layers  102  and  103  are comprised of polyethylene that is at least 0.003 inches thick. Without doubt, any of a number of other materials meeting the requirements and characteristics of the preferred material could be employed. 
         [0033]    Either the first side or the second side may be described as the left side or right side of Oversock  100  as worn on a foot. Similarly, as worn on a foot, either first or second side may be described as the interior or exterior of the foot and leg upon which Oversock  100  is worn. 
         [0034]    Oversock  100  has the general shape of an oversized traditional sock with a wider opening than is traditionally provided. This embodiment of oversock  100  further diverges from a traditional sock shape by providing an enlarged calf region  104 . As worn, calf region  104  creates a recess in which the wearer&#39;s calf rests. Calf region  104  surrounds the wearer&#39;s calf, providing a more comfortable fit and additional support against sagging. 
         [0035]    Oversock  100  may be provided in a range of foot or shoe sizes with the understanding, however, that Oversock  100  is oversized relative to the size of the intended foot to which it will be applied. Wearer&#39;s foot will rest within region  105  of oversock  100 . 
         [0036]    The profile of Oversock  100  is defined by an upper edge  110  and seam  120  along the remaining perimeter of Oversock  100 . Seam  120  is formed by heat sealing or a similarly effective means of manufacture. As an artifact of manufacture, seam  120  may appear to continue along upper edge  110 . However, layers  102  and  103  are not joined at upper edge  110 . Upper edge  110  defines the opening of Oversock  100  into which a wearer&#39;s foot would be inserted. 
         [0037]    Strips  135  and  136  comprise a hook and loop fastening system, wherein strip  135  comprises a surface of fastening material such as a loop surface and strip  136  comprises a surface of fastening material such as a hook surface. Oversock  100  is secured about a calf by folding the portion of Oversock  100  with strip  136  onto strip  135 . 
         [0038]    Reinforcing strip  160  is securely affixed to Oversock  100  in the vicinity of upper edge  110  approximately 2.5 inches below upper edge  110 . Reinforcing strip  160  may be comprised of either a single strip affixed to both the first side and second side of Oversock  100  or two or more strips attached individually to both the first side and second side of Oversock  100 . Reinforcing strip  170  is securely affixed to Oversock  100  at ankle region  106 . Reinforcing strip  170  may be comprised of either a single strip affixed to both the first side and second side of Oversock  100  or two or more strips attached individually to both the first side and second side of Oversock  100 . 
         [0039]    Strip  136  may be pulled and selectively attached along the width of strip  135 . This individual adjustment allows the wearer to adjustably secure oversock  100  about a range of calf sizes and to customize the positioning to match wearer&#39;s desired fit. The rigidity of strips  135  and  136 , individually and when secured together, prevent flap region  153  of Oversock  100  from sagging about wearer&#39;s calf and ankle. Region  105  remains loose about wearer&#39;s foot before and after being secured. 
         [0040]    Once secured about wearer&#39;s foot, ankle, and calf, Oversock  100  looks, feels, and behaves similar to a standard sock. The wearer may then insert an Oversock-enclosed foot into any other footwear. The low friction properties of layers  102  and  103  allow the Oversock and foot to be slipped into footwear with minimal resistance. 
         [0041]      FIG. 3  is a side view of a first side of a second embodiment of an Oversock  100 .  FIG. 4  is a side view of a second side of a second embodiment of Oversock  100 . 
         [0042]    In this second embodiment, strips  135  and  136  continue to comprise a hook and loop fastening system used to selectively secure Oversock  100  about wearer&#39;s ankle. Reinforcing strip  160  further comprises two ends, and reinforcing strip  170  further comprises two ends. 
         [0043]    Upper tab  131  is securely attached to Oversock  100  in the vicinity of a first end of reinforcing strip  160 . Upper tab  132  is securely attached to Oversock  100  in the vicinity of a second end of reinforcing strip  160 . Lower tab  141  is securely attached to Oversock  100  in the vicinity of a first end of reinforcing strip  170 . Lower tab  142  is securely attached to Oversock  100  in the vicinity of a second end of reinforcing strip  170 . 
         [0044]    Upper tabs  131  and  132  comprise a hook and loop fastening system. Upper tabs  131  and  132  may be pulled and selectively attached to each other. This individual adjustment allows the wearer to further adjustably secure Oversock  100  about a range of calf sizes and to customize how firmly it is secured about the calf. 
         [0045]    Lower tabs  141  and  142  comprise a hook and loop fastening system. Lower tabs  141  and  142  may be pulled and selectively attached to each other. This individual adjustment allows the wearer to further adjustably secure Oversock  100  about a range of ankle sizes and to customize how firmly it is secured about the ankle. 
         [0046]    The particular embodiments disclosed above are illustrative only, as the invention may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. Furthermore, no limitations are intended to the details of construction or design herein shown, other than as described in the claims below. It is therefore evident that the particular embodiments disclosed above may be altered or modified and all such variations are considered within the scope and spirit of the invention. The invention should not be construed as limited to the specific form shown and described, but instead as set forth in the following claims.
