Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61/407,446 filed on Oct. 28, 2010, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The disclosure relates in general to the field of hosiery and more particularly to socks that have an insert to enhance the fit of shoes on a person's feet.

BACKGROUND

Finding a shoe that fits properly or comfortably can be a challenge. People are often forced to wear shoes that fit poorly because their feet do not fit within a conventional shoe size. Even when selecting among the best fitting size available for a given shoe style, the shoe may not necessarily fit well or comfortably. For example, a person's feet size may fall in-between shoe sizes. When shoes do not fit properly, the shoes have a tendency to slip off a person's feet. For example, the back portion of a shoe sometimes slips off a person's heel during walking, running, or other types of activity. In addition, the person's feet can move around excessively inside the shoe, resulting in abrasion and sores. There are no known devices that address these issues effectively to improve shoe comfort and fit.

SUMMARY OF THE DISCLOSURE

Embodiments of the improved sock address a dilemma many consumers find themselves in whenever their feet size is in-between shoe sizes. Shoe fit and comfort is left desired when a consumer is forced to choose between a shoe that is too tight and a shoe that is oversized. The wearer of an embodiment of the improved sock can achieve this desirable shoe fit and comfort even if the shoe size does not match the wearer's foot size.
In accordance with at least one of the embodiments disclosed herein, the improved sock is for use with an oversized shoe. Similar to a conventional shoe, the oversized shoe has a counter and a topline above the counter. The improved sock compensates for gaps in an oversized shoe, such as the one between the heel of a wearer and the counter, by assisting to push the foot forward in the shoe; in some embodiments, the improved sock can push the foot completely forward in the shoe. The improved sock comprises a toe portion, a foot portion, a heel pocket area, and an upper cuff portion with an opening to receive a foot of a wearer, wherein the foot portion extends from the toe portion to the heel pocket area, and the upper cuff portion is positioned on an end of the sock opposite the toe portion. A heel padding is disposed within the heel pocket area, and the combined thickness of the sock and heel padding can be roughly equal to the gap between the wearer's heel and the shoe counter; and in some embodiments, the thickness can be at least equal to the gap between the wearer's heel and the shoe counter. The heel padding is configured on the sock to be positioned below the shoe topline and push the wearer's foot forward inside the shoe. The heel pocket area is defined as an area of the sock that extends from the base of the wearer's heel bone to approximately the calcaneal insertion of the Achilles tendon when the sock is worn by the wearer.
In some embodiments, the improved sock further comprises a pouch disposed in the heel pocket area for receiving the heel padding. In some embodiments, the heel padding is removably coupled to the sock. In some embodiments, the heel padding wraps partially around the heel pocket area such that the heel padding rests below the wearer's Achilles tendon when the sock is worn by the wearer.
In another embodiment, the improved sock comprises a toe portion, a foot portion, a heel pocket area, and an upper cuff portion with an opening to receive a foot of a wearer, wherein the foot portion extends from the toe portion to the heel pocket area, and the upper cuff portion is positioned on an end of the sock opposite the toe portion. A heel padding is disposed within the heel pocket area. The heel padding is configured on the sock to be positioned below the shoe topline and push the wearer's foot forward inside the shoe. The heel pocket area is defined as an area of the sock that extends from the base of the wearer's heel bone to approximately the calcaneal insertion of the Achilles tendon when the sock is worn by the wearer.
In some embodiments, the heel padding is disposed in the top half of the heel pocket area. In some embodiments, the heel padding has a short-axis and long-axis, and is symmetrical along both axes. In some embodiments, the heel padding can conform to a curvature of an interior surface of the counter of the shoe. In some embodiments, the heel padding can extend beyond the heel pocket area so that a superior edge of the heel padding is disposed between the calcaneal insertion of the Achilles tendon and the shoe topline when the sock is worn by the wearer in the shoe. In some embodiments, the heel padding is made of a polyurethane foam. In some embodiments, the heel padding is integrated with the sock. In other embodiments, the heel padding is removably coupled to the sock.
In some embodiments, the improved sock further comprises a pouch disposed in the heel pocket area for receiving the heel padding and securing the heel padding to the sock. In some embodiments, the heel padding can be adjusted within the heel pocket area and positioned to achieve a target orientation for maximizing individual fit and comfort of the wearer.
In some embodiments, the improved sock further comprises marked reinforced sections in the heel pocket area. The marked reinforced sections provide landmarks for the wearer to achieve target orientation of the heel padding on the sock.
Methods for making the improved sock are disclosed herein. In some embodiments, the method is for making a sock for use with an oversized shoe. The shoe has a counter and a topline above the counter. The topline defines an opening for receiving a wearer's foot. The method, in some embodiments, comprises defining a heel pocket area on the sock for receiving the heel of a wearer such that the heel pocket area extends roughly from the base of the wearer's heel bone to approximately the calcaneal insertion of the Achilles tendon when the sock is worn by the wearer. The method further comprises, providing a heel padding that is symmetrical from left and right, and front and back, the heel padding comprising a symmetrical line separating the left and right. The method further comprises defining a target orientation within the heel pocket area for positioning the heel padding to maximize shoe fit and comfort of the wearer. The method further comprises positioning the heel padding within the target orientation and aligning the symmetrical line of the heel padding coincident with the sagittal plane of the sock. The method further comprises coupling the heel padding to the sock.
In some embodiments, the heel padding is integrally made with the sock. For instance, the method could further comprise sewing the heel padding to the sock. In other embodiments, the method comprises adhering the heel padding to the sock.
In some embodiments, the method further comprises creating a pouch on the sock within the heel pocket area. In some embodiments, the method includes placing the heel padding in the pouch and positioning the heel padding on a top half of the heel pocket area such that the symmetrical line of the heel padding is coincident with the sagittal plane of the sock.
In some embodiments, the method comprises selecting a material for the heel padding from a selection consisting of polyurethane, cotton, cotton-polyester blend, nylon, vinyl, rubber, leather, satin, or silicone.
Although certain embodiments, features, and examples have been described herein, it will be understood by those skilled in the art that many aspects of the methods and devices illustrated and described in the present disclosure may be differently combined and/or modified to form still further embodiments. For example, any one component of the sock assembly illustrated and described above can be used alone or with other components without departing from the spirit of the present invention. Additionally, it will be recognized that the methods described herein may be practiced in different sequences, and/or with additional devices as desired.

DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

Socks with heel padding, described herein, can improve the fit of shoes on a person's feet. The wearer of an embodiment of these improved socks can have an improved shoe fit without having to resort to uncomfortable options.
Many consumers find themselves in-between shoe sizes, such as when one particular size of shoe is too tight yet the next available shoe size is slightly too large. Retrofitting a slightly oversized shoe by stuffing the toe portion with various materials or by attempting to wear double or thicker socks are not ideal solutions and may in fact lower the overall level of comfort for the consumer. From a retail perspective, consumers would worry less about purchasing a shoe that does not fit well if they had socks with heel padding. For example, caregivers of children and adolescents may take a keen interest in this sock concept as this population experiences a high turnover of shoes from growth spurts. Also, individuals with a prior inventory of slightly oversized shoes may be able to take advantage of the improved fit afforded by using embodiments of socks with heel padding.
A person can wear an embodiment of the improved sock in a manner similar to that used when wearing any other kind of sock. A person can pull on an individual sock onto the desired foot and make any adjustments necessary to maximize comfort prior to inserting the outfitted foot into a respective shoe. When the person wears the device in a shoe, his/her foot can be positioned slightly forward in the shoe. Additionally, the medial and lateral sides of the heel can be supported against the sides of the shoe. The positioning of the foot anteriorly in the shoe can be attributed to the cushioning provided by the heel padding and the minimizing of any potential gap between the wearer's heel and the shoe counter.
A sock having desirable features and advantages will now be described with reference to the figures. Although the following description is provided in the context of an exemplifying sock with heel padding, the features of the present sock can provide advantages in other applications as well, for example stockings, gloves, helmets, etc.
The illustration in FIG. 1 shows a close-up side view of the internal anatomy of a rear portion of a foot of a person. The heel bone 2, or calcaneus, is the largest bone of the foot and forms the foundation of the rear portion of the foot. The Achilles tendon 6 is the largest and strongest tendon of the foot and originates from the calf muscles and attaches to the heel bone 2 at the calcaneal insertion 4 located on the posterior surface of the heel bone 2. Reviewing the anatomical structures depicted in FIG. 1 can be useful in understanding the embodiments of the improved sock with heel padding discussed in detail below.
An embodiment of the improved sock is shown in FIGS. 1A-1C, with padding, support, or cushioning at the heel portion of the sock. As illustrated in FIG. 1A, the sock can have a foot portion extending from the toe area 10 to the heel pocket area 12 and a leg portion extending from the heel pocket area 12 to an upper cuff portion. A heel padding 14 can be located in the heel pocket area 12, preferably in the top half of the heel pocket area 12. Excessive exposure of the heel padding 14 towards the bottom half of the heel pocket area 12 is preferably avoided to prevent the likelihood of the heel padding 14 encroaching onto the plantar (bottom) surface of the foot upon wearing.
The final manufactured product preferably will have the heel padding 14 affixed at a desired location as described above. However, it can be possible that the wearer may wear the sock with the heel padding 14 in an improper position on the foot. To help avoid this situation, the heel padding 14 can be manually adjusted by the wearer into a target position to cover the majority of the posterior aspect and portions of the medial and lateral aspects of the heel bone 2 of the foot, as illustrated in FIGS. 1B and 1C. This target position can allow for the heel padding 14 to best cradle the curvature provided by the interior surface of the rear shoe counter area of a conventional shoe. Also, reinforced sections of the heel pocket area 12 and toe area 10 marked on many commercially available socks can assist the wearer in achieving this target orientation since visualization of these landmarks can minimize potential misalignments, such as the heel padding 14 sitting too high, too low, or skewed medially or laterally on the foot upon wearing. It should be noted that the presence of marked reinforced sections for the heel pocket area 12 and toe area 10 can be optional elements for the final manufactured version of this sock assembly. Borders for these optional areas are shown with dashed lines in the figures.
In some embodiments of the sock assembly, the heel padding 14 can be permanently attached to the sock by any method now known or discovered in the future, such as sewing, hook and loop fasteners, snaps, adhesives, Velcro, etc. In embodiments where the heel padding 14 is sewn to the sock, a plurality of different types of thread and a plurality of different types of stitching can be used. The heel padding 14 can be coupled to the exterior of the sock or coupled to the interior of the sock. In some embodiments, the heel padding 14 can be an integrated component of the sock, such as for example where the heel padding 14 is embedded in the sock.
The heel padding 14 can have a generally elliptical or ovular shape with opposing ends tapering to generally a point, as shown in FIG. 1D, with a short-axis 20 that is approximately half the length of the long-axis 22. In some embodiments, the short-axis 20 can be at least approximately 1 inch and/or less than or equal to approximately 3 inches in length. The long-axis 22 can be at least approximately 2 inches and/or less than or equal to approximately 5 inches in length. In other embodiments, the length of the short-axis 20 and/or the length of the long-axis 22 can be any other dimension.
It should be noted that the heel padding 14, as shown in FIG. 1D, can possess lines of symmetry along the short-axis 20 and long-axis 22 that allow the heel padding 14 to retain the same landscape footprint regardless of rotation along either axes, which can advantageously help with simplicity and speed during the manufacturing process. Also, the line of symmetry along the short-axis 20 can be coincident to the sagittal plane of the foot upon wearing, as shown in FIG. 1C, allowing the final manufactured sock assembly the flexibility to be worn on either foot, similar to a conventional sock.
In other embodiments, alternative shapes of the heel padding 14, with or without lines of symmetry, are also contemplated. The overall dimensions of the heel padding 14 can vary taking into account the size of the final manufactured product (e.g., a smaller padding member reserved for socks worn by children and a larger padding member reserved for socks worn by adults). The thickness of the heel padding 14 can be at least approximately 0.125 inch (⅛0 inch) and/or less than or equal to approximately 0.375 inch (⅜ inch), although other thicknesses are contemplated as well.
The material of the heel padding 14 can be made of a flexible and durable material such as polyurethane foam. However, use of other materials such as cotton, cotton-polyester blends, nylon, vinyl, rubber, leather, satin, suede, gel, silicone, fluid-filled material, Lycra, Spandex, or any other natural or synthetic textile material is also contemplated.
Although the sock assembly illustrated in FIGS. 1A-1C is an athletic-type sock, the heel padding 14 can be incorporated into any sock type (e.g., no-show, ankle, quarter, crew, over-the-calf, athletic, casual, dress, men's, women's, etc.) or any sock size (e.g., infant, child, adolescent, adult, etc.).
At least some of the benefits of the improved sock disclosed herein can be understood by examining the fit of a conventional sock compared to the fit of an embodiment of a sock with heel padding 14 on a foot of an individual wearing an oversized shoe. When wearing a conventional sock, the wearer must first position the conventional sock onto the desired foot and ensure that the toe area and heel pocket area of the sock adequately cover the respective areas of the foot. It may be necessary for the wearer to manually adjust the conventional sock onto the foot to maximize comfort. For example, excessive bunching or gathering of sock material in any one particular area can be minimized by pulling the sock up to obtain the best possible fit for the wearer's foot. This process of wearing the conventional sock into the ideal wearing position can be facilitated by using the reinforced sections of the toe area and heel pocket area, if present, as landmarks. It should be noted that the presence of these landmarks is optional since not all commercially available socks include this feature. After a suitable sock position on the foot is achieved, the wearer can then insert the outfitted foot into a respective shoe. It should be noted that the wearer can adjust or flex the various segments of his/her foot (e.g., forefoot, midfoot, and hindfoot) and ankle inside the shoe to ensure a comfortable resting position. When the wearer pushes his/her outfitted foot forward such that the toe area of the sock is in the proper position in the shoe, a gap 18 can be exposed between the rear of the conventional sock and the shoe counter 16, as shown in FIG. 1E. The use of an oversized shoe can result in a significant gap 18 in this area such that the overall fit is poor and the comfort level for the wearer is low. The poorly fitting shoe can lead to the foot slipping out of the shoe during activity or lead to the development of painful sores or abrasions.
When an individual wears an embodiment of the sock with heel padding 14, the wearer can position the sock with heel padding 14 into the target position allowing the heel padding 14 to cover a majority of the posterior aspect and portions of the medial and lateral aspects of the heel of the foot. As stated above, the wearer can make use of landmarks provided by the reinforced sections of the toe area 10 and heel pocket area 12 of the sock, if present. The presence of these landmarks is optional. After the desired positioning of the sock with heel padding 14 is achieved around the wearer's foot, the wearer can insert his/her outfitted foot into the respective shoe. As before, the wearer can adjust or flex the various segments of his/her foot (e.g., forefoot, midfoot, and hindfoot) and ankle inside the shoe to ensure a comfortable resting position. After pushing his/her outfitted foot forward such that the toe area 10 of the sock is in the proper position in the shoe, a reduced gap 18 b between the rear of the wearer's foot and the shoe counter 16 can be exposed, as illustrated in FIG. 1F. The reduced gap 18 b can be smaller than the gap 18 observed when wearing the conventional sock. In these embodiments, the combined thickness of the sock and heel padding 14 can be less than the width between the wearer's foot and the shoe counter 16. In other embodiments, the reduced gap 18 b can be absent, wherein the sock and heel padding 14 fills substantially the entire width between the rear of the wearer's foot and the shoe counter 16. The combined thickness of the sock and heel padding 14 can be approximately equal to or greater than the width between the rear of the wearer's foot and the shoe counter 16. Some benefits afforded to the wearer of an embodiment of the sock with heel padding 14 include an improved fit, an increased level of comfort, and a reduced tendency of the foot to slip out of its respective shoe. It should be noted that the embodiment of the sock with heel padding 14 and shoe depicted in FIG. 1F are of an athletic-type, however, the sock with heel padding and the benefits disclosed herein are contemplated for use with a plurality of different sock types in combination with a plurality of different shoe types.
An alternative embodiment of the sock assembly is shown in FIGS. 2A and 2B. In these embodiments, the heel padding 14 b can be a removable member that can be inserted into an attached pouch 30 to achieve the desired effect of adding cushioning to the rear area of the sock, as illustrated in FIG. 2A. In other embodiments, other retention devices, such as a pocket or sleeve can be used. The location of the pouch 30 with respective heel padding 14 b can be located in an area similar to that of the embodiment described above (i.e., primarily in the top half of the heel pocket area 12). Excessive exposure of the pouch 30 with respective heel padding 14 b towards the bottom half of the heel pocket area 12 is preferably avoided to prevent the likelihood of the pouch 30 and heel padding 14 b encroaching onto the plantar (bottom) surface of the foot upon wearing. Similar to the other embodiments described above, the wearer can manually adjust the pouch 30 with respective heel padding 14 b into the proper target orientation prior to placing the foot into a shoe. As noted in the embodiments above, the presence of marked reinforced sections for the heel pocket area 12 and toe area 10 are optional elements for the final manufactured version. The outline borders for these optional areas are shown with dashed lines in FIGS. 2A and 2B.
In some embodiments, the pouch 30 can be permanently attached to the rear area of the sock by any method now known or discovered in the future, such as sewing, hook and loop fasteners, snaps, adhesives, Velcro, etc. In embodiments where the pouch 30 is sewn to the sock, a plurality of different types of thread and a plurality of different types of stitching can be used. The pouch 30 can be coupled to the exterior of the sock or coupled to the interior of the sock. When worn, the sock with heel padding 14 b in its respective pouch 30 can provide adequate coverage of the rear of the foot as shown in FIG. 2B, similar to the coverage offered by embodiments of the sock with heel padding 14 described above.
In some embodiments, the heel padding 14 b can have a shape and dimensions similar to that disclosed for the first embodiment of the heel padding 14 discussed above. The pouch 30 can have an overall shape similar to its heel padding 14 b counterpart. The pouch 30 can also have a point of entry to allow for insertion of the heel padding 14 b. Preferably, the pouch 30 does not include a backing liner, although the inclusion of a liner made of any suitable natural or synthetic textile material can be allowable.
A point of entry 32 can be located on the superior margin of the pouch 30 to allow for insertion of the heel padding 14 b from the top after wearing the sock (FIG. 2B). The heel padding 14 b can alternatively be inserted into the pouch 30 prior to wearing the sock. Folding or manipulation of the heel padding 14 b may be required to facilitate its insertion into the pouch 30. Other shapes for the pouch 30 and alternative points of entry are also contemplated such that the final pouch 30 allows for the insertion of the heel padding 14 b.
Similarly, other shapes for the heel padding 14 b are contemplated that can be easily inserted into the pouch 30 by the wearer. Although the axes of symmetry as described above can be advantageous from a manufacturing perspective, some embodiments of the pouch 30 and of the heel padding 14 b need not possess axes of symmetry. The overall dimensions of the heel padding 14 b with associated pouch 30 can vary taking into account the size of the final manufactured product (e.g., a smaller padding member and pouch combination reserved for socks worn by children and a larger padding member and pouch combination reserved for socks worn by adults). The thickness of the heel padding 14 b can be at least approximately 0.125 inch (⅛ inch) and/or less than or equal to approximately 0.375 inch (⅜ inch), although other thicknesses are also contemplated. The thickness of the pouch 30 can be at least approximately 0.125 inch (⅛ inch) and/or less than or equal to approximately 0.25 inch (¼ inch), although other thicknesses are also contemplated.
In some embodiments, the final manufactured product can be offered to consumers in packaging containing multiple heel paddings 14 b of varying thicknesses (e.g., ⅛ inch, ¼ inch, and ⅜ inch thickness presentations) to allow the wearer the added flexibility to further customize the level of cushioning required to obtain the best shoe fit. A wearer can elect to use a single or any combination of heel paddings 14 b for insertion into the pouch 30. In some embodiments, the point of entry 32 on the pouch 30 can be closed, such as by the use of zippers, hooks, buttons, fasteners, snaps, or other closure devices.
The material of the heel padding 14 b of at least this alternative embodiment can be made of a flexible and durable material such as polyurethane foam. However, the use of other materials such as cotton, cotton-polyester blends, nylon, vinyl, rubber, leather, satin, suede, gel, silicone, fluid-filled material, Lycra, Spandex, plastic or any other natural or synthetic textile material are also contemplated. The pouch 30 can be made of various natural or synthetic textile materials, such as plastic, rubber, Lycra, Spandex, stretch fabrics, mesh, or other suitable material that would be able to accommodate one or more removable heel paddings 14 b.
The sock illustrated in FIGS. 2A and 2B is an athletic-type sock, but the pouch 30 and respective heel padding 14 b can be incorporated into any sock type (e.g., no-show, ankle, quarter, crew, over-the-calf, athletic, casual, dress, men's, women's, etc) or any sock size (e.g., infant, child, adolescent, adult, etc).
Another embodiment of the sock assembly is shown in FIG. 3A. In the illustrated embodiment, the heel padding 14 c covers a larger area of the back of the foot, for example spanning from the margin of the posterior, inferior aspect of the heel bone 2 and extending beyond the heel pocket area 12 so that the superior edge of the heel padding 14 c is disposed between the calcaneal insertion 4 of the Achilles tendon 6 and the shoe topline when the sock is worn by the wearer. This greater hindfoot coverage can allow the wearer the advantage of positioning the foot forward in the shoe for improving shoe fit while also providing an added cushioning element between the upper portion of the hindfoot and the upper portion of the shoe counter. Excessive exposure of the heel padding 14 c towards the bottom half of the heel pocket area 12 is preferably avoided to prevent the likelihood of the heel padding 14 c encroaching onto the plantar (bottom) surface of the foot upon wearing. Similar to the embodiments described above, the wearer can manually adjust the heel padding 14 c into the proper target orientation prior to placing the foot into the shoe. As noted in the embodiments above, the presence of marked reinforced sections for the heel pocket area 12 and toe area 10 can be optional elements for the final manufactured version of this alternative embodiment. Borders for these optional areas are shown with dashed lines in FIG. 3A.
In some embodiments of the sock assembly, the heel padding 14 c can be permanently attached to the sock by any method now known or discovered in the future, such as sewing, hook and loop fasteners, snaps, adhesives, Velcro, etc. In embodiments where the heel padding 14 c is sewn to the sock, a plurality of different types of thread and a plurality of different types of stitching can be used. The heel padding 14 c can be coupled to the exterior of the sock or coupled to the interior of the sock. In some embodiments, the heel padding 14 c can be an integrated component of the sock, such as for example where the heel padding 14 c is embedded in the sock.
In some embodiments, the heel padding 14 c can have a generally four-sided shape with two straight edges and two curved edges, as shown in FIG. 3B, with a line of symmetry 24 coincident to the sagittal plane of the foot when the sock is worn, as illustrated in FIG. 3A. This shape allows the final manufactured product the flexibility to be worn on either foot, similar to a conventional sock. The length along this line of symmetry 24 can be at least approximately 2 inches and/or less than or equal to approximately 4 inches in length. In other embodiments, the length of the line of symmetry 24 can be any other dimension. The curved margin along the superior edge when worn can be at least approximately 2 inches and/or less than or equal to approximately 4 inches in length, while the curved margin along the inferior edge when worn can be at least approximately 3 inches and/or less than or equal to approximately 5 inches in length. In other embodiments, the length of the margins along the superior and inferior edges can be any other dimension. Alternative shapes of the heel padding 14 c are also contemplated and the shapes need not possess an axis or axes of symmetry. The overall dimensions of the heel padding 14 c can vary taking into account the size of the final manufactured product (e.g., a smaller padding member reserved for socks worn by children and a larger padding member reserved for socks worn by adults). The thickness of the heel padding 14 c can be at least approximately 0.125 inch (⅛ inch) and/or less than or equal to approximately 0.375 inch (⅜ inch), although other dimensions are also contemplated.
In some embodiments, the material of the heel padding 14 c can be made of a flexible and durable material such as polyurethane foam. In other embodiments, the material can include other materials such as cotton, cotton-polyester blends, nylon, vinyl, rubber, leather, satin, suede, gel, silicone, fluid-filled material, Lycra, Spandex, or any other natural or synthetic textile material.
The sock illustrated in FIG. 3A is an athletic-type sock but the heel padding 14 c can be incorporated into any sock type (e.g., no-show, ankle, quarter, crew, over-the-calf, athletic, casual, dress, men's, women's, etc) or any sock size (e.g., infant, child, adolescent, adult, etc).
FIGS. 4A-4D illustrate alternative embodiments of the heel padding. For example, as illustrated in FIG. 4A, the heel padding 14 d can have a generally trapezoidal shape. In another example, the heel padding 14 e can have a generally rectangular shape, as illustrated in FIG. 4B. In some embodiments, the heel padding 14 f can have a generally triangular shape, as illustrated in FIG. 4C. In still other embodiments, the heel padding 14 g can have a generally circular shape, as illustrated in FIG. 4D. A line of symmetry 26, as shown in FIGS. 4A-4D, can be aligned coincident to the sagittal plane of the foot when the sock assembly is worn. Similar to the above described embodiments, the symmetrical feature of the heel paddings 14 d, 14 e, 14 f, 14 g can advantageously allow the final manufactured product to be worn on either foot, similar to a conventional sock.
In some embodiments, the length of the line of symmetry 26 can be at least approximately 1 inch and/or less than or equal to approximately 3 inches in length. In other embodiments, the length of the line of symmetry 26 can be any other dimension. Alternative shapes are also contemplated and need not possess an axis or axes of symmetry. The overall dimensions of the heel paddings can vary taking into account the size of the final manufactured product (e.g., a smaller padding member reserved for socks worn by children and a larger padding member reserved for socks worn by adults). The thickness of the heel paddings can be at least approximately 0.125 inch (⅛ inch) and/or less than or equal to approximately 0.375 inch (⅜ inch), although other dimensions are also contemplated. Similar to above embodiments, the material of the heel paddings can be made of a flexible and durable material such as polyurethane foam. In other embodiments, the material can include other materials such as cotton, cotton-polyester blends, nylon, vinyl, rubber, leather, satin, suede, gel, silicone, fluid-filled material, Lycra, Spandex, or any other natural or synthetic textile material.
Although certain embodiments, features, and examples have been described herein, it will be understood by those skilled in the art that many aspects of the methods and devices illustrated and described in the present disclosure may be differently combined and/or modified to form still further embodiments.
