DETAILED DESCRIPTION OF THE DRAWINGS
(13) In the following discussion that addresses a number of embodiments and applications of the present invention, reference is made to the accompanying drawings that form a part hereof, where depictions are made, by way of illustration, of specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and changes may be made without departing from the scope of the present invention.

(15) For the purposes of simplicity, the foot can also be categorized into its relative regions: the hindfoot, midfoot, and forefoot, listed from proximal to distal end. The hindfoot comprises calcaneus 112 and talus 106. The midfoot comprises five important bones, two of which are cuboid 114 and navicular 108, and three of which are cuneiforms 110, together outlining the area of interest: the arch region. The forefoot comprises metatarsals 116, which are the five bones connecting the midfoot to the toe bones, and the toe bones themselves, referred to as phalanges 118. The hallux has two phalanges 118, whereas the remaining four toes are comprised of three phalanges 118. Tibia 104 and fibula 102 do not make up part of foot 100 and are instead long bones of the lower leg, though both tibia 104 and fibula 102 impact and are impacted by the arch region and its constituents.

(17) Arch support assemblage 250, in accordance with the present exemplary embodiment displayed in
(18) In alternative embodiments, arch support assemblage 250 may cover a slightly larger area of foot 100, perhaps to the vertical boundary between the third and fourth toes, so as to more completely encompass arch region 230. However, even in such wider-reaching embodiments, a disproportionate amount of support is offered to the inner half of foot 100 as compared to the outer half.
(19)
(20) As a result of the lowered energy demand for erect posture and movement, an arch support assemblage is also useful for persons with normal foot arches. While foot maladies are more likely to occur among those with structural difficulties or deficiencies in the foot or leg, they also occur in persons with no such difficulties or deficiencies, for example when beginning a more rigorous exercise regimen or running long distances on pavement or concrete. Furthermore, such difficulties as flat feet, elaborated upon in the discussion of

(22) Sock 436 disclosed in
(23) Still referring to
(24) Each of the following figures describes the various parts, features, designs, and purposes of the proposed arch-supporting sock.
(25) The sock material is an important feature of the invention. The stiff, reinforcing region of the arch is not specific to a particular type of sock, and as such, can be made for any occasion, formal or informal, athletic, or otherwise. For instance, the sock may be made for the purposes of walking, running, skiing, snowboarding, working, hiking, or backpacking, though the enumerated purposes are by no means exhaustive. As a result of the various purposes wherein a person might find the invention of use, the sock can also comprise a myriad of materials. By way of just a few non-limiting examples, wool, polyester, cotton, acrylic, nylon, and cashmere may be utilized.
(26) Sock instep 444 refers to the top region of sock 436 which overlays arch region 230 and arch support assemblage 442 but is not in contact with support assemblage 442 when foot 100 is inside sock 436. Arch support assemblage 442 rests in front of heel flap 440 and behind sock toe 446 and comprises a denser weave than the remaining regions of sock 436, although it does not employ the oft-used terry loops, as the terry loop weave is much better fit for cushioning than providing structural support and stability. Rather, in one non-limiting embodiment, arch support assemblage 442 may employ tuck stitching to achieve a denser weave in which a given sock segment may have multiple rows of stitching overlain. The proposed arch-supporting sock may employ terry loops elsewhere in the sock, where perhaps support and stability are not the goal. Accordingly, arch support assemblage 442 is stiffer than any other part of the sock, though stiffness may vary within arch support assemblage 442 due to differences in strain between parts of the arch. The arch or arch region 230, unless specified as a particular arch, such as transverse arch 224, is to be construed as the region falling on or within the confines of medial longitudinal arch 228, lateral longitudinal arch 226, and transverse arch 224.

(34) Among the shorter sides of arch support assemblage 442, with sock toe 446 considered to be the distal-most region and sock leg 438 considered the proximal-most region, a third perimetric boundary or transverse support 852 lies distal to a fourth perimetric boundary or heel support 854. In exemplary embodiments, transverse support 852 roughly extends along transverse arch 224, though other embodiments exist in which transverse support 852 is distal to transverse arch 224 and may more closely outline the boundary between the metatarsals and phalanges. Also in exemplary embodiments, heel support 854 roughly contours the distal end of heel 332 in the approximate region where the midfoot begins and hindfoot ends. Without deviating from the spirit or scope of the present invention, heel support 854 may also begin near the center of heel 332, with reference the length and not the width of sock 436. In the embodiment pictured in
(35) In the present disclosure, elasticity coefficient generally refers to the ratio of acutely endured stress to the temporary change in conformation of an elastic entity, whereby for example, an entity with a low elasticity coefficient would be less flexible, pliable, or otherwise physically influenced than an entity with a high elasticity coefficient, assuming equal stress is applied.
(36) The illustrated embodiment comprises medial longitudinal support 848, lateral longitudinal support 850, and transverse support 852 with lower elasticity coefficients than both heel support 854 and most or the rest of arch support assemblage 442 bound within the perimetric supports 848, 850, 852, 854. Parts of the arch-supporting sock having comparably lower elasticity coefficients will be more stiff and obdurate, that is resistant to physical manipulation or persuasion, and resultantly more stable and supportive of the corresponding regions of the foot resting upon these sock regions than will those parts with comparably higher elasticity coefficients. Accordingly, in these embodiments, the arch-supporting sock is able to stabilize and support the entirety of arch region 230, also referred to as the arch, as defined roughly by the dashed lines in
(37) The difference of elasticity around and within the perimetric boundary of arch support assemblage 442 may be achieved in any number of ways. For example, and without limiting the scope of the present invention, arch support assemblage 442 is bound within the perimetric boundaries or perimetric supports 848, 850, 852, 854 and may comprise different knitting or stitching techniques known in the art, such as tuck-stitching, implemented in a manner so that arch support assemblage 442 comprises an increased weight, width, or thickness.
(38) Other embodiments may comprise of perimetric supports which have elasticity coefficients less than most or the rest of sock 436. For instance, in one embodiment, the supports with the lowest elasticity coefficients are medial longitudinal support 848 and lateral longitudinal support 850, with transverse support 852 and heel support 854 registering elasticity coefficients roughly equal to that of the rest of arch support assemblage 442. Still other embodiments may, for example, provide the lowest elasticity coefficient levels around the entire perimeter of arch support assemblage 442, which comprises medial longitudinal support 848, lateral longitudinal support 850, transverse support 852, and heel support 854.
(39) In one embodiment, only medial longitudinal support 848 will have a lower elasticity coefficient than each other part of the sock to account for the expectation that medial longitudinal support 848 will endure the greatest pressure while the user displays an erect posture.
(40) In another embodiment, the perimetric supports may consist of varying elasticity coefficients generally based either on typical pressure expectations of the three arches and the distal heel region, or on the specific needs of persons with such aforementioned maladies as plantar fasciitis or a flat arch, among other maladies that would be known by those skilled in the art.
(41)
(42) An arch-supporting sock has been described. The foregoing description of the various exemplary embodiments of the invention has been presented for the purposes of illustration and disclosure. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention not be limited by this detailed description, but by the claims and the equivalents to the claims.
