DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
[0028] While various aspects and features of certain embodiments have been summarized above, the following detailed description illustrates a few exemplary embodiments in further detail to enable one skilled in the art to practice such embodiments. The described examples are provided for illustrative purposes and are not intended to limit the scope of the invention.
[0029] In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the described embodiments. It will be apparent to one skilled in the art, however, that other embodiments of the present invention may be practiced without some of these specific details. Several embodiments are described herein, and while various features are ascribed to different embodiments, it should be appreciated that the features described with respect to one embodiment may be incorporated with other embodiments as well. By the same token, however, no single feature or features of any described embodiment should be considered essential to every embodiment of the invention, as other embodiments of the invention may omit such features.
[0030] In this application the use of the singular includes the plural unless specifically stated otherwise, and use of the terms and and or is equivalent to and/or, also referred to as non-exclusive or unless otherwise indicated. Moreover, the use of the term including, as well as other forms, such as includes and included, should be considered non-exclusive. Also, terms such as element or component encompass both elements and components comprising one unit and elements and components that comprise more than one unit, unless specifically stated otherwise.
[0031] The invention provides an elegant and stylish high-heeled shoe that includes improved arch supports, pads, and gel-filled cushions to enhance ankle stability and wearer comfort and improved weight distribution, by collecting and transferring body weight primarily by the ball of the heel and secondarily by an arch support and tertiarily by a toe ridge. These distributed support structures in combination prevent an undesirable feeling of the foot sliding down the ramp.
[0032] For all figures, reference numerals and reference letters for elements described in any one figure represent the same elements as they appear and are referenced in any other figures, without requiring redundant recitation of the same description in those other figures.
[0033] Referring to the figures,
[0034] In this specification the term positive curvature is used to define curved lines and surfaces which at their lateral portions bend away from a theoretical viewer, such as the outside surface of a can or a ball. The term negative curvature is used to define curved lines and surfaces which at their lateral portions bend toward a theoretical viewer, such as the inside surface of a can or a ball. The descending portion of the throat includes a transverse line of inflection [N] where the shoe surface transitions from negative curvature such as in the vicinity of the heel cup, to positive curvature such as the throat of the shoe beneath the wearer's arch. The reference numeral [lb] in this figure defines the portion of the shoe shown in
[0035]
[0036]
[0037]
[0038] A first exemplary pattern of fastener receiving apertures [5] is shown as a preferred arrangement and a second pattern of apertures [5] is also shown as an alternate embodiment. Other arrangements of these apertures also reside within the scope of the invention. According to alternative embodiments also residing within the scope of the invention, the contour [G] of the shoe tip may extend past the toes of the wearer to converge partially or completely to a point or a rounded point, and the toe strap or toe box may be open or closed at the tip. The shoe as an assembly also includes a shank component embedded within the outer sole or the insock component, such as by insert molding. The shank is optionally transfixed by at least one fastener which would seat in aperture [4] in this figure. Additional fasteners for securing the shank within the shoe assembly may also be located in the throat section of the shoe assembly.

[0042]
[0043] Also, in embodiments (such as an example seen in
[0044] The outer sole of the inventive shoe component defines a heel cup [16] having a transverse width dimension [w] and with a depth dimension [d] defined from a point within 15% of a true midpoint [w/2] of a line extending across the lateral ridges of the heel cup as seen in this cross section view. According to a preferred embodiment, this depth is at least 17% of the transverse width dimension, so that lateral stability and comfort is supplied to the heel and especially the medial process of the calcaneus bone. According to a preferred embodiment the depth of the cup is between 5 mm and 15 mm.
[0045]
[0046]
[0047] A second slope [S.sub.A] may be defined as an angle from horizontal to a line [S] passing through a first point in this sagittal plane at a rearmost ground contact point of a ground contact region of the shoe proximal to the pocket and a second rearmost point of the outer sole in this sagittal plane proximal to the undercut for the heel counter. The distance from the support axis of the heel pillar to the first point is [S.sub.L,] and the height from ground to the second point is [S.sub.H,] and the first angle [S.sub.B] with respect to horizontal that is less than the second slope [S.sub.A.]
[0048] According to a best mode as illustrated, the second slope [S.sub.A] is about 40.5? in this figure, and first angle [S.sub.B] is about 21.5?. The invention is practicable with [S.sub.A] being within a range spanning inclusively from at least about 35? to about 60? as a maximum value, and with the first angle [S.sub.B] being within a range spanning inclusively from at least about 10? to about 40? as a maximum value, but so that the heel pocket forms a ramp angle being the difference of angle [S.sub.A] minus angle [S.sub.B] and with this ramp angle being within a range spanning inclusively from at least about 10? to about 30? as a maximum value. In this specification, the word about when referencing a numerical value may be taken to mean an actual value within a range spanning inclusively between 10% above and 10% below the numerical value.
[0049] A dowel [13] which may be made of metal such as steel, aluminum, or brass, is disposed partially within the heel pillar and partially within the top lift [8] beneath the heel pillar. The top lift is preferably made of hard or tough material, wherein hardness is defined as resistance to indentation and toughness is defined as endurance or resistance to erosion by abrasion. The top lift may also be a composite structure comprising soft plastic or hard rubber. The top lift may also be overmolded onto the dowel.
[0050] The outer sole further defines a heel cup and a throat section connected by a negatively curved surface at a transition surface [12] proceeding from the heel cup to the throat section of the insole, optionally and preferably in the form of a negatively curved, or saddle-shaped 3-dimensional surface.
[0051] Other unimproved designs usually include just a simple, axial bend which results in a laterally flat transverse ridge which is less comfortable to wear when standing. According to another embodiment within the scope of the invention, the shank may be insert-molded without the use of fasteners or rivets. According to yet another embodiment within the scope of the invention, the reinforcing column is made shorter than the length of the heel pillar so that it stops short, recessed within the heel pillar, and forms a downward pointing aperture, and a top lift complementary to this particular embodiment includes a protruding dowel which may be insert molded into the top lift. The protruding portion of this dowel is received within the downward-pointing aperture and coaxially abuts to the reinforcement column in the heel pillar. The dowel partially protrudes from the heel pillar, and the top lift is affixed to the dowel.
[0052] In the exemplary embodiment as shown, the dowel is abutted to and coaxial to the reinforcement column in the heel pillar and partially protrudes from the heel pillar, and the top lift is affixed to the dowel.
[0053] According to yet other embodiments within the scope of the invention, an outer sole may further comprise a downwardly protruding stud [32] coaxially aligned with the support axis of the heel pillar. Additional cosmetic components for the shoe include membranes of material which shroud the heel pillar. The membranes may include fabric, leather, or synthetic materials. One rear membrane [27] resembles the fantail of a ship, and its forward edges join to a second membrane [28] which extends beneath the outer sole and the forward tread area of the shoe.
[0054]
[0055]
[0056] According to preferred embodiments, the insock comprises a first shock-absorbing gel pad and a second component comprising high-rebound memory foam affixed atop the gel pad, both sandwiched between fabric layers adhered to each other by an adhesive. The pads may then be covered by a pad cap [21] which is a membrane of material that aesthetically matches the rest of the insock of the shoe. The insock may be secured to the outer sole [2] by adhesive or by mechanical means such as stitching, so that the gel pad is registered within the pocket of the outer sole. The rear ridge of the gel pad bolsters the wearer's foot by supplying reaction forces counteracting longitudinal forces within the foot which would otherwise allow the foot to slide down the throat section of the outer sole. Another substantial portion of these longitudinal forces is taken up by the forward rim of the heel cup.
[0057] The insock of this high-heeled shoe further comprises a second, semilunar pad component [22] located partway along the throat of the insock so that it resides beneath the instep of the wearer's foot as an additional feature for collecting longitudinal forces in the foot and eliminating an unwanted feeling of sliding down a ramp. The relative geometry of the two slopes [S.sub.A] and [S.sub.B] as discussed in
[0058] Besides furnishing shoes in given or standard sizes, a shoe of a selected size may also be customized by request to include arch support pads selected from a variety of shapes, thicknesses, durometer, and contours so that a manufacturer may offer tailored products uniquely and specifically formed to particular customers.
[0059]
[0060]
[0061]
[0062]
[0063] The ornamental ankle bracelet is detachable from the heel counter. In the embodiment shown, the heel counter includes a loop feature which is a closed loop and the ornamental ankle bracelet passes through the loop. The ornamental ankle bracelet in this example includes a closure which is a buckle, which allows the closed loop of the ornamental ankle bracelet to be opened and removed from the closed loop of the heel counter. An alternate arrangement within the scope of the invention includes that the loop feature of the heel counter is an openable and closable clasp, which may enclose both the type of ankle bracelet having an openable and closable clasp or buckle of its own and also may enclose an alternative type of ornamental ankle bracelet which is a continuous and closed loop. The loop feature of the heel counter may also be designed large enough to enclose two or more ankle bracelets to be worn concurrently.
[0064] In both types of embodiments as described, the user may over time or in an initial purchase of the shoes acquire a set consisting of a plurality ornamental ankle bracelets associated with the shoe, and alter the appearance of the shoe by selecting any one or more from the plurality of ornamental ankle bracelets. Thus, the user may adapt the appearance of the shoe at whim to conform to ephemeral fashion trends or to signal participation with social movements which have recognized indicia by acquiring and configuring the shoe to display an ornamental ankle bracelet conforming to the latest fashion or bearing the indicia associated with a personage, celebrity, sports or entertainment franchise, political affiliation or protest thereof, or any cause of the day.
