Embodiments of the present disclosure relate to dance shoes.
Athletic shoes of all types are subject to great amounts of stress through repeated, cyclical loading caused by walking, running, and other activities. Dance shoes, however, are subject to unique stress combinations due to the repetitive, high impact levels associated with dancing. Male ballet dancers in particular experience an incredible amount of high impact loads since a male ballet dancer's routine involves a disproportionate amount of jumping on a hard surface which can be taxing on the dancer's body.
Many conventional dance shoes generally sacrifice support and/or shock absorption to provide a low-weight, low-profile shoe. For example, conventional dance shoes are made of a thin piece of cloth with little or no absorptive potential. Accordingly, current dance shoe materials generally cannot provide a range of response characteristics to different levels of pressure and impact. Conventional dance shoes may be aesthetically pleasing but are not properly calibrated for higher-impact levels. Although a stiffer, thicker shoe or insert may provide proper resiliency and performance for running or other high-energy activities, such a heavy (relatively), large-profile shoe is generally not well suited for ballet dancing (e.g., does not accentuate the contour and aesthetics of the foot, cumbersome, not-flexible enough, etc.). Accordingly, there is a need for a dance shoe assembly that can meet the needs of repetitious, high-intensity activities, such as jumping, without sacrificing comfort or performance.
Aspects of the present disclosure are directed generally toward dance shoes. As disclosed herein, a dance shoe, such as a ballet shoe, can include a flexible shoe body having a forefoot portion, a heel portion opposite the forefoot portion, and a midfoot portion between the heel portion and the forefoot portion. The dance shoe further includes an integrated heel member securely attached to the heel portion of the flexibly shoe body. The heel member includes a support member configured to receive a shock-absorbing member, and a top portion of the shock-absorbing member is softer than a bottom portion of the shock-absorbing member.
Various embodiments of the disclosure will now be described. The following description provides specific details for a thorough understanding and enabling description of these embodiments. One skilled in the art will understand, however, that the disclosure may be practiced without many of these details. Additionally, some well-known structures or functions may not be shown or described in detail, so as to avoid unnecessarily obscuring the relevant description of the various embodiments.
The terminology used in the description presented below is intended to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific embodiments of the disclosure. Certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.
References throughout the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment and included in at least one embodiment of the present disclosure. Thus, the appearances of the phrase “in one embodiment” or “in an embodiment” in various places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
The flexible shoe body 102 further includes a forefoot portion 108 towards the front of the dance shoe 100, a heel portion 112 towards the rear of the dance shoe 100, and a midfoot portion 110 in between. In some embodiments, the midfoot portion 110 can include a midfoot section 140 defined by a single piece of material separate from the piece of material comprising the rest of the flexible shoe body 102. The flexible shoe body 102 can connect to the midfoot section 140 by a first seam 144a and a second seam 144b. The midfoot section 140 allows greater flexibility of the dance shoe 100 between the forefoot portion 108 and the heel portion 112, especially throughout the midfoot portion 110.

As best shown in
The dance shoe 100 may further include one or more flexible traction pads 128 disposed at the bottom portion 106 of the flexible shoe body 102 to provide additional support and/or cushioning to the dancer's foot, especially at high-intensity impact points (e.g., the ball and heel of the foot). The traction pad(s) 128 may individually comprise one or more layers. The traction pad(s) 128 and/or traction pad layer(s) may be stitched, glued or otherwise attached to a bottom surface of the flexible shoe body 102. To provide better traction for the dancer, the traction pad(s) 128 can be textured with one or more grooves and/or protrusions along a bottom surface of the traction pad(s). The traction pad(s) 128 can be made of canvas, leather, rubber, neoprene and/or any other material that increases frictional forces between the traction pad(s) 128 and the ground.
In the illustrated embodiments, the dance shoe 100 has a front traction pad 130 and a rear traction pad 132 such that the midfoot portion 110 of the dance shoe 100 is defined by the more flexible material of the flexible shoe body 102. Having separate front and rear traction pads 130, 132 allows the dance shoe 100 to flex at the midfoot portion so as to facilitate maintaining close proximity between a bottom region of the midfoot portion 110 and the dancer's foot, particularly when the foot is flexed. In other embodiments, the dance shoe 100 may have only a front traction pad 130, only a rear traction pad 132, or in some embodiments, the dance shoe 100 may not include any traction pads. The front traction pad 130 and rear traction pad 132 can be the same or different shapes. The front and rear traction pads 130, 132 can also provide increased cushioning and/or shock-absorption for the dancer by selected traction pad thickness, layering, and/or material composition. For example, the rear traction pad 132 can have a thickness of generally between about 1 mm and 4 mm (e.g., about 2 mm, about 3 mm), while the front traction pad 130 can generally have a thickness less than 1 mm. As such, when the dance shoe 100 is on the dancer's foot but not under the weight of the dancer, the bottom layer of the dance shoe 100 (e.g., the bottom portion of the flexible shoe body 102 and/or the traction pad 128) has a thickness of less than or equal to 4 mm (e.g., less than 3 mm, less than 2 mm, 0.5 mm, etc.).

The support member 402 has a bottom region 406 and a top region 408 extending upwardly from the periphery of the bottom region 406, as shown in
As best shown in
Different regions of the shock-absorbing member 404 can have different indentation force deflection (“IFD”) values. IFD values correspond to the softness and/or firmness of the shock-absorbing member 404 and/or regions of the shock-absorbing member 404. The softer and/or less firm the region of the shock-absorbing member 404, the lower the IFD value. In some embodiments, the shock-absorbing member 404 can have increasing IFD values as the height H2 of the shock-absorbing member 404 decreases. In other words, a top portion of the shock-absorbing member is softer and/or less firm than a bottom portion of the shock-absorbing member 404. Additionally, in some embodiments the bottom region 414 of the shock-absorbing member 404 can be generally more firm (e.g., higher IFD values) than the heel wrap 416. That way, the heel wrap 416 provides additional cushioning and/or shock-absorption, while the bottom region 414 provides additional support and stability (but also provides additional cushioning and/or shock-absorption).
In some embodiments, the layers may individually have different and/or the same IFD values so that a top portion of the shock-absorbing member 504 is softer and/or less firm than a bottom portion of the shock-absorbing member 504. For example, the top layer 506 can have a top layer IFD value that is less than an intermediate layer IFD value, and the intermediate layer IFD value can have a smaller IFD value than the bottom layer IFD value. In another embodiment, the top layer 506 can have a top layer IFD value that is the same as the intermediate layer IFD value, and the intermediate layer IFD value can have a smaller IFD value than the bottom layer IFD value. In particular embodiments, the top layer 506 can be made of memory foam, while the intermediate layer 508 and bottom layer 510 can be made of slow recovery foam of varying thicknesses.
In some embodiments, the layers may individually have different thicknesses. For example, the bottom layer thickness BT can be greater than the intermediate layer thickness IT, and the intermediate layer thickness IT can be greater than the top layer thickness TT. In some embodiments, the layers may individually have different widths and/or shapes. For example, as shown in
