DETAILED DESCRIPTION

[0017] An embodiment of a shoe in accordance with the present disclosure is indicated by reference numeral 20 in Figures 1-7. The shoe 20 includes a sole, generally indicated at 22, an upper, generally indicated at 24, and a chassis member, generally indicated at 26. The sole 22 and chassis member 26 are secured to the upper 24. The shoe 20 extends forward from a heel end 28 to a toe end 30. The upper 24 has a knitted element 32. In alternative embodiments, the upper 24 is constructed of fabric and/or other materials and may or may not be of a unitary construction.

[0018] The knitted element 32 is formed of a unitary one-piece construction during a knitting process on a knitting machine. The knitted element 32 includes a knitted tongue region 34, a knitted upper heel region 36, a knitted upper lateral midfoot region 38, a knitted upper medial midfoot region 40, a knitted upper metatarsal region 42, a knitted upper lateral ball region 44, a knitted upper medial ball region 46, and a knitted upper toe region 48. The upper

metatarsal region 42 includes a knitted upper lateral metatarsal region 50 and a knitted upper medial metatarsal region 52. The upper has a knitted upper lateral side region 54 and a knitted upper medial side region 56. The upper lateral side region 54 includes the upper lateral midfoot region 38, the upper lateral metatarsal region 50, and the upper lateral ball region 44. The upper medial side region 56 includes the upper medial midfoot region 40, the upper medial metatarsal region 52, and the upper medial ball region 46. The upper toe region 48 is seamlessly knitted with the upper medial and lateral ball regions 46, 44 during the knitting process. The upper medial and lateral ball regions 46, 44 are seamlessly knitted with the upper metatarsal region 42 during the knitting process. The upper metatarsal region 42 is seamlessly knitted with the upper lateral and medial midfoot regions 38, 40 during the knitting process. The knitted upper tongue region 34 is seamlessly knitted with (1) the knitted upper toe region 48; (2) the knitted upper lateral side region 54; and (3) the knitted upper medial side region 56. The seamless knitting of the various regions provides a bootie like construction and including an integrated tongue. In alternative embodiments, the upper 24 has a tongue that is not integrated (e.g., the tongue is attached to the upper about a toeward side and is free along at least a portion of a medial side and at least a portion of a lateral side).

[0019] The shoe 20 includes a lacing system 58. The lacing system 58 comprising a medial side eyestay 60 and a lateral side eyestay 62. The medial side eyestay 60 and the lateral side eyestay 62 are joined by a transverse portion 64 of the lacking system 58. In alternative embodiemnts, the medial side eyestay 60 and the lateral side eyestay 62 are separated. The medial side eyestay 60 includes a plurality of medial side eyelets 66, and the lateral side eyestay 62 includes a plurality of lateral side eyelets 68. The eyelets 66, 68 may be openings (e.g., in a tear resistant material such as leather), may be partially defined by grommets coupled to the upper 24, or may be other suitable openings adapted and configured to receive a shoelace. The medial 60 and lateral eyestays 62 are configured such that a single shoelace

70 can be placed through each of the plurality of lateral 68 and medial side eyelets 66 without extending through the knitted element 32. The shoelace 70 is threaded through the medial side eyelets 66 and the lateral side eyelets 68 such that the shoelace overlies the knitted element 32 without passing through the knitted element.

[0020] To provide for this lacing configuration, the medial side eyelets 66 include a plurality of medial eyelet pairs 72. Each eyelet of the medial eyelet pair 72 is spaced apart transversely and spaced apart longitudinally. The shoelace 70 enters the medial eyestay 60 through one eyelet of the medial eyelet pair 72 and exits through the other eyelet of the medial eyelet pair. Each eyelet pair 72 of the plurality of medial eyelet pairs is spaced apart longitudinally. The lateral side eyelets 68 include a plurality of lateral eyelet pairs 74. Each eyelet of the lateral eyelet pair 74 is spaced apart transversely and spaced apart

longitudinally. The shoelace 70 enters the lateral eyestay 62 through one eyelet of the lateral eyelet pair 74 and exits through the other eyelet of the lateral eyelet pair. Each eyelet pair 74 of the plurality of lateral eyelet pairs is spaced apart longitudinally.

[0021] The medial side eyelets 66 do not overlap longitudinally. For example, the two eyelets in the medial eyelet pair 72 are spaced longitudinally from each other. In alternative embodiments, adjacent medial eyelets 66 may overlap longitudinally while being spaced transversely. The same is true for the lateral side eyelets 68. In some embodiments, each medial side eyelet 66 is substantially similar in size, and the medial eyelets of each medial eyelet pair 72 are spaced apart longitudinally by a length substantially equal to a longitudinal length of one of medial side eyelets 66. In alternative embodiments, the spacing may be greater than a single length of the one medial side eyelet 66. The same is true for the lateral side eyelets 68 and lateral side eyelet pairs 74.

[0022] The medial eyestay 60 and the lateral eyestay 62, along with the transverse portion 64, form a U-shaped panel. The panel has an interior edge margin 76 and an exterior edge

margin 78. The interior edge margin 76 faces a centerline of the upper, and the exterior edge margin 78 faces away from the centerline of the upper. The panel is stitched to the knitted element 32 in the exterior edge margin 78. In some embodiments, the panel is also stitched to the knitted element 32 in the interior edge margin 76.

[0023] The eyelets 66, 68 and the shoelace 70 are positioned such that the shoelace 70 partially overlies the medial eyestay 60, and the medial eyestay partially overlies the shoelace. The shoelace 70 also partially overlies the lateral eyestay 62, and the lateral eyestay partially overlies the shoelace. The shoelace 70 overlies the inner edge margin 76 of the medial eyestay 60, and the shoelace overlies the inner edge margin of the lateral eyestay 62. The inner edge margin 76 of the medial eyestay 60 does not overlap the shoelace 70, and the inner edge margin of the lateral eyestay 62 does not overlap the shoelace.

[0024] The depicted embodiment illustrates the shoe 20 with a knitted upper 24 and leather medial 60 and lateral eyestays 62. In alternative embodiments not depicted, the materials of the shoe 20 may differ. For example, and without limitation, the upper 24 may be fabric, polymer, leather, or the like (of unitary or dispersate construction). The medial 60 and lateral eyestays 62 may be fabric, polymer, knitted, or the like.

[0025] In view of the foregoing, it should be appreciated that the shoe of the disclosure has several advantages over the prior art.

[0026] As various modifications could be made in the constructions and methods herein described and illustrated without departing from the scope of the disclosure, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative rather than limiting. For example, the wedge shoe may be any type of wedge shoe, such as a wedge sandal, a wedge pump, an open-toe wedge, a platform wedge, etc. Thus, the breadth and scope of the present disclosure should not be

limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims appended hereto and their equivalents

[0027] It should also be understood that when introducing elements in the present disclosure in the claims or in the above description of exemplary embodiments of the disclosure, the terms“comprising,”“including,” and“having” are intended to be open-ended and mean that there may be additional elements other than the listed elements. Additionally, the term “portion” should be construed as meaning some or all of the item or element that it qualifies. Moreover, use of identifiers such as first, second, and third should not be construed in a manner imposing any relative position or time sequence between limitations.
