An embodiment of a shoe in accordance with the present disclosure is indicated by reference numeral 10 and is illustrated in
The knitted element 20 is formed of a unitary one-piece construction during a knitting process on a knitting machine (not shown). The knitted element 20 includes a knitted upper heel region 22, a knitted upper lateral midfoot region 24, a knitted upper medial midfoot region 26, a knitted upper metatarsal region 28, a knitted upper lateral ball region 30, a knitted upper medial ball region 32, and a knitted toe region 34. The knitted toe region 34 includes a knitted upper toe region 36 and a knitted lower margin region 38. The knitted lower margin region 38 is adjacent the sole 12 and within the knitted toe region 34. The knitted lower margin 38 extends upwardly from the sole 12. The knitted lower margin region extends from a lateral side 40 of the shoe to the toe end 19 of the shoe and from the toe end 19 of the shoe to a medial side 42 of the shoe. In other words, the knitted lower margin 38 is a band that extends around the lower portion of the toe region 34. The knitted lower margin 38 may extend toward the heel end 18 further than at least a portion of the throat region 44 in which the upper 14 is laced.
The knitted upper toe region 36 is adjacent the knitted lower margin region 38 and extends laterally across the shoe 10. The upper metatarsal region 28 includes a knitted upper lateral metatarsal region 46 and a knitted upper medial metatarsal region 48. The upper has a knitted upper lateral side region 50 and a knitted upper medial side region 52. The upper lateral side region 50 includes the upper lateral midfoot region 24, the upper lateral metatarsal region 46, and the upper lateral ball region 30. The upper medial side region 52 includes the upper medial midfoot region 28, the upper medial metatarsal region 48, and the upper medial ball region 32. The toe region 34 is seamlessly knitted with the upper medial and lateral ball regions 30, 32 during the knitting process. The upper medial and lateral ball regions 30, 32 are seamlessly knitted with the upper metatarsal region 28 during the knitting process. The upper metatarsal region 28 is seamlessly knitted with the upper lateral and medial midfoot regions 24, 26 during the knitting process. The knitted lower margin 38 of the knitted toe region 34 is of a different knit structure than at least the knitted upper toe region 36 such that the knitted lower margin 38 of the knitted toe region resists stretching of the knitted upper 14 and is more resilient than at least some other portions of the knitted toe region (e.g., the heel region 22). For example, and without limitation, the resiliency may allow for the shoe 10 to better keep its shape with and/or without a foot within the shoe 10. The knitted lower margin 38 may have greater cohesion than the upper toe region 36, cohesion being the resistance of a section of the knitted element to being pulled apart. In other words, a section of the knitted element with greater cohesion will more strongly resist separation between adjacent stitches when the knitted element is under a load (e.g., stretched).
The knitted element 20 is comprised of substantially the same yarn throughout. The yarn being substantially the same in that it has the same or substantially the same mechanical properties, shape, consistency, or the like. The yarn can vary in color and type of stitch throughout the knitted element 20 while still being substantially the same throughout. In some embodiments, the knitted element 20 is a single layer. The difference of cohesion is achieved through the use of different stitch densities (e.g., gauges or stitches per area) because at least some other factors which impact the stretchiness of the knitted element are fixed as a result of the use of a single layer and substantially the same yarn throughout the knitted element 20.
In some embodiments, the lower toe margin 38 is knitted using a first stitch (e.g., a jersey stitch) while the entirety of the knitted element 20 other than the lower toe margin 38 is knitted from a second, different, stitch (e.g., a pointelle stitch). The increased cohesion in the lower toe margin 38 is a result of the jersey stitch and/or a higher stitch gauge.
In some embodiments, the knitted lower margin 38 of the knitted toe region 34 has a first knit structure having a first gauge, and the knitted upper toe region 36 has a second knit structure having a second gauge. The first gauge larger than the second gauge (e.g., there are more stitches per given area in the lower margin 38 than in the upper toe region 36). The first knit structure is of a first type of stitch, and the second knit structure is of a second type of stitch. For example, and without limitation, the first knit structure is comprised of jersey stitches and the second knit structure is comprised of pointelle stitches as depicted in
In alternative embodiments, the first knit structure comprises a first type of stitch and the second knit structure also comprises the first type of stitch. For example, and without limitation, the lower margin 38 and the upper toe region 36 are both knitted using the same jersey stitch. To provide for greater cohesion in the lower margin 38, the lower margin 38 is knit with a larger gauge (e.g., more stitches per unit area). This provides greater support in the lower margin 38 and causes the lower margin 38 to resist stretching to a greater degree than other areas of the upper 14. Advantageously, this supports a user's foot when the shoe 10 is worn.
The knitted lower margin 38 may differ from one or more other regions of the shoe 10. For example, the knitted lower margin 38 of the knitted toe region 34 has a first knit structure having a first gauge. The knitted upper lateral midfoot region 24, the knitted upper medial midfoot region 26, the knitted upper metatarsal region 28, the knitted upper lateral ball region 30, and the knitted upper medial ball region 32 has a second knit structure having a second gauge. The first gauge is larger than the second gauge. In some embodiments, the knitted upper heel region 22 has a third knit structure. The third knit structure as a third gauge, with the third gauge being larger than the second gauge.

The knitted element 120 is seamlessly knit to include a heelward wingtip section 137 and a toeward wingtip section 139. The heelward wingtip section 137 and the toeward wingtip section 139 meeting at a wingtip line 141. The wingtip line 141 has a medial line portion 143 and a lateral line portion 145. The medial line portion 143 includes a wing-shaped curved line 147 extending forward from at least the upper medial metatarsal 148 region to the upper toe region 134 and a central line 149 extending rearward from the upper toe region 134. The lateral line portion 145 includes a wing-shaped curved line 151 extending forward from at least the upper lateral metatarsal region 146 to the upper toe region 134 and a central line 153 extending rearward from the upper toe region 134. The rearwardly extending central line 149 of the medial line portion 143 converges toward the rearwardly extending central line 153 of the lateral line portion 145 and the two meet at a heelward facing point 155. The heelward wingtip section 137 is adjacent the wingtip line 141 and extends longitudinally toward the knitted upper heel region 122. The toeward wingtip section 139 is adjacent the wingtip line 141 and extends longitudinally toward the knitted upper toe region 134.
The toeward wingtip 139 section has a first gauge, and the heelward wingtip section 137 has a second gauge. The first gauge is larger than the section gauge. This difference in gauges causes the upper 14 to support a user's foot while also allowing for breathability and stretching in the heelward wingtip section 137. The toeward wingtip section 139 and the heelward wingtip section 137 are constructed of the same stitch type. For example, and without limitation, both the toeward wingtip section 139 and the heelward wingtip section 137 are constructed of the same jersey stitch. The heelward wingtip section 137 does not extend within the upper medial midfoot region 126 and does not extend within the upper lateral midfoot region 124. The toeward wingtip section 139 does not extend within the upper medial midfoot region 126 and does not extend within the upper lateral midfoot region 124. In some embodiments, the toeward wingtip section 139 is uniform and the heelward wingtip section 137 is uniform. For example, and without limitation, the toeward wingtip section 139 and the heelward wingtip section 137 are devoid of broguing within the section.
The knitted element 120 may include in each of the upper medial metatarsal region 148 and the upper lateral metatarsal region 146 an area 157, 159 respectively of the knitted element 20 having a third gauge. The third gauge is smaller than the first gauge and the second gauge. In such a case, the toeward wingtip section 139 is of a first knit structure having a first stitch type, and the area(s) 157, 159 of the knitted element having a third gauge is of a second knit structure having a second stitch type. For example, and without limitation, the toeward wingtip section 139 is constructed of a jersey stitch and the area(s) 157, 159 having the third gauge is constructed of a pointelle stitch. These features provide for flexibility and breathability in the metatarsal region 128 while the toeward wingtip section 139 and/or the heelward wingtip section 137 provide for stability and support. These areas 157, 159 may also extend within the medial ball region 132 and the lateral ball region 130, respectively.
In alternative embodiments, the toeward wingtip section 139 is constructed of a first knit type and the heelward wingtip section 137 is constructed of a second knit type. For example, and without limitation, the toeward wingtip section 139 is constructed of a jersey stitch and the heelward wingtip section 137 is constructed of a pointelle stitch.
The knitted element 120 of the shoe 110 further includes a medial area 161 and a lateral area 163. The medial area 161 is in at least the upper medial midfoot region 126, and the lateral area 163 is in at least the upper lateral midfoot region 124. The lateral area 161 and the medial area 163 are of a knit structure having the first gauge (e.g., the same gauge as the toeward wingtip section 139) or the second gauge (e.g., the same gauge as the heelward wingtip section 137).
The knitted element 120 further includes a second medial area 165 and a second lateral area 167. The second medial area is in at least the upper medial midfoot region 126 and is adjacent the medial area 161. The second medial area is of a knit structure having a gauge smaller than the first gauge and/or smaller than the second gauge. The second lateral area 167 is in at least the upper lateral midfoot region 124 and is adjacent the lateral area 163. The second latera area 167 is of a knit structure having a gauge smaller than the first gauge and/or smaller than the second gauge. Advantageously, the first and second lateral and medial areas work in combination to provide support in the midfoot and/or quarter regions while also providing breathability.
