  • an article of footwear that has an upper with a pivoting tongue that enables easy foot entry, and one or more anchoring straps configured to be easily movable and securable over the tongue for use.
  • the footwear may be implemented for all sizes, and is especially useful for young children as it may enable them to independently don and doff their footwear.
  • an article of footwear includes a footwear upper that has a base layer, a tongue, and a strap.
  • the base layer defines a throat opening
  • the tongue has a forward end fixed to the base layer forward of the throat opening.
  • the tongue is pivotable about the forward end between an access position and a use position.
  • the tongue may be configured to easily reflect (e.g., fold or bend) about the forward end to uncover most or all of the throat opening in the access position. A larger entry area is thus available for foot entry when the tongue is in the access position.
  • the tongue extends over and covers the throat opening in the use position, and rests against the exterior of the base layer at a medial side of the base layer and at a lateral side of the base layer. Stated differently, the tongue covers over the top side of the throat opening and overlaps the base layer on either side of the throat opening.
  • the strap has an anchored end fixed at the base layer (e.g., fixed relative to the base layer, including indirectly fixed to the base layer).
  • the strap has a securing end selectively securable at the base layer (e.g., selectively securable relative to the base layer, including indirectly securable to the base layer).
  • the strap crosses over an exterior of the tongue with the securing end secured at the base layer and the tongue in the use position. The strap thus holds the tongue in place over the foot during use.
  • the strap may be configured to be easily securable and releasable.
  • a first fastener such as a hook-and-loop fastener may be fixed at the securing end of the strap
  • a second fastener may be fixed at a side of the upper opposite from the side at which the anchored end of the strap is fixed.
  • the strap may thus be secured simply by pressing the first fastener against the second fastener, and released by pulling the securing end of the strap away from the second fastener to release the first fastener from the second fastener.
  • a single strap is selectively securable over the tongue.
  • Other examples include a first strap and a second strap, e.g., a medial strap and a lateral strap, that cross over the tongue to opposite sides of the upper, with one of the straps crossing over the other strap.
  • Other features of the article of footwear may include a tongue pull, a heel pull, binding or reinforcing skin that helps stiffen the perimeter of the upper around the throat opening to maintain the opening shape for easy entry, and that provides structure at the side and rear edges of the tongue.
  • Foam cushioning on the underside of the tongue and at a heel collar of the upper may also be used to provide structure to maintain the opening size and tongue shape, as well as to increase comfort.
  • FIG. 1 shows an article of footwear 10 that includes an upper 12 with a pivotable tongue 14 and two straps 16A, 16B (also referred to as anchoring straps) that are configured to enable easy donning and doffing of the footwear 10 as described herein.
  • straps 16A, 16B also referred to as anchoring straps
  • FIG. 1 is a lateral side view of the article of footwear 10 showing the upper 12 secured to a sole structure 18 to together define a foot-receiving cavity 20 in which a foot is disposed when the footwear 10 is worn.

  • FIG. 1 shows a lateral side 28 of the article of footwear 10
  • FIG. 2 shows an opposite medial side 30 of the article of footwear 10.
  • the lateral side 28 and the medial side 30 are used herein to describe portions of both the sole structure 18 and portions of the upper 12.
  • the lateral side 28 and the medial side 30 extend through each of forefoot region 22, the midfoot region 24, and the heel region 26 and correspond with opposite sides of the article of footwear 10 divided by a longitudinal axis LM (indicated in FIG. 3), which may be a longitudinal midline of the article of footwear 10.
  • the forefoot region 22, the midfoot region 24, and the heel region 26 are not intended to demarcate precise areas of footwear 10, but are instead intended to represent general areas of the article of footwear 10 to aid in the discussion.
  • the article of footwear 10 is for a right foot.
  • a pair of footwear includes the article of footwear 10, and an article of footwear for a left foot that is a mirror image of the article of footwear 10. Accordingly, the description of the footwear 10 applies equally to a right foot article of footwear and a left foot article of footwear, both of which are within the scope of the present teachings.
  • the sole structure 18 may include any or all of an outsole, a midsole, and one or more fluid-filled or foam cushioning elements.

  • the base layer 32 is spread into a relatively flat position, and the securement of the tongue 14 to the base layer 32 occurs prior to securing the lower extent of the base layer 32 to the sole structure 18.
  • rear edges 98, 100 of the base layer 32 are positioned adjacent one another at the heel region 26.
  • the cover skin 94 is first placed over the first series of stitches 92 and then stitched to the base layer 32 with the second series of stitches 96.
  • the tongue 14 is configured to be relatively thin and flexible at its forward end 80 by having only an outer layer 90 (and, optionally, the thin inner layer 109) at the forward end 80, the tongue 14 has features configured to reinforce the remaining edges of the outer layer 90 (e.g., the remaining perimeter other than the forward end 80, including the edges 84, 86) so that the tongue 14 will tend to remain relatively spread out or fanned out as opposed to folding or wrinkling at the perimeter of the tongue 14. This enables the tongue 14 to reliably extend outward of the medial and lateral edges 34B, 34C of the throat opening 34 when secured during use as discussed.
  • the outer layer 90 may be, for example, the same material as the base layer 32, such as a textile.

  • the edges 84, 86, and end 104 of the outer layer 90 are indicated as coincident with the edges of the tongue edge binding 102 as the tongue edge binding 102 may be relatively thin and is wrapped tightly around the edges of the outer layer 90.
  • the tongue edge binding 102 may be nylon, polyester, leather, etc. As shown in FIG. 8, there may be a small gap between the edges 84, 86 and the tongue edge binding 102.
  • Stitching 108 extends through the tongue edge binding 102 and the outer layer 90 to secure the tongue edge binding 102 to the outer layer 90, as best shown in FIG. 8.
  • the stitching 108 also extends through an inner layer 109 of the tongue 14, and is shown as having a zig-zag pattern (see FIG. 1).
  • the tongue edge binding 102 is thus also wrapped around the outer edge of the inner layer 109.
  • the inner layer 109 may be thinner than the outer layer 90, and may be, but is not limited to, a nylon liner.
  • the tongue edge binding 102 does not extend to the forward end 80.
  • the tongue edge binding 102 has a medial terminal end 102A rearward of the forward end 80, and a lateral terminal end 102B rearward of the forward end 80.

  • the lateral edge 86 of the outer layer 90 has an unbinded portion 86A exposed between the lateral terminal end 102B of the tongue edge binding 102 and the forward end 80 of the tongue 14.
  • the unbinded portions 84A, 86A may still be exposed, as best shown in FIG. 12.
  • the tongue 14 may tend to bend or fold at these unbinded portions 84A, 86A when pivoting near the forward end 80 rather than more rearward where the edges 84, 86 are covered by the binding 102 and where, therefore, the tongue 14 is thicker.
  • the portions 84A, 86A of the edges 84, 86 remain a relatively thin portion of the edges 84, 86, as only the outer layer 90 and inner layer 109 and not the binding 102 extend at these portions of the edges 84, 86.
  • the tongue edge binding 102 thus helps to control the location of pivoting of the tongue to near the forward end 80, which results in the greatest exposure of the throat opening 34 for access when donning the footwear 10.
  • edge binding 110 may also be secured to the base layer 32 along a perimeter of the throat opening 34 at a medial edge 34B of the throat opening and at a lateral edge 34C of the throat opening 34.
  • the edge binding 110 may be nylon, polyester, leather, etc.
  • the edge binding 110 further extends along and is secured to the collar 38 at a perimeter of the ankle opening 40. It is noted that in the plan views herein, the cushioning of the collar 38 bulges inward below the top of the ankle opening 40.
  • the edge binding 110 terminates rearward of the forwardmost end 34A of the throat opening 34 such that the forwardmost end 34A and forward portions of the medial and lateral edges 34B, 34C of the throat opening 34 are free from any edge binding 110.
  • the edge binding 110 has a medial terminal end 110A disposed along the medial edge 34B rearward of the forwardmost end 34A, and a lateral terminal end 110B disposed along the lateral edge 34C rearward of the forwardmost end 34A. Accordingly, the medial edge 34B has an unbinded portion 112A exposed between the medial terminal end 110A of the edge binding 110 and the forwardmost end 34A.
  • the lateral edge 34C has an unbinded portion 112B exposed between the lateral terminal end 110B of the edge binding 110 and the forwardmost end 34A. Because the throat opening 34 is rounded at the intersection of the medial edge 34B with the forwardmost end 34A and at the intersection of the lateral edge 34C with the forwardmost end 34A, some bending or folding may occur at the unbinded portions 112A, 112B during pivoting of the tongue 14. Leaving these portions 112A, 112B unbinded reduces their thickness in comparison to the portions of the edges 34B, 34C with binding 110, allowing more flexibility to reduce resistance to pivoting of the tongue 14 from the use position to the access position, and from the access position to the use position.
  • FIGS. 8-9 show the construction of the tongue 14.
  • the outer layer 90 of the tongue 14 includes a medial side portion 90A and a lateral side portion 90B.

  • the medial side portion 90 A and the lateral side portion 90B may be mirror images of one another.
  • Webbing 120 is disposed over and along the seam 119 and stitched to the medial side portion 90A and the lateral side portion 90B with stitching 122. The webbing 120 is thus secured along a central portion 115 of the outer layer 90 between the forward end 80 of the tongue 14 and a rear end 104 of the tongue 14, but does not extend completely to the rear end 104.
  • the stitching 122 ends partway between the rear end 104 and the forward end 80, and the webbing 120 is doubled over to create a loop portion serving as the tongue pull 120A and is secured to itself (and to the underlying outer layer 90 and inner layer 109) by a box stitch 120B disposed at and defining an anchor location 120C.
  • the outer layer 90 includes the forward end 80 of the tongue 14.
  • Foam 131 is disposed at an inner side 132 of the outer layer 90 as shown in FIG. 8.
  • the foam 131 is divided into a medial foam component 131 A at the medial side 30 of the tongue 14, and a lateral foam component 13 IB at the lateral side 28 of the tongue 14.
  • the medial foam component 131A and the lateral foam component 13 IB are separated from one another by a gap 134 extending along a length of the inner side 132 of the outer layer 90.
  • the relatively thin and flexible, inner layer 109 is able to extend into the gap 134 and be stitched to the outer layer 90 with the stitching 118 in the gap 134.
  • the foam 131 is positioned over the throat opening 34.
  • Providing the gap 134 allows greater flexibility of the foam 131 to provide a more customized fit to the top of the foot as the two foam components 131 A, 13 IB can be moved closer together (e.g., closing the gap 134) as the tongue 14 conforms to the top of the foot and to the exterior of the base layer 32 and is held in position by the straps 16A, 16B.
  • a forwardmost-edge 130C of the foam 131 is rearward of the forward end 80 of the tongue 14.
  • the outer layer 90 and inner layer 109 extend forward further than the foam 131 to ensure flexibility at the forward end 80.
  • Stitching 136 may secure the outer layer 90 and the inner layer 109 forward of the stitching 108 of the tongue edge binding 102.
  • the webbing 120 forms the tongue pull 120 A extending in a loop from the anchor location 120C that is disposed between the rear end 104 of the tongue and the forward end 80 of the tongue 14 along the central portion 115.
  • the stitching 122 secures a lower portion of the webbing 120 to the outer layer 90 and inner layer 109, and the box stitch 120B is added well below the rear end 104 so that that portion of the webbing 120 forming the tongue pull 120A is not secured to the outer layer 90 rearward of the anchor location 120C.
  • the straps 16A, 16B will generally be disposed over the anchor location 120C and act to maintain part of the tongue pull 120 A flattened under the straps 16A, 16B when the tongue 14 is in the use position and the straps 16A, 16B are secured, making it more difficult to access the tongue pull 120A until the straps 16A, 16B are released.
  • webbing 130 is secured to the heel foxing 36 and to the heel collar 38 at a rear of the heel region 26.
  • the webbing 130 is doubled over and stitched or otherwise secured to itself to define a heel pull 130A secured to the collar 38 rearward of the ankle opening 40.
  • the heel pull 130A may be used to pull the footwear 10 onto the foot when inserting the foot into the foot-receiving cavity 20, and may also be used to pull the footwear off of the foot when the straps 16A, 16B are unsecured and the tongue 14 is in the access position.

It will be understood that each of these directional adjectives may be applied to individual components of a sole.
  • the term “upward” or “upwards” particularly refers to the vertical direction pointing towards a top of the component, which may include an instep, a fastening region and/or a throat of an upper.
  • the term “downward” or “downwards” particularly refers to the vertical direction pointing opposite the upwards direction, toward the bottom of a component and may generally point towards the bottom of a sole structure of an article of footwear.
  • the “interior” of an article of footwear particularly refers to portions at the space that is occupied by a wearer’s foot when the shoe is worn.
  • the “inner side” of a component particularly refers to the side or surface of the component that is (or will be) oriented toward the interior of the component or article of footwear in an assembled article of footwear.
  • the “outer side” or “exterior” of a component particularly refers to the side or surface of the component that is (or will be) oriented away from the interior of the shoe in an assembled shoe. In some cases, other components may be between the inner side of a component and the interior in the assembled article of footwear.
  • other components may be between an outer side of a component and the space external to the assembled article of footwear.
  • the terms “inward” and “inwardly” particularly refer to the direction toward the interior of the component or article of footwear, such as a shoe
  • the terms “outward” and “outwardly” particularly refer to the direction toward the exterior of the component or article of footwear, such as the shoe.
  • proximal particularly refers to a direction that is nearer a center of a footwear component, or is closer toward a foot when the foot is inserted in the article of footwear as it is worn by a user.
  • distal particularly refers to a relative position that is further away from a center of the footwear component or is further from a foot when the foot is inserted in the article of footwear as it is worn by a user.
