Abstract

An article of footwear with a sole and an upper. The upper includes an inner layer configured to receive a foot and an outer layer with a first portion more stretchable than a second portion. A strobel board is disposed above the sole and attached to the inner layer. An inflatable bladder is disposed between the inner layer and the outer layer and attached to both a medial side and a lateral side of the strobel board. The inflatable bladder extends across a throat region of the upper and is operatively coupled with an inflation mechanism and release mechanism configured to inflate and deflate the inflatable bladder. A saddle is disposed between the inflatable bladder and the outer layer in lateral and medial quarter regions of the upper, but not extending into the throat region. The first portion of the outer layer covers the inflatable bladder at the throat region.

First claim

What is claimed is:

1 . An article of footwear comprising:
an upper comprising an inner layer configured to receive a foot and an outer layer having a first portion more stretchable than a second portion; a sole attached to the upper; a strobel board disposed above the sole and attached to the inner layer; an inflatable bladder disposed between the inner layer and the outer layer, attached to both a medial side and a lateral side of the strobel board, and extending across a throat region of the upper; an inflation mechanism and a release mechanism operatively coupled with the inflatable bladder and configured to inflate and deflate the inflatable bladder; and a saddle disposed between the inflatable bladder and the outer layer in lateral and medial quarter regions of the upper and not extending into the throat region, wherein the first portion of the outer layer covers the inflatable bladder at the throat region.

2 . The article of footwear of claim 1 , wherein the saddle is integral with the strobel board.

3 . The article of footwear of claim 1 , wherein the inner layer comprises a bootie.

4 . The article of footwear of claim 1 , wherein the inner layer comprises Lycra®.

5 . The article of footwear of claim 1 , wherein the inflatable bladder comprises a release agent cured to a first film by the application of ultraviolet light.

6 . The article of footwear of claim 5 , wherein the release agent is silicone fortified.

7 . The article of footwear of claim 5 , wherein the release agent is one of a paint, ink, paper, textile, particulate, photosensitive agent, TEFLON®, silicone, plastic, and acid.

8 . The article of footwear of claim 1 , wherein the inflatable bladder comprises:
a first film; a release agent applied and cured to said first film in a pattern that corresponds to the shape of an inflatable compartment of said inflatable bladder; and a second film adhered to said first film such that said release agent is disposed between said first film and said second film, and said first film and said second film do not adhere in the vicinity of the release agent thereby forming said inflatable compartment with a peripheral edge.

9 . The article of footwear of claim 1 , wherein the saddle comprises a plurality of loops configured to extend through slots in the outer layer and receive a shoelace.

10 . The article of footwear of claim 9 , wherein the plurality of loops comprises a single continuous cord.

11 . The article of footwear of claim 10 , wherein the saddle further comprises a lace piece over a portion of the continuous cord.

12 . The article of footwear of claim 1 , wherein the outer layer comprises a screen printing on an outer surface.

13 . The article of footwear of claim 1 , wherein the throat region is tongueless.

14 . The article of footwear of claim 1 , wherein the saddle is configured to limit outward bulging of the inflatable bladder.

15 . The article of footwear of claim 1 , wherein the saddle is configured to limit bulging of the inflatable bladder in one of a lateral and a medial direction.

16 . The article of footwear of claim 1 , wherein the inflatable bladder is attached to the outer layer in the throat region.

17 . The article of footwear of claim 1 , wherein the inflatable bladder is attached to the outer layer and the inner layer in the throat region.

18 . An upper for an athletic shoe comprising:
an inner layer configured to attach to an insole of the athletic shoe and receive a foot; an outer layer having a first portion more stretchable than a second portion; an inflatable bladder disposed between the inner layer and the outer layer and extending from a lower lateral side of the upper across a throat region of the upper to a lower medial side of the upper; an inflation mechanism and a release mechanism operatively coupled with the inflatable bladder and configured to inflate and deflate the inflatable bladder; a lateral saddle disposed between the inflatable bladder and the outer layer in a lateral quarter region of the upper and not extending into the throat region; and a medial saddle disposed between the inflatable bladder and the outer layer in a medial quarter region of the upper and not extending into the throat region, wherein the throat region of the upper is tongueless and aligns with an edge of each of the lateral and medial saddles, and wherein the first, portion of the outer layer is disposed in the throat region.

19 . The upper of claim 18 , wherein the inner layer comprises a bootie.

20 . The upper of claim 18 , wherein the inner layer comprises Lycra®.

21 . The upper of claim 18 , wherein the inflatable bladder comprises a release agent cured to a first film by the application of ultraviolet light.

22 . The upper of claim 21 , wherein the release agent is silicone fortified.

23 . The upper of claim 21 , wherein the release agent is one of a paint, ink, paper, textile, particulate, photosensitive agent, TEFLON®, silicone, plastic, and acid.

24 . The upper of claim 18 , wherein the inflatable bladder comprises:
a first film; a release agent applied and cured to said first film in a pattern that corresponds to the shape of an inflatable compartment of said inflatable bladder; and a second film adhered to said first film such that said release agent is disposed between said first film and said second film, and said first film and said second film do not adhere in the vicinity of the release agent thereby forming said inflatable compartment with a peripheral edge.

25 . The upper of claim 18 , wherein each of the lateral and medial saddles comprises a plurality of loops configured to extend through slots in the outer layer and receive a shoelace.

26 . The upper of claim 25 , wherein each of the plurality of loops on the lateral saddle and the plurality of loops on the medial saddle comprises a single continuous cord.

27 . The upper of claim 26 , wherein each of the lateral and medial saddles further comprises a lace piece over a portion of the continuous cord.

28 . The upper of claim 18 , wherein the outer layer comprises a screen printing on an outer surface.

29 . The upper of claim 18 , wherein each of the lateral and medial saddles is configured to limit outward bulging of the inflatable bladder.

30 . The upper of claim 18 , wherein each of the lateral and medial saddles is configured to limit bulging of the inflatable bladder in one of a lateral and a medial direction.
