Abstract

An insert system for an article of footwear includes an outer assembly, a first insert assembly and a second insert assembly. The outer assembly is configured to interchangeably receive the first insert assembly and the second insert assembly. The first insert assembly includes a first sleeve member and a first midsole configured to provide enhanced cushioning and support. The first sleeve member includes a tongue and a fastening member that wraps around the tongue. The second insert assembly includes a second sleeve member and a second midsole configured to enhance speed. The second sleeve member is open at a forefoot portion and at a heel portion. The outer assembly includes an aperture on a sidewall of an outer sole portion, where the midsole inserted within the outer assembly is visible through the aperture.

First claim

What is claimed is:

1 . A kit of parts, comprising:
an outer assembly including an upper portion and an outer sole portion permanently attached to the upper portion, the outer assembly configured to separately receive at least two different removable midsoles; wherein the at least two different removable midsoles are configured to be interchangeable with the outer assembly to provide an article of footwear having different footwear characteristics associated with each of the at least two different removable midsoles, the at least two different removable midsoles comprising: a first removable midsole having a first color; a second removable midsole having a second color that is different from the first color; wherein the outer sole portion includes an outsole extending along the bottom of the outer sole portion and an outer sidewall portion; wherein the outer sole portion includes at least one aperture open on the sidewall portion of the outer sole portion and wherein the at least one aperture is spaced apart from the outsole of the outer sole portion; wherein the first color is visible through the at least one aperture when the first removable midsole is inserted within the outer assembly and wherein the second color is visible through the at least one aperture when the second removable midsole is inserted within the outer assembly; and wherein the first color being visible through the at least one aperture is configured to indicate a first set of footwear characteristics for the article of footwear; and wherein the second color being visible through the at least one aperture is configured to indicate a second set of footwear characteristics for the article of footwear.

2 . The kit of parts according to claim 1 , wherein the first removable midsole and the second removable midsole differ in at least one material characteristic.

3 . The kit of parts according to claim 2 , wherein the first removable midsole and the second removable midsole differ in rigidity.

4 . The kit of parts according to claim 2 , wherein the first removable midsole is comprised of a foam having a first density and the second removable midsole is comprised of a foam having a second density, and wherein the first density is different from the second density.

5 . The kit of parts according to claim 2 , wherein the first removable midsole includes an air bladder.

6 . The kit of parts according to claim 5 , wherein the second removable midsole is comprised of a substantially monolithic portion with an approximately constant density throughout the entirety of the second removable midsole.

7 . The kit of parts according to claim 1 , wherein the kit of parts further includes a first sleeve member, wherein the first sleeve member and the first removable midsole comprise a first removable insert assembly; and wherein the kit of parts includes a second sleeve member, wherein the second sleeve member and the second removable midsole comprise a second removable insert assembly.

8 . The kit of parts according to claim 1 , wherein the outer assembly, the first removable midsole, and the second removable midsole are packaged together within a container.

9 . The kit of parts according to claim 1 , wherein the at least one aperture open on the sidewall portion of the outer sole portion is disposed at a heel portion.

10 . A kit of parts, comprising:
an outer assembly including an upper portion and an outer sole portion; the upper portion including an opening and a fastening region, wherein the fastening region can be used to change the size of the opening; the outer assembly configured to separately receive at least two different removable insert assemblies, wherein the at least two different removable insert assemblies are configured to be interchangeable with the outer assembly to provide an article of footwear having different footwear characteristics associated with each of the at least two different removable insert assemblies, the at least two different removable insert assemblies comprising: a first insert assembly including a first sleeve member and a first midsole, the first midsole having a first color, wherein the first insert assembly can be removably inserted into the outer assembly; a second insert assembly including a second sleeve member and a second midsole, the second midsole having a second color different from the first color, wherein the second insert assembly can be removably inserted into the outer assembly, and wherein the second sleeve member is different from the first sleeve member; wherein the outer sole portion includes an outsole extending along the bottom of the outer sole portion and an outer sidewall portion; wherein the outer sole portion includes at least one aperture open on the sidewall portion of the outer sole portion and wherein the at least one aperture is spaced apart from the outsole of the outer sole portion; wherein the first color is visible through the at least one aperture when the first insert assembly is inserted within the outer assembly and wherein the second color is visible through the at least one aperture when the second insert assembly is inserted within the outer assembly; wherein the first insert assembly inserted within the outer assembly is configured to provide an article of footwear having a first set of footwear characteristics; and wherein the second insert assembly inserted within the outer assembly is configured to provide an article of footwear having a second set of footwear characteristics, the first set of footwear characteristics being different from the second set of footwear characteristics.

11 . The kit of parts according to claim 10 , wherein the first color being visible through the at least one aperture is configured to indicate the first set of footwear characteristics for the article of footwear; and
wherein the second color being visible through the at least one aperture is configured to indicate the second set of footwear characteristics for the article of footwear.
