Abstract

An article of footwear incorporates a textile upper. The upper comprises a knitted component. The knitted component may be warp knitted. The knitted component has an outer side and an inner side that can have different knit configurations. The knitted component can also incorporate portions of a single layer construction and portions of a double layer construction. The double layer construction forms pockets on portions of the knitted component. Inserts can be placed into the pockets to provide support, stability, or other desired properties to the portions of the knitted component.

First claim

What is claimed is:

1. A method of making an upper for an article of footwear, comprising:
knitting a knitted textile element of unitary knit construction comprising:
a first portion comprising a single layer of material;
a second portion comprising a plurality of areas having two distinct layers of material that are separated to form a plurality of pockets;
a first indicating portion corresponding to the outline of a knitted component; and
a second indicating portion corresponding to one of the plurality of pockets in the knitted component;

cutting the knitted textile element along the first indicating portion to separate the knitted component from excess material of the knitted textile element;
cutting the knitted component along the second indicating portion to create an opening to the one of the plurality of pockets;
inserting an insert member into the one of the plurality of pockets and closing the one of the plurality of pockets; and joining edges of the knitted component to form the upper.

2. The method according to claim 1 , wherein the insert member comprises a cushioning member.

3. The method according to claim 2 , wherein the cushioning member is made of a foam material.

4. The method according to claim 1 , wherein the method includes associating a sole structure with the upper.

5. The method according to claim 1 , wherein the insert member comprises a rigid material.

6. The method according to claim 1 , further comprising:
heating at least a portion of the knitted component including the one of the plurality of pockets having the insert member disposed within.

7. The method according to claim 6 , wherein the heating step fixes the insert member within the one of the plurality of pockets.

8. A method of knitting a knitted component for use as an upper in an article of footwear, comprising
knitting a first portion of the knitted component so that the first portion comprises a single layer construction;
knitting a second portion of the knitted component so that the second portion comprises a plurality of areas of the knitted component having a double layer construction that are separated to form a plurality of pockets;
knitting a knitted indicating portion configured to indicate a location for cutting a layer of the second portion to provide access to one of the plurality of pockets; and
wherein the first portion, the second portion and the knitted indicating portion are formed of unitary knit construction.

9. The method according to claim 8 , wherein knitting the first portion comprises knitting a first side of the first portion to have a first knit configuration and knitting a second side of the first portion to have a second knit configuration that is different from the first knit configuration.

10. The method according to claim 8 , wherein knitting the second portion comprises knitting the double layer construction such that a first layer of the double layer construction has a first knit configuration and a second layer of the double layer construction has a second knit configuration that is different from the first knit configuration.

11. The method according to claim 8 , wherein knitting comprises warp knitting the knitted textile element.

12. The method according to claim 8 , wherein the knitted indicating portion comprises perforations.

13. The method according to claim 8 , wherein the knitted indicating portion is associated with a portion of the second portion that is adjacent to the first portion.

14. The method according to claim 8 , wherein the knitted indicating portion is visible only on one side of the textile element.

15. A method of knitting a knitted component for an article of footwear, the method comprising:
knitting a first portion of the knitted component so that the first portion comprises a single layer construction;
knitting a second portion of the knitted component so that the second portion comprises a plurality of areas of the knitted component having a double layer construction that are separated to form a plurality of pockets; and
wherein the first portion and the second portion are formed of unitary knit construction.

16. The method according to claim 15 , wherein an outer side of the first portion is formed of unitary knit construction with a first layer of the second portion and wherein an inner side of the first portion is formed of unitary knit construction with a second layer of the second portion.

17. The method according to claim 15 , wherein the step of knitting the plurality of areas of the knitted component with the double layer construction further comprises locating the plurality of pockets at least on two different portions of the knitted component.

18. The method according to claim 15 , further comprising removing the knitted component including the first portion and the second portion from a knitted textile element.
