Abstract

Methods for preparing a footwear article are disclosed herein. An example method may comprise disposing resin adjacent a mold, disposing a lattice structure in at least a portion of the resin disposed adjacent the mold, closing the mold using a lasted upper, injecting foam into the closed mold such that the foam operates to couple the lasted upper and the lattice structure together.

Claims (28)

1. A method for preparing a footwear article, the method comprising:

disposing an uncured first resin in a mold;

curing the first resin to provide a cured first resin;

disposing an uncured second resin on at least a portion of the cured first resin in the mold;

disposing a lattice structure in at least a portion of the uncured second resin disposed on the cured first resin in the mold;

closing the mold using a lasted upper;

injecting foam into the closed mold such that the foam operates to couple the lasted upper and the lattice structure together.

2. The method of claim 1 , wherein the first resin comprises a clear resin.

3. The method of claim 1 , wherein the lattice structure is formed using additive manufacturing.

4. The method of claim 1 , wherein the lasted upper comprise a knit upper.

5. The method of claim 1 , wherein the closing the mold using a lasted upper comprises using a mold component comprising an integral upper.

6. The method of claim 1 , wherein the foam operates as a base cushion layer in a footwear article.

disposing a first resin in a female mold portion of a mold associated with footwear;

closing the mold using a male mold portion;

disposing an uncured second resin on at least a portion of the first resin in the female mold portion;

disposing a lattice structure in at least a portion of the uncured second resin disposed on the first resin in the female mold portion;

reclosing the mold;

injecting foam into the mold such that the foam operates to couple the male mold portion and the lattice structure together; and

releasing the mold.

8. The method of claim 7 , wherein one or more of the first resin or the second resin comprises a clear resin.

9. The method of claim 7 , wherein the foam operates as a base cushion layer in a footwear article.

10. The method of claim 7 , wherein the first resin is uncured.

11. The method of claim 10 , further comprising curing the first resin to provide a cured first resin in the female mold portion.

12. The method of claim 7 , wherein the male mold portion comprises a lasted upper.

13. The method of claim 12 , wherein the lasted upper is an integral upper.

14. The method of claim 7 , wherein releasing the mold comprises forming at least a portion of a footwear article.

15. The method of claim 7 , wherein the lattice structure comprises one or more struts interconnected to define a plurality of apertures.
