Abstract

Footwear articles are disclosed herein. Footwear articles may be formed using a method comprising disposing uncured resin adjacent a mold, disposing a lattice structure in at least a portion of the uncured resin disposed adjacent the mold, closing the mold using a lasted upper, and injecting foam into the closed mold such that the foam operates to couple the lasted upper and the lattice structure together.

Claims (33)

1 . A footwear article formed using a method comprising:

disposing uncured resin adjacent a mold;

disposing a lattice structure in at least a portion of the uncured resin disposed adjacent the mold;

closing the mold using a lasted upper; and

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

2 . The footwear article of claim 1 , wherein the lattice structure is formed using additive manufacturing.

3 . The footwear article of claim 1 , wherein the upper comprises a knit upper.

4 . The footwear article of claim 1 , wherein the closing the mold using a lasted upper comprises using a mold component comprising an integral upper.

5 . The footwear article of claim 1 , wherein the foam is injected into the mold via an aperture formed in the mold.

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

7 . The footwear article of claim 1 , wherein the first resin comprises a clear resin.

8 . The footwear article of claim 1 , wherein the lattice structure is formed using additive manufacturing.

9 . The footwear article of claim 1 , wherein the lattice structure is formed in the shape of the footwear article.

10 . The footwear article of claim 1 , wherein the lattice structure comprises one or more struts interconnected to define a plurality of apertures.

11 . A footwear article comprising:

A lasted upper;

a midsole; and

an outsole, wherein at least one of the midsole or the outsole are formed using a method comprising:

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;

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

releasing the mold.

12 . The footwear article of claim 11 , wherein one or more of the first resin or the second resin comprises a clear resin.

13 . The footwear article of claim 11 , wherein the foam is injected into the mold via an aperture formed in the female mold portion.

14 . The footwear article of claim 11 , wherein the foam operates as a base cushion layer in a footwear article.

15 . The footwear article of claim 11 , wherein the first resin is uncured.

16 . The footwear article of claim 15 , further comprising curing the first resin to provide a cured first resin in the female mold portion.

17 . The footwear article of claim 11 , wherein the male mold portion comprises a lasted upper.

18 . The footwear article of claim 11 , wherein the lasted upper is an integral upper.

19 . The footwear article of claim 11 , wherein rereleasing the mold comprises forming at least portion of at least one of the outsole or the midsole.

20 . The footwear article of claim 11 , wherein the lattice structure comprises one or more struts interconnected to define a plurality of apertures.
