First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing an article of footwear, the method comprising: positioning an upper on a last, the last defining openings connected by one or more channels in the last; injecting a material through the one or more channels in the last; and forming a structure on the upper with the material, wherein the structure comprises upper padding. 2. The method of claim 1 , wherein the structure comprises a midsole. 3. The method of claim 1 , wherein the openings comprise an inlet at a top of the last and an outlet at a bottom of the last. 4. The method of claim 1 , further comprising customizing the structure based on data associated with a wearer. 5. The method of claim 1 , wherein the last defines a cavity at a bottom portion of the last. 6. The method of claim 5 , wherein the cavity extends most of the length of the last and most of the width of the last. 7. The method of claim 6 , wherein forming the structure on the upper comprises forming an insole in the cavity. 8. The method of claim 1 , wherein the last comprises a pattern with at least one of engraved features and embossed features. 9. A method of manufacturing an article of footwear, the method comprising: positioning an upper on a last; injecting a material through the last; and forming upper padding and a midsole with the material in a single, continuous process. 10. The method of claim 9 , further comprising injecting a second material through the last. 11. The method of claim 9 , further comprising using a modular attachment to shape the upper padding. 12. The method of claim 9 , further comprising obtaining foot data associated with a wearer. 13. The method of claim 12 , further comprising using the foot data associated with the wearer to customize the midsole and the upper padding. 14. A method of manufacturing an article of footwear, the method comprising: positioning an upper on a last, the last defining openings connected by one or more channels in the last; injecting a material through the one or more channels in the last; and forming a structure on the upper with the material, wherein the last comprises a pattern with at least one of engraved features and embossed features. 15. The method of claim 14 , wherein the structure comprises upper padding. 16. The method of claim 14 , wherein the structure comprises a midsole. 17. The method of claim 14 , wherein the openings comprise an inlet at a top of the last and an outlet at a bottom of the last. 18. The method of claim 14 , wherein the pattern comprises engraved features and embossed features. 19. The method of claim 14 , further comprising obtaining foot data associated with a wearer. 20. The method of claim 19 , further comprising using the foot data associated with the wearer to customize the structure.
