Extruded components for articles of footwear and methods of making the same
Extruded components for articles of footwear and methods of making such articles of footwear are disclosed. A carrier can be formed from a first material, the carrier including an attachment surface configured to attach to an upper and a receiving surface having a plurality of receptacles. A second material can be extruded into a plurality of the receptacles to form cushioning elements of a sole.
1. A method of making a sole for an article of footwear, the method comprising:
extruding a continuous elongate winding onto a substrate, wherein the winding comprises a first material and defines a plurality of receptacles devoid of the first material; and
extruding a second material into a plurality of the receptacles, wherein the second material forms a separate cushioning element of the sole in each of the plurality of the receptacles,
wherein the winding and the second material define at least a portion of the sole.
2. The method of claim 1 , wherein the winding comprises multiple layers in at least a heel portion of the sole.
3. The method of claim 1 , wherein the first and second materials are non-ink, thixotropic materials.
4. The method of claim 1 , wherein the first and second materials comprise a polyester-based urethane or polyether-based urethane.
5. The method of claim 1 , wherein the substrate comprises a fabric.
6. The method of claim 1 , wherein the winding is disposed in a groove on the substrate.
7. A method of making an article of footwear, the method comprising:
disposing a carrier onto a substrate, the carrier defining a shape of a sole portion of the article of footwear, wherein the carrier comprises receptacles; and
extruding a thixotropic material into a plurality of the receptacles, wherein the thixotropic material forms a separate cushioning element of the sole portion in each of the plurality of the receptacles,
wherein the carrier comprises one or more windings forming a frame.
8. The method of claim 7 , wherein disposing the carrier onto the substrate comprises extruding a winding onto a non-stick surface.
9. The method of claim 7 , wherein the windings are a different material than the cushioning elements.
10. The method of claim 7 , wherein the windings are the same material as the cushioning elements.
11. The method of claim 7 , wherein the windings comprise more than one layer.
12. The method of claim 7 , further comprising extruding medial and lateral wings coupled to the frame.
13. The method of claim 12 , further comprising folding the medial and lateral wings toward each other to form a portion of an upper.
14. The method of claim 12 , further comprising coupling a plurality of lace attachments to the medial and lateral wings.
