Abstract

The disclosed method provides a way to manufacture a style of an article of footwear in bulk, while providing customization for heel stability for individual customers. Moreover, the disclosed method provides a way to customize articles of footwear for a customer on an ongoing basis, such that the heel stability of the articles of footwear is refined until a tailored fit is achieved for the same customer. Generally, the method may include providing a user/customer with an article of footwear, getting evaluation information about the stability of the article of footwear from a survey (e.g., asking the user to rate the stability of the article of footwear in a smartphone app), modifying the next article of footwear provided to the user/customer according to the evaluation information, and iterating through this process to give the user an article optimized for stability.

First claim

What is claimed is:

1. A method of customizing an article of footwear, comprising:
manufacturing a first article of footwear having a first sole structure with a forefoot region, a heel region opposite the forefoot region, and a midfoot region disposed between the forefoot region and the heel region, wherein the first article of footwear has a first heel stiffness profile;
providing the first article of footwear to a customer as part of a pair of shoes;
providing an evaluation system to the customer;
receiving and storing a customer evaluation of heel stability of the first article of footwear via the evaluation system;
receiving an order for a new pair of footwear from the customer;
in response to receipt of the order, retrieving the customer evaluation of heel stability that was received and stored;
in response to receipt of the order, manufacturing a second article of footwear having a second sole structure with a forefoot region, a heel region opposite the forefoot region, and a midfoot region disposed between the forefoot region and the heel region, wherein the step of manufacturing the second article of footwear includes adjusting at least one layer of the second sole structure of the second article of footwear to have a second heel stiffness profile that is different from the first heel stiffness profile, and wherein the second heel stiffness profile differs from the first heel stiffness profile based on the retrieved customer evaluation of heel stability; and
providing the second article of footwear to the customer.

2. The method of claim 1 , wherein the step of adjusting at least one layer of the second sole structure includes removing material from the second sole structure to form at least one aperture to provide the second heel stiffness profile.

3. The method of claim 2 , wherein the step of removing material from the second sole structure includes drilling the at least one aperture into a surface of the second sole structure.

4. The method of claim 2 , wherein the step of removing material from the second sole structure includes using a laser to drill the at least one aperture into a surface of the second sole structure.

5. The method of claim 2 , wherein the step of removing material from the second sole structure includes using a rotary tool to drill the at least one aperture into a surface of the second sole structure.

6. The method of claim 2 , wherein the at least one aperture is a blind hole.

7. The method of claim 1 , wherein the step of providing the evaluation system includes providing the evaluation system to the customer on a mobile computer device, and wherein the customer evaluation is entered into the evaluation system through the mobile computer device.

8. The method of claim 1 , wherein the at least one layer of the second sole structure that is adjusted in the adjusting step is a midsole layer made from a foam material.

9. A method of customizing an article of footwear, comprising:
manufacturing a first article of footwear having a first sole structure with a forefoot region, a heel region opposite the forefoot region, and a midfoot region disposed between the forefoot region and the heel region, wherein the first article of footwear has a first heel stiffness profile;
providing the first article of footwear to a customer;
providing an evaluation system to the customer;
receiving and storing a first customer evaluation of heel stability of the first article of footwear via the evaluation system;
receiving an order for a new pair of footwear from the customer;
in response to receipt of the order, retrieving the first customer evaluation of heel stability that was received and stored;
in response to receipt of the order, manufacturing a second article of footwear having a second sole structure with a forefoot region, a heel region opposite the forefoot region, and a midfoot region disposed between the forefoot region and the heel region, wherein the step of manufacturing the second article of footwear includes adjusting the second sole structure of the second article of footwear to have a second heel stiffness that is different from the first heel stiffness profile, and wherein the second heel stiffness profile differs from the first heel stiffness profile based on the retrieved first customer evaluation; and
providing the second article of footwear to the customer.

10. The method of claim 9 , wherein the step of adjusting the second sole structure includes removing material from the second sole structure to create at least one aperture to provide the second heel stiffness profile.

11. The method of claim 9 , wherein the evaluation system includes a rating of heel stability that is based on multiple options of ratings.

12. The method of claim 9 , further comprising:
receiving a second customer evaluation of heel stability of the second article of footwear;
manufacturing a third article of footwear having a third sole structure with a forefoot region, a heel region opposite the forefoot region, and a midfoot region disposed between the forefoot region and the heel region;
using the first and second customer evaluations of heel stability to determine a third heel stiffness profile for the third sole structure, wherein the third heel stiffness profile is different from the first heel stiffness profile and the second heel stiffness profile;
adjusting the third sole structure of the third article of footwear to have the third heel stiffness profile; and
providing the third article of footwear to the customer.

13. The method of claim 10 , wherein the step of removing material from the second sole structure includes removing material from a lateral side of the heel region of the second sole structure.

14. The method of claim 10 , wherein the step of removing material from the second sole structure includes removing material from a lateral side of the heel region of the second sole structure to create at least one blind hole.

15. The method of claim 9 , wherein the step of providing the evaluation system includes providing the evaluation system to the customer on a mobile computer device, and wherein the customer evaluation is entered into the evaluation system through the mobile computer device.

16. A method of customizing an article of footwear, comprising:
manufacturing a first article of footwear having a first sole structure with a forefoot region, a heel region opposite the forefoot region, and a midfoot region disposed between the forefoot region and the heel region, wherein the first article of footwear has a first heel stiffness profile;
providing the first article of footwear to a customer;
providing an evaluation system to the customer;
receiving and storing a customer evaluation of heel stability of the first article of footwear via the evaluation system;
receiving an order for a new pair of footwear from the customer;
in response to receipt of the order, retrieving the customer evaluation of heel stability that was received and stored;
in response to receipt of the order, manufacturing a second article of footwear having a second sole structure with a forefoot region, a heel region opposite the forefoot region, a midfoot region disposed between the forefoot region and the heel region, wherein the second sole structure has an outer surface with an upper surface, a lower surface, and a sidewall, wherein the step of manufacturing the second article of footwear includes removing material from the outer surface of the second sole structure of the second article of footwear to produce a second heel stiffness profile in the second article of fo
