an upper;
a sole structure;
a rechargeable power source positioned in the sole structure;
a tensioning system, operatively coupled to the rechargeable power source, configured to increase and decrease tension on a lace; and
a secondary wireless recharge antenna, positioned in the sole structure and operatively coupled to and co-located with the rechargeable power source;
wherein the secondary wireless recharge antenna is configured to have a current induced therein by a primary wireless recharge antenna of a charging component of a recharge system when the charging component is placed in proximity of the sole structure, the recharge system configured to be operatively coupled to an external power source;
wherein the rechargeable power source is configured to be recharged based on the current induced in the secondary wireless recharge antenna and provide the power to increase and decrease the tension on the lace.
2. The article of footwear of claim 1 , wherein the secondary wireless recharge antenna is an inductive loop.
3. The article of footwear of claim 2 , wherein the recharge system is configured to be placed in proximity of the sole structure.
4. The article of footwear of claim 3 , wherein the sole structure is configured to mechanically engage with the recharge system.
5. The article of footwear of claim 4 , wherein the recharge system is configured to mechanically engage with sole structures of articles of footwear having different sizes.
6. A method of making an article of footwear, comprising:
securing a sole structure to an upper;
positioning a rechargeable power source in the sole structure;
operatively coupling a tensioning system to the rechargeable power source, the tensioning system configured to increase and decrease tension on a lace; and
positioning a secondary wireless recharge antenna in the sole structure to co-locate the secondary wireless recharge antenna with the rechargeable power source; and
operatively coupling the secondary wireless recharge antenna to the rechargeable power source;
wherein the secondary wireless recharge antenna is configured to have a current induced therein by a primary wireless recharge antenna of a charging component of a recharge system when the charging component is placed in proximity of the sole structure, the recharge system configured to be operatively coupled to an external power source;
wherein the rechargeable power source is configured to be recharged based on the current induced in the secondary wireless recharge antenna and provide the power to increase and decrease the tension on the lace.
7. The method of claim 1 , wherein the secondary wireless recharge antenna is an inductive loop.
8. The method of claim 2 , wherein the recharge system is configured to be placed in proximity of the sole structure.
9. The method of claim 3 , wherein the sole structure is configured to mechanically engage with the recharge system.
10. The method of claim 4 , wherein the recharge system is configured to mechanically engage with sole structures of articles of footwear having different sizes.
11. A system, comprising:
an article of footwear comprising:
an upper;
a sole structure;
a rechargeable power source;
a secondary wireless recharge antenna, positioned in the sole structure and operatively coupled to and co-located with the rechargeable power source; and
a tensioning system, operatively coupled to the rechargeable power source, configured to increase and decrease tension on a lace engaged with the upper; and
a recharge system, configured to be operatively coupled to an external power source, comprising a charging component, the charging component configured to be in proximity of the article of footwear and comprising a primary wireless recharge antenna, the primary wireless recharge antenna configured to induce a current in the secondary wireless recharge antenna when energized by the external power source;
wherein the rechargeable power source is configured to be recharged based on the current induced in the secondary wireless recharge antenna and provide the power to increase and decrease the tension on the lace.
12. The system of claim 11 , wherein the primary and secondary wireless recharge antennas are inductive loops.
13. The system of claim 12 , wherein the recharge system is configured to be placed in proximity of the article of footwear.
14. The system of claim 13 , wherein the recharge system is configured to mechanically engage with the article of footwear.
15. The system of claim 14 , wherein the recharge system is configured to mechanically engage with articles of footwear having different sizes.
16. The system of claim 15 , wherein the recharge system comprises a first primary wireless recharge antenna and a second primary wireless recharge antenna, wherein the first primary wireless recharge antenna is configured to induce the current in the secondary wireless recharge antenna and wherein the second primary wireless recharge antenna is configured to induce a current in a different secondary wireless recharge antenna of a different article of footwear.
17. The system of claim 16 , wherein the first and second primary wireless recharge antennas are configured to be energized concurrently.
18. The system of claim 17 , wherein the rechargeable power source is a rechargeable battery.
19. The system of claim 18 , wherein the external power source is an AC power source.
20. The system of claim 18 , wherein the external power source is a DC power source.
