6. An article of footwear according to claim 4 , wherein the electronic module is a speed and distance sensor.

7. An article of footwear according to claim 1 , wherein the housing is located in an impact-attenuating element of the article of footwear such that the electronic module receiving chamber faces the foot-receiving chamber.

8. An article of footwear according to claim 7 , wherein the impact-attenuating element includes an opening defined therein that allows the aglet access to the activation system.

9. An article of footwear according to claim 7 , further comprising:

an insole member or a sock liner at least partially defining the foot-receiving chamber.

10. An article of footwear according to claim 9 , wherein the insole member or sock liner includes an opening defined therein that allows the aglet access to the activation system.

11. An article of footwear according to claim 10 , wherein the impact-attenuating element includes an opening defined therein that at least partially aligns with the opening defined in the insole member or sock liner to allow the aglet access to the activation system.

12. An article of footwear according to claim 1 , further comprising:

an antenna system engaged with at least one of the upper member or the sole structure.

13. An article of footwear according to claim 12 , wherein the antenna system extends from the chamber.

14. An article of footwear according to claim 12 , further comprising:

the electronic module, wherein the electronic module is engaged at least partially within the chamber and operatively coupled with the antenna system.

15. An article of footwear according to claim 1 , further comprising:

a power source engaged with at least one of the upper member or the sole structure.

16. An article of footwear according to claim 15 , wherein the power source includes an electrical contact or terminal located at or engaged with the housing.

17. An article of footwear according to claim 15 , further comprising:

the electronic module engaged at least partially within the housing and in electrical communication with the power source.

18. An article of footwear, comprising:

an upper member at least partially defining a foot-receiving chamber;

a sole structure engaged with the upper member;

a housing for receiving an electronic module, the housing engaged with at least one of the upper member or the sole structure, wherein the housing defines an electronic module receiving chamber; and

an authentication system for receiving input information and confirming authorization for use of an electronic module in the chamber based, at least in part, on the input information,

wherein the authentication system includes an activation tool, the activation tool configured to provide the input information for authorizing use of the electronic module.

19. An article of footwear according to claim 18 , further comprising:

an electronic module received in the electronic module receiving chamber.

20. An article of footwear according to claim 19 , wherein the authentication system includes a member extending from a wall of the housing for extending into an opening, recess, or groove defined in the electronic module.

21. An article of footwear according to claim 20 , wherein the member extends into the opening, recess, or groove to allow activation of the electronic module.

22. An article of footwear according to claim 20 , wherein the member includes a first electrical conductor that makes electrical contact with a second electrical conductor provided in the opening, recess, or groove.

23. An article of footwear according to claim 19 , wherein the authentication system includes a member extending from the electronic module for extending into an opening, recess, or groove defined in the housing or sole structure.

24. An article of footwear according to claim 23 , wherein the member extends into the opening, recess, or groove to allow activation of the electronic module.

25. An article of footwear according to claim 23 , wherein the member includes a first electrical conductor that makes electrical contact with a second electrical conductor provided in the opening, recess, or groove.

26. An article of footwear according to claim 19 , wherein the electronic module provides data relating to at least one physical or physiological parameter associated with use of the article of footwear.
