14. The automatic lacing system according to claim 8, wherein the rigid hollow plate is disposed against an outer surface of the sidewall portion.

15. The automatic lacing system according to claim 8, wherein the rigid hollow plate is disposed between an outer lining of the sidewall portion and an inner lining of the sidewall portion.

16. The automatic lacing system according to claim 8, wherein the strap moving mechanism further comprises: a motor including a driveshaft; the driveshaft including a gear; a belt configured to engage the gear; and wherein the belt is configured to supply power to the at least one strap.

17. An automatic lacing system for an article of footwear, comprising: a first strap and a second strap configured to adjust an upper of an article of footwear, the first strap being disposed adjacent to the second strap; a strap moving mechanism connected to the first strap and the second strap, the strap moving mechanism being configured to automatically move the first strap and the second strap; and wherein the first strap and the second strap are configured to move substantially in unison when the strap moving mechanism is operated to automatically adjust the upper.

18. The automatic lacing system according to claim 17, wherein the spacing between adjacent portions of the first strap and the second strap is substantially constant.

19. The automatic lacing system according to claim 17, wherein the first strap and the second strap are attached to a yoke member that is configured to apply a force to the first strap and the second strap.

20. The automatic lacing system according to claim 17, wherein the first strap and the second strap are disposed beneath a lacing gap of the upper.

21. The automatic lacing system according to claim 17, wherein the first strap and the second strap oriented along a lateral direction of the upper.

22. An automatic lacing system for an article of footwear, comprising: a strap moving mechanism; a strap including a first end portion attached to the strap moving mechanism and a second end portion attached to a sidewall portion of an upper of the article of footwear; and wherein the strap moving mechanism is configured to move the first end portion from a first position to a second position and thereby loosen the upper.

23. The automatic lacing system according to claim 22, wherein the strap moving mechanism is in communication with a sensor.

24. The automatic lacing system according to claim 23, wherein the sensor is a weight sensor.

25. The automatic lacing system according to claim 23, wherein the strap moving mechanism is configured to move the strap according to information received from the sensor.

26. The automatic lacing system according to claim 22, wherein the strap moving mechanism is in communication with a user controlled device.

27. The automatic lacing system according to claim 26, wherein the strap moving mechanism is configured to move the strap according to information received from the user controlled device.

28. An automatic ankle cinching system for an article of footwear, comprising: an upper including an ankle portion; a housing disposed on a rear portion of the ankle portion; an ankle strap associated with a front portion of the ankle portion; a strap moving mechanism disposed within the housing; the strap including a first end portion attached to the strap moving mechanism and a second end portion fixedly attached to the housing; and wherein the strap moving mechanism is configured to automatically move the strap between an open position and a closed position and thereby adjust the ankle portion.

29. The automatic ankle cinching system according to claim 28, wherein the strap moving mechanism includes a coil spring.

30. The automatic ankle cinching system according to claim 29, wherein the coil spring provides tension to the first end portion.

31. The automatic ankle cinching system according to claim 30, wherein the coil spring applies tension to the first end portion in a direction to automatically close the ankle strap.
