| abstract |
Foot-receiving devices, such as articles of footwear (100), include: (a) a sensing device (102) that senses a characteristic of an interaction between a user's foot and a foot-receiving device; (b) a control system (104) that receives output from the sensing device and controls a characteristic of the foot-receiving device based on this output; and (c) a monitoring system for detecting and/or storing data indicating speed or distance information associated with use of the foot-receiving device. The monitoring system may receive input from the same sensing device used for providing data to the control system. The control system may alter the impact attenuation characteristics, the traction characteristics, the flexibility characteristics, the fit characteristics, or the like of the article of footwear. Methods of making and using such foot-receiving devices also are described. |
