Abstract
A shoe has an activity level meter that displays, in a highly noticeable fashion, such as by lighting bright LEDs, the highest level of activity reached by a wearer of the shoe. In one embodiment, the display is a three-element LED display in which zero to three LEDs flash briefly, but brightly each time the weight of the wearer is fully pressed against the inner sole of the shoe during a period of activity. A period of time after the activity ends, the LEDs light again for a longer period of time to indicate the highest level of activity reached during the activity period.
