Claim 0:
1. A system for use in footwear, the system comprising:
a first sensor coupled to an article of footwear and configured to provide a capacitance-indicating sensor signal, wherein changes in the capacitance-indicating sensor signal correspond to changes in proximity of a foot to the first sensor; and
a processor circuit coupled to the first sensor, the processor circuit configured to:
detect a donning event using the sensor signal, the donning event corresponding to a change in the capacitance-indicating sensor signal from a first reference value to a second reference value, wherein the first reference value corresponds to the article of footwear being unoccupied by the foot and the second reference value corresponds to the article of footwear being occupied by the foot;
following the donning event, detect fluctuations in the sensor signal, wherein the fluctuations include respective changes in magnitude of the sensor signal by an intermediate magnitude amount, wherein the intermediate magnitude amount is at least a specified threshold magnitude change amount and is less than a magnitude difference between the first and second reference values; and

based on the fluctuations as detected, determine a step count or a step interval.
