1. A method for triggering an alert, comprising:
using a first physiological sensor to obtain a first measurement at a first physiological area on a user's foot;
using a second physiological sensor to obtain a second measurement at a second physiological area on the user's foot, wherein the first physiological sensor neighbors the second physiological sensor;
identifying a tissue shearing event at least by comparing the first measurement to the second measurement, increasing a shearing counter when a predetermined differential between the first measurement and the second measurement is detected, and comparing the shearing counter to a threshold; and
triggering an alert if the tissue shearing event is identified.
