1. A method for analyzing gait and providing real time feedback on gait asymmetry to a user, comprising:
- a) receiving sensor data from a plurality of force sensors and at least one accelerometer disposed within left and right shoes when the shoes are moved through gait motions by a user of the shoes;
b) analyzing the sensor data with an electronic processor located remotely from the plurality of sensors, wherein analyzing the sensor data includes determining and comparing total stance phase forces, the electronic processor analyzing the sensor data by comparing sensor data from the left shoe to the right shoe to determine a difference between the left and right shoes, wherein determining a difference between the left and right shoes includes determining a difference between total stance phase forces; and
c) activating a sensory feedback alarm to alert the user when the difference between total stance phase forces or stance phase times of the left and right shoes exceeds a predetermined threshold.
