Trackage provides an easy way to catalog workouts while reminding users when it is time to replace workout shoes. After setting desired shoe mileage users can access a countdown. When a pair of shoes hits “0 miles left” it is time to get a new pair of shoes. Users can also see the daily wear and tear on shoe soles by cataloging photos of shoes soles. Workouts and photos are easily accessible through calendar where users can log daily workouts.
