Zappos, MapMyFitness Will Tell You When You Need New Running Shoes

Zappos and training app MapMyFitness are teaming up to ensure runners are never logging miles on worn-out shoes. The two companies announced last week a new feature called Gear Tracker in the MapMyFitness app for Apple iOS users. The feature lets users estimate when their shoes are too worn to run in and then gives them the option of buying a new pair of shoes directly from the fitness tracking app. The companies expect to bring the same feature to Google's Android before the end of the year.
