Considering how small and simple the Milestone Pod is, the amount of data you get from it is pretty substantial. Simply lace the device onto your shoe and hit the road. At the end of your workout, you will have access to a virtual smorgasbord of information about your running style, including footstrike, cadence, stride length and leg swing—just to name a few. The product app also tells you ideal stats, so you know how far away you are from perfect form.
