As a general rule, I have been told 300-500 miles should be the life expectancy of a pair of running shoes. I had just passed 300 miles in my Brooks Ghost, so I stopped by Charm City Run. My buddy Tom hooked me up with a pair of the new Under Armour Speedform Gemini 2 Record - a shoe that tracks distance (and more), untethered - and asked me to try them out.
Under Armour's latest move in wearable technology is finally here. With a retail price of $149.99, this shoe comes equipped with the ability to track it's own mileage and download the stats to Map My Run - without being tethered to another device!
