Under Armour's Gemini Sneakers are fitness trackers for your feet. Comfortable to wear and available in two colors (blue and red), the pair comes with tiny built-in sensors that track your distance, pace, where you're going and count calories.
The sneakers ($113) also sync up to the MapMyRun app via Bluetooth, so all fitness data is housed in one place. The best part: You don't need to carry a phone when out for a jog; the shoes store up to five workouts at a time.
