The UA SpeedForm Gemini 3 RE is a smart running shoe designed to prevent injuries in runners. The footwear from Under Armour also syncs to an app (UA MapMyRun), so wearers can monitor their fitness and adjust their workouts.
Essentially, the shoes are a form of wearable technology that tell you if you are fit enough to run. This is possible with a simple jump test. While wearing the tech-infused trainers, you can jump around to assess how intense your next run should be.
The UA SpeedForm Gemini 3 RE have optimized battery power and therefore doesn't require any charging. The shoes also tell you when their life is up and it is time for a new pair (after 400 miles).
