Personalized Training, Democratized.

As much as you would personally benefit from a personal trainer, your wallet begs to differ. However, with the Under Armour Women's Speedform Gemini 3 City RE Running Shoe, you get the personalized training you need in order to run smarter, not harder.

To achieve such a feat, the Gemini 3 features a built-in chip that tracks real-time run data (time, cadence, duration, distance, and splits). This chip then syncs with UA's MapMyRun app and in turn, offers you customized training plans and allows you to look back on your stats. A simple preliminary test called The Jump Score reportedly measures muscle fatigue and recovery rate, and as a result suggests how intense your run should be. Additionally, it's important to note two things: the UA MapMyRun app is free for a year, and the built-in chip ensures that you're able to run with-or-without your phone. Not to mention, the built-in-chip doesn't require charging and ensures that you're able to cruise with or without your phone.

And, in keeping with the original Gemini 3 design, this running shoe provides dependable performance. A seamless design cuts down on hot spots or chafing while simultaneously offering passive ventilation and comfort. The Threadborne midfoot panel offers structural integrity, and the sockliner wicks away moisture and doubles down on comfort. A Charged Cushioning midsole promotes enhanced energy return through transitions, attenuates shock, and maintains a responsive feel underfoot, making the Gemini 3 ideal for fartlek workouts and endurance runs alike. Not to mention, the Micro G heel unit is designed specifically for runners who have an aggressive heel strike, yet won't prohibit the natural mobility of runners who don't.

Most comfortable Shoes Ever

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: 8

I got these as a mix of a gym, casual and trail running shoe. I was extremely curios about the step counter in the shoe. I haven't ever had a chance to motivate myself with that kind of technolgy! The idea of the chip in the shoes connected to your smart phone seems like a great idea but I just got frustrated with the App.
That being said these are the most comfortable shoes I've ever gotten. They are very low profile and you can feel the energy get transferred into each upcoming step. I didn't have to adjust my gate the first time running in these which was awesome!

I would love to purchase these without the chip just for the comfort and support of this shoe! I got a size 8 since I got them for working out and running I needed to allow my feet to swell! I wear a size 7.5 to an 8. I could have gotten away with a 7.5 but for heavy work outs I'm happier with the 8!
