    It’s a versatile shoe that offers great proprioceptive feel for the ground, just enough cushioning and a significant amount of energetic pop in every stride.

  • 82 / 100 by Believe in the Run • Thomas Neuberger • Level 4 expert

    Let’s cut to the chase, The Under Armour Speedform Gemini 2 and Gemini are the same shoe (twins, get it?) with minor updates.

  • 83 / 100 by Runners Need • James Reader • Level 3 expert

    This innovation is inspired by early spacesuit design and offers an incredibly precise fit and amazing comfort.

    A Workhorse – They aren’t used for the beauty. They do the tough work on the farm.

  • 79 / 100 by Impact Magazine • Impact Magazine • Level 3 expert

    It feels like a bit bigger base of support with slightly more cushioning than I’m used to, but this shoe works for all runners, whether they are getting into the sport or need to put in lots of marathon miles.

  • 87 / 100 by Run Mum • Run Mum • Level 1 expert

    This shoe is comfortable, it molds to you, and gives you the support and cushioning you need to make it through those k’s.

  • 87 / 100 by The Girl That Runs • Zoe • Level 1 expert

    I felt very light on my feet and like I was quite bouncy and I have enjoyed running in the shoes.

  • 83 / 100 by Samantha Murphy • Samantha Murphy • Level 1 expert

    Although the shoes aren't perfect, its unique take on fitness tracking is the start to something much bigger for the category as we know it now.

  • 82 / 100 by 10000 Steps Daily • Tom Crandall • Level 1 expert

    For me the Gemini 2 has been one of the best running trainer/distance shoes I have worn and I have worn a lot.  The shoes fit literally like a glove.

  • 80 / 100 by Charm City Run • Ian Johnston • Level 1 expert

    Just lace up the shoes and go, or as UA says, Run Free.

  • 80 / 100 by Wear Tested • Wear Tested • Level 1 expert

    The TPU heel counter has been updated; it wraps the heel more for additional support. 

  • 78 / 100 by DC Rainmaker • DC Rainmaker • Level 1 expert

    The only complaint I had is more of a shoe-fit item than anything else, which is definitely going to vary from person to person (for me, it rubs a bit on the upper right portion of one of my feet). 

  • 60 / 100 by Mike Prospero • Mike Prospero • Level 1 expert

    The only major issue I had with the Gemini 2 is that its insole isn't removable. If you need an orthotic or some other custom insole, you won't be able to use it with the Gemini 2.

Updates to Under Armour SpeedForm Gemini 2

  • The 2nd version of the SpeedForm Gemini from Under Armour may look bulky, but it’s flexible and responsive. This update doesn’t look all that different from its predecessor, but its changes can be found in how it functions and how it supports the foot.
  • The most immediate change for this version of the series is that its forefoot area is more spacious. It definitely allows the toes to spread more naturally and get some wiggle space. Its round shape is accommodating and agreeable to the front section of the foot.
  • The Ortholite technology is embedded in the sole unit. Its anti-microbial and anti-moisture capabilities help in making the platform healthier for the foot.
  • The mid-sole platform makes use of a dual-layer foam that features a combination of two Under Armour sole technologies. Cushioning, responsiveness and sure performance are part of the service rendered by this robust mid-sole unit. The mid-foot even has a support unit that lightly cradles it.
  • Two rubber compounds make up the durable outsole layer of this running shoe. Protection from abrasion and wear is only a part of what it can do for the sole unit. The forefoot section even adds a bit more cushioning to support each toe-off.

Under Armour SpeedForm Gemini 2 size and fit

The Under Armour Speedform Gemini 2 has a standard running shoe length. It comes in a variety of sizes that correspond to the regular measurements for length. It has a medium width when it comes to its heel, forefoot and mid-foot sections. It can accommodate those with medium-sized feet. The semi-curved shape follows the natural curvature of the foot.


Outsole

The outsole unit makes use of carbon rubber as its main protective layer. It provides durable protection against wear and tear. It also delivers traction, which is important when it comes to gaining control over the surfaces.
Blown rubber is placed particularly in the forefoot area. While also delivering reliable traction, it gives a bit of cushioning that makes each toe off springier and well-supported. It’s a responsive rubber material that doesn’t sacrifice flexibility.

The flex grooves are placed anatomically. They’re designed to afford the foot more natural freedom of movement. It doesn’t restrict the motion of the wearer, therefore making each step much smoother and more natural.


Midsole

The Dual-Layer cushioning of the mid-sole contains the Charged Foam, which is a material that can absorb impact shock and then convert that into energy that can be used to make the next step more explosive. The next layer of cushioning in the mid-sole is the Micro G. This foam has bounce-back mechanics and impact protection capabilities, so each heel strike becomes well-supported.

A thermoplastic unit called the Supportive TPU Shank in the mid-sole supports the mid-foot section and stabilizes it, so that mild over-pronated foot motion is reduced.


Upper

The upper unit uses the Perforated Mesh. This breathable material uses ultrasonic seals to deliver a next-to-foot experience that’s not irritating to the skin.

The Ultrasonic Welded Seams with Bemis Tape hugs the foot and keeps it in place. The material is non-irritating, so the runner can experience a consistently soft yet robust coverage, even when wearing the shoe without socks.

The 4D Foam sock liner follows the contours of the runner’s foot. It prevents slippage, but it also fully supports the entire curvature of the underfoot, making the platform more agreeable and comfortable.

A Recessed OrthoLite Sock Liner is placed directly into the mid-sole. Its anti-microbial properties and its capability to wick off moisture bring a healthy underfoot platform.
