I’ve been on a bit of a mission the last year or so to find the perfect shoe for me and as a result, have tried out lots of different brands. I had read about and researched UA shoes but had mostly found the reviews to be a tad underwhelming.
However, the Speedform Gemini 2 came out towards the top of most lists for Under Armour. And, when I saw them at a good price—l bought them for £65, some retailers are still selling for £110—I thought I’d give them a go.
From the instant you see them, you notice they are an interesting shoe.
The sole sort of splays out from the mesh upper, and they seem slightly peculiar when first worn. They are, however, really comfortable, giving enough bounce and energy return on longer runs, whilst still feeling fast enough on shorter tempo runs.
Mine are also a very striking colour, the official description is rocket red, but I would say they are more on the pink side of red in the flesh!
Aside from the colour and shape of the front of the shoes, I also found them intriguing in other ways as well.
They are marketed as for neutral runners, but they provide a good amount of support as well, as can be seen by the quite prominent plastic area on the outer back of the shoe.
This will not be to everyone’s tastes aesthetically and not required in terms of performance for most neutral strike runners. I certainly feel that this part of the shoe detracts somewhat from the overall look.
But, on the whole, looks-wise, it is a very attractive shoe.
In terms of the weight of the shoe, it is just above mid-range for a shoe in the neutral cushioned runner category, weighing 295g. Perhaps, it is mainly due to the added stability at the back of the shoes.
From my experience, the running shoe runs lighter than the 295g. It’s bouncy and springy and feels fast when you pick up the pace.
As you’ll see from the picture above, the tread on the soles is quite chunky, meaning they can also handle some off-road running as well as the tarmac.
They are wearing well too. I have done about 100 miles in these—they have mostly been used as my 2nd shoe for the last five months or so. Looking at them now, I feel they’ll easily be good for another 200-300 miles.
When it comes to fit and sizing, they run quite true to size. I wear an 8 UK, 42.5 EUR, and these are a good fit, although they have occasionally pinched me on my instep on longer runs.
This has only happened once or twice and may have been down to other factors on those days but is worth noting. The toe box is definitely wide enough, and I really like how the mesh front upper allows your forefoot to move freely.
One final point on the shoes before the summary is to watch out for the weather when wearing.
I feel they don’t run very well in the rain, the tread handles the wet ok, but the upper gets wet very quickly when splashing in any puddles and doesn’t recover well, meaning wet, cold feet for the rest of your run.
These shoes have certainly not put me off trying UA shoes again in the future. They are a funky, springy runner that provides support as well.
As noted, they have a few things that detract from the overall experience. But on the whole, they are an intriguing shoe that I have been quietly impressed with.
Good to know
- 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.
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.
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.
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. The Micro G midsole is also used in the Gemini 3 and other Under Armour running shoes.
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.
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.
