  • Lightweight
  • Maximum breathability
  • Responsive
  • Solid footing
  • Stylish
  • Not a stability shoe

Strategic placement of a variety of outsole materials provides the most durable, comfortable fit possible. Blown rubber is a responsive and lightweight material. It occupies the forefoot area of the shoe. It provides traction while adding flexibility and a bit more cushioning for the foot.

The material tends to be less dense and lighter and provides a responsive bounce. The heel section has a high-abrasion rubber. The material is dense and designed for absorption of harmful shock created with each footfall. It is a durable compound that handles shock and preserves the structure of the midsole.

It doesn’t wear out or peel off easily. The front section is made more adherent by flex grooves that promote the natural movement of runners’ feet. Runners prone to injury reported the shoes help keep them injury-free.


A few technological elements enhance the overall cushioning and fit of the shoe. A full-length Charged Foam unit cushions the foot during running sessions. It responds to the movement of the feet and gives impact protection during the landing phase.

It is designed to keep runners from premature fatiguing by returning energy to the runner. The heel section has Micro G Cushioning that absorbs foot strike impact forces and bounces forward causing a springy transition to the toe-off.

An embedded Sock Liner that follows the underfoot shape gives cushioning and support to the arch, which usually receives little attention in neutral shoes. Threadborne midfoot panels also provide arch support.


Under Armour signature, Speedform is used to create a snug fit. Speedform construction allows a glove-like fit as the upper unit conforms to the shape of the foot. The snug fit is a downfall of the shoe. It feels nearly too snug in the toe area during runs of more than 10K. The other parts of the upper are great.

The heel cup is among the most secure. Heels don’t move while wearing the shoes. The new technology seems like a flashy piece of design but adds a bit more security to the midfoot when running. An engineered mesh is used to cover the foot securely and provide breathable coverage. Environmental air is welcomed into the foot chamber to keep the environment dry and cool at all times.


The men’s version of the Under Armour Speedform Gemini 3 weighs 9.8 ounces. The average woman’s size weighs 8.3 ounces. Under Armour stripped all unnecessary elements in an effort to keep down the weight of the shoe. The shoe hits a balance between lightweight and cushion. It provides cushioning enough to carry runners safely through long runs.


The shoes are more breathable than the Gemini 2. The engineered mesh of the upper allows maximum breathability. Perforated air holes dot the heel and forefoot to increase airflow. The foot is kept dry and cool, and the risk of irritation is reduced.

A supportive band surrounding the midfoot does not have air holes but is made of a material that is highly ventilated. Runners report a comfortable feel even on hot runs, because of the shoes offering increased airflow. Engineered mesh on the toe box and tongue increase ventilation and enhance fit.


The addition of Micro G cushioning helps heel strike runners. One tester reported it made the shoes more comfortable for everyday wear but noticed nothing different from the heel or midfoot during runs. Most runners find the shoes to be extremely comfortable — many like the responsiveness of the midsole foam adapting to the foot shape. Charge Cushioning is a patented midsole that offers excellent arch support.

Runners say the shoes provide adequate comfort for long runs without worry of irritation. They say they can achieve pre-developed routines because there is no distraction caused by blisters, irritation, or seam. An embedded sock liner has been added to provide even more cushioning and work to circulate air and wick away sweat.


Consumers have expressed satisfaction with the feel, overall look, and colorway out of the box. The shoe is ideal for runners who like options. Colors include Stealth Gray, Midnight Navy, Apollo Gray, White/Black, Steel/Apollo Gray, and Cardinal/Red to name just some of the colors available.

Bright colors are offered for those who want a look that is vibrant and black and white shapes for runners looking for classic styling options. The geometric pattern of the midsole sets it apart from similarly styled shoes. Runners found the sleek and thin look to be the ideal accessory for casual outfits.


A tester has run 175 miles on speedwork, tempo runs, and workouts of 13 miles or less. The shoes are still going strong after back-to-back days of abuse. The shoes felt nearly as good on the fifth day as the first.

They are great for half marathon training. The shoes take a beating and keep up speed on tempo days. Runners are pleased with the shoe’s overall durability. The upper is breathable and extremely lightweight.

The engineered mesh stands up against the elements. It does not rip or fray. Dual midsole foams do a superb job of keeping their shape and spring. The shoes are designed for long distances. Even after long runs, the midsole foams maintain their shape.


The midsole has two technologies that grace many Under Armour shoes. They work in unison to provide responsible protection from shock impact and cushioning. The outsole of the shoe is the critical area of protection. The heel is designed to protect the shoe from wear and tear. It is lined with high-abrasion rubber that adds traction to keep runners safe when runs are slippery.


It is the materials used in the midsole that give the shoe its responsive ride. There are two midsole materials, the Micro G Unit, and the Charged Cushioning. They work together to provide a highly responsive ride that absorbs shock with each footfall and returns the energy to the wearer.

Of the two rubber compounds used, the one located in the forefoot section is more responsive than the other. One of the technology systems has a springiness that allows the feet to lift from the ground in a way that is more responsive than the other system. Dual materials are used in the outsole, but they are thin and allow runners to feel the road underneath their feet. The outsold helps runners efficiently respond to direction and pace changes.


The shoes support the runner in two ways. The design of the upper is the first key support feature. Under Armour opted to use engineered mesh that wraps the foot. It supports natural movement. A Threadborne midfoot panel helps to support the feet of the runner.

The midsole is the other supportive area. It molds to the foot’s shape which gives added arch support.to
the runner. The Gemini 3 is not the shoe for runners who need maximum support for plantar fasciitis or
pronation issues.

The midfoot gets enough support to keep moving forward but s not super stiff. The midsoles rise above
the soles of the feet. They provide a bit of a controlling foot bucket. There is not a bridge for extra push on the medial side.

The solid, large heel counter and the upper are enough support for neutral runners who have no extra needs. The wide base prevents instability issues upon landing for forefoot strikers. A short lacing system provides the rest of the stability and support. The lace holes are straps that pull the midfoot panel over the foot, then tie into the midsole. They keep the shoes from feeling detached. When the foot is at one with the shoe, runs are quicker and easier.


Most people who try the shoe are happy with its performance on the roads. It is efficient as a running shoe and a casual option. The midsole cushioning and outsole with added traction are reasons distance runners love the shoe. It provides excellent energy return that aids in preventing runner fatigue. With an outsole that is durable and powerful, it can be used for hiking on groomed trails also.


With an MSRP of $130, the shoes compete with the Mizuno Wave Rider, ASICS Cumulus, and Adidas Supernova Glide. The price puts the shoes in competition with fast, responsive cushioned options. When how long-lasting and durable the shoes are, and all the technological elements it offers are taken into consideration, the price is unbeatable. The shoes cost slightly less than the cost of the average running shoe on the market today.

It outlasts many models that are more expensive. Some colorways have been marked down to $103. Amazon sells the shoes for prices that range from $47.91 to $211. It is an excellent shoe for runners who want an everyday trainer.


The only weather conditions that cause the shoes to struggle is ice. Every shoe does. There are two outsole materials located in different areas to ensure the runner gets the highest possible level of traction. The forefoot and heel respond differently to the ground. Under Armour added traction elements in strategic places. The heel has a high-abrasion rubber designed to add additional traction. Runners find the dual outside material adds the right traction in the proper areas.

Under Armour has grasped the traction concept for running shoes. Most people don’t think about it until it’s needed. Under normal conditions, runners do not need traction as they travel up and down or front to back. Under Armour provides grip in all directions.

On the lateral side, soft rubber provides serious pull when cornering. The hard black areas beneath the balls of the feet take punishment when the impact is a bit harsher. Flex grooves in the Threadborne Slingflex permit the forefront to be in ground contact a great deal of the time to give the shoes better grip.


The rubber compound placed in the section of the forefoot adds a little more cushioning and keep the platform flexible. The laces weave into the shoe upper and provide a springy hold on the feet. The shoes move with the foot’s natural movement. The engineered mesh in the upper stretches as it conforms to the foot’s shape and provides a bootie-like snugness. The midsole foam moves freely also. It is an excellent mix of support and flexibility.


The shoe was not designed for stability. Neutral running shoes support the natural foot movement and don’t work to change or improve the gait. Runners who need assistance with under or overpronation should probably choose another shoe.


The shoe has an eight-mm drop. It provides adequate forward propulsion. Time to adapt is required by runners who usually run in traditional drop shoes. Gemini 3 has a lower drop.
