Updates to Under Armour Micro G Speed Swift 2

  • The second iteration of the Under Armour Micro G Speed Swift boasts an improvement in its overall design, thereby pushing its goal of better performance and enhanced durability for the users.
  • The upper unit of this affordable running footwear is made more breathable for heightened ventilation. Its newer design ensures instant cooling and drying of the foot throughout the running session. The solid rubber on the outsole delivers traction on various types of surfaces, even wet ones.

Under Armour Micro G Speed Swift 2 size and fit

The Under Armour Micro G Speed Swift 2 is a neutral road running shoe available in the standard medium width of D for men and B for women, respectively. As far as its length is concerned, it is advisable to go a size up. Moreover, the shoe has a spacious interior which makes it suitable for wide foot runners, as well.


The outsole features the solid rubber that is highly resistant to abrasion and aberrations. It distributes the impact shock evenly over the whole surface area, thereby reducing the risk of discomfort.

Flex grooves allow the platform to move with the natural bending of the foot as it goes through the gait cycle.


The midsole is made using the full-length Micro G® foam. This material ensures a smooth heel-to-toe transition. It also makes sure to cushion the foot throughout the running session. The Micro G foam is also used in some Under Armour running shoes.

The cushioned insole provides a feel of customized comfort to the user. It essentially adds a bit more cushioning for the underfoot.


The upper mesh material has perforations that allow for a healthy inflow and outflow of air. This feature ensures instant cooling and drying of the runner’s foot while one is out on the roads. The mesh material is light in weight and soft against the skin.

For reinforcement and enhanced durability, the upper makes use of the additional bonded film at the midfoot section. This structure, being light in weight, has hardly any impact on the overall weight of the shoe.

The lace-up closure tightens or loosens the fit, and it adheres to the preference of the wearer.

The Padded Ankle Collar and the Padded Tongue keep the foot in place. They also add some cushioning to their respective areas of responsibility.
