Updates to Under Armour SpeedForm Fortis Vent

  • The Under Armour SpeedForm Fortis Vent offers high quality coverage, lightweight performance and sure protection that’s going to last a long time. It has an appealing look that caters to the tastes of modern runners who want more kick out of the visual aspect of their running gear. It’s a shoe to enjoy when tackling the roads.
  • The upper unit utilizes a mesh material that’s lightweight and breathable. It allows air to provide a well-ventilated environment for the foot. It also has a next-to-skin design that’s non-irritating. Basically, it allows the foot to feel like it’s already wearing a sock, even when not actually wearing a sock in the first place. A lockdown fit is also afforded by add-ons that keep the foot inside the shoe at all times.
  • The mid-sole unit of the SpeedForm Fortis Vent makes use of a dual-layer foam that runs its entire length. A top layer is responsible for absorbing the impact forces during each step, and gives energy to the runner for a better stride. The foam beneath it adds cushioning and makes each take-off more explosive. A sock liner has been added and it keeps the immediate underfoot well-cushioned.
  • Durable rubber is placed in critical areas of the outsole where impact and abrasion are most commonly occurring. It shields the mid-sole from any potential damage due to frequent use or surface friction. Flex grooves allow the runner to move more naturally through the gait cycle.

Under Armour SpeedForm Fortis Vent size and fit

The Under Armour SpeedForm Fortis Vent has a standard running shoe length. It comes in sizes that adhere to the regular measurements for men and women. The width of this shoe is medium, so it is able to accommodate the runners who have medium sized feet. Its semi-curved shape follows the natural curvature of the human foot.


The outsole unit of the Under Armour SpeedForm Fortis Vent utilizes a solid rubber compound that’s highly resilient and resistant to wear and tear. It doesn’t have a substantial weight, so it won’t weigh the foot down. It is placed in areas of the foot where impact is at its most frequent. It shields the sole unit from any potential damage.

Flex grooves in the forefoot allow the foot to be free when it comes to moving naturally. They make the platform more pliable and agreeable to the shape and motion of the foot when taking off the ground.


The mid-sole unit has a dual-layer foam that’s made from a combination of the Charged Cushioning technology and the Micro G® foam system. Placed on top, the former is responsible for absorbing impact shock during the striking phase of the gait cycle. It returns the energy to the runner, making each step more enabled.

The Micro G® is a responsive foam that is able to support the stride of the wearer. It makes each landing well-cushioned, and sets the foot up towards a more explosive toe-off. The Micro G midsole is also used in the Assert 7 and other Under Armour running shoes.

The sock liner has been embedded into the cavity of the mid-sole. It further enhances the cushioning the foot receives from the platform, while also keeping sure that moisture is kept at bay.


The ArmourVent™ is a mesh material is lightweight and comfortable to the skin. It doesn’t make the runner’s foot feel like it’s in a stiff and unwieldy environment. It allows air to seamlessly enter the shoe in order to keep the foot cool and dry.

An adjustable heel strap connected to the lacing system assists in keeping the heel area in place. It prevents accidental shoe removals, which could be cumbersome to runners.

Next-to-skin comfort is perceived in the shoe’s inner chamber. Ultrasonic welded seaming with Bemis tape assures that the upper is kept secure while also preserving a comfortable and non-irritating feeling.

A seamless heel cup with silicon grip holds the rear of the foot in place and prevents accidental shoe removal.
