Updates to Under Armour Threadborne Slingflex

  • The very stylish Under Armour Threadborne Slingflex features the solid yet flexible rubber outsole for high resistance to abrasion and effective traction properties.
  • In its midsole, the Molded Micro G® footbed and the Two-piece Charged Cushioning® system deliver an unparalleled level of comfort and responsiveness. The technologies provide a well-cushioned environment to the user and at the same time ensure a high energy return while running.
  • The ThreadborneTM textile upper, along with the woven-in Dyneema® fibers, results in a very breathable and healthy environment for the runner inside the shoe. Also, the interior feels very soft and smooth against the skin.

Under Armour Threadborne Slingflex size and fit

The Under Armour Threadborne Slingflex fits true to its length and width. The shoe has a standard running length for both the men’s and women’s versions. In terms of width, this neutral running footwear has the standard width of D for men and B for women.


Solid rubber is placed in the outsole unit of the Threadborne Slingflex. Its design is that of a footprint or the pressure points of the underfoot. Its purpose is to provide traction and to shield the midsole foam from the potentially abrasive nature of the surface.

Flex grooves make the platform more flexible. They basically allow the sole unit to follow the natural movement of the foot as it goes through the gait cycle.


The Under Armour Threadborne Slingflex houses the Molded Micro G® footbed for a perfect blend of cushioning and responsiveness. The material also maintains the needed friction inside the shoe to avoid wobbling within the foot-chamber.

The two-piece Charged Cushioning® consists of layers of foam that have differing densities. The topmost one that has lower density works in association with the denser foam at the bottom to provide utmost comfort and underfoot support. The dual-density system provides the level of comfort and flexibility that is difficult to beat.


The upper of ThreadborneTM textile provides a glove-like yet breathable fit to the user. The compression-like material enables the upper to flexibly adjust itself to the changing foot movements, thereby promoting a snug fit and also the natural gait for the runner.

The woven-in Dyneema® fibers in the upper further strengthen the material and ensure a long-lasting performance for the user in terms of comfort and durability.

The Under Armour Threadborne Singflex features the cushioned mesh tongue. It’s attached to the footbed with the help of elasticized support wings. It holds the foot and keeps it in place. Pores on its façade allow air to enter the shoe and maintain a cool and dry environment.

The Lace-up closure adjusts the fit in accordance with the preference of the runner.

The internal heel counter with very soft cushioning offers maximum protection and steadiness for the rear section of the foot. Also, it adds reinforcement to the shoe’s structure.

The breathable fabric lining across the upper offers a soft in-shoe feel to the user. At the same time, its thin nature encourages ventilation.
