Summary

We spent 8.6 hours reading reviews from experts and users. In summary, this is what runners think:

6 reasons to buy

  • The upper unit offers a durable, stretchable, lightweight and breathable coverage to the foot.
  • Many testers appreciated the next-to-skin support of the upper to enhance the comfort of the wearer.
  • The 4D Foam is a reactive layer in the sock liner that conforms to the natural shape of the foot, making the fit more precise to the user.
  • The Charged Cushioning mid-sole sponges the impact energy from landing on the ground, then converts it to an energy that the runner can use.
  • Durable rubber can be found in crucial parts of the SpeedForm Fortis, which protects it from wear and abrasion.
  • This is a very lightweight running shoe.

3 reasons not to buy

  • Some runners felt that the heel area isn’t quite supported because they experienced a bit of discomfort.
  • Others experienced their foot slide forward easily while wearing it.
  • A few had cases of blistering around the ankle area.

Bottom line

The SpeedForm Fortis from Under Armour provided many runners with a robust running experienced, albeit through a lightweight, durable and responsive design. It’s a great option for daily running experiences of those with a neutral gait.

82 / 100 based on 7 expert reviews

  • 80 / 100 by RunRepeat • Samuel Chua • Level 3 expert

    The Under Armour Speedform Fortis Vent is a moderately lightweight trainer suited for casual runners who want a fun ride on the roads.

  • 80 / 100 by Runner's World • Runner's World • Level 5 expert

    The Fortis is designed as a “fitness” shoe, meaning it will transition nicely from a run to side lunges or plyometric hops, due to its wide, flexible sole that cushions in multiple directions.

  • 88 / 100 by Believe in the Run • Believe in the Run • Level 4 expert

    The Speedform Fortis is a really comfortable, light neutral trainer.

  • 90 / 100 by Holabird Sports • Cathy Kerns • Level 3 expert

    I would recommend this shoe for runners who like a lighter shoe without sacrificing response and support.

  • 82 / 100 by Believe in the Run • Thomas/Meaghan • Level 3 expert

    There is no sockliner, there are no seams; it’s just one giant piece of (super light) material hugging your feet.

  • 78 / 100 by Wear Testers • Jarron Ramos • Level 2 expert

    When idle, the Micro G layer and 4D foam insole provide an extremely plush feel that even molds to your unique foot shape with every wear, but when active, the cushion setup morphs into a responsive ride that provides ample energy return and impact protection.

Updates to Under Armour SpeedForm Fortis

  • The Under Armour SpeedForm Fortis features the brand’s Charged Cushioning system that performs better than the regular midsole foam. It delivers the great combination of responsiveness and cushioning for a more enhanced running performance.
  • The upper of the SpeedForm also offers new innovations. It features the ArmoutVent mesh upper that provides maximum breathability. It is light, quick-drying and durable enough to stand the damaging elements on the road. It also features the seamless heel cup that delivers locked-in fit. It also has an adjustable lock donw heel strap that improves the overall fit of the shoe. Lastly, the 360° reflectivity gives increased visibility while running on low lights.

Under Armour SpeedForm Fortis size and fit

The SpeedForm Fortis is true to its size. It has a normal midfoot and feels snug in the heel. The forefoot is also spacious enough for toe splay. This shoe accommodates a wide range of runners especially those with medium-sized and slightly wide foot. The width is also normal.


Outsole

The outer sole of this shoe uses the solid rubber compound that gives reliable traction on varied surfaces and it gives protection to high wear areas for greater durability. The flex grooves are strategically designed to give flexibility, allowing the forefoot to work more naturally.


Midsole

The Charged Cushioning System is found in the midsole of the shoe. It delivers a well-cushioned and responsive ride. This cushioning is reliable enough to deliver a perfect blend of cushioning and responsiveness for a smoother transition. The 6mm 4D foam gives added cushioning and enhanced fit.


Upper

The upper of the Under Armour SpeedForm Fortis uses a breathable mesh that delivers superior breathability. It also has moisture-wicking capacity and very stretchable, delivering an adapative fit. The Total Speedform technology is also used, allowing runners to focus more on the running mechanisms rather than on the footwear itself. It also features the 360° reflectivity for an increased visibility on low-light conditions.
