  • Under Armour really knows how to make innovative and really nice upper as it is showcased in the introduction of the SpeedForm Fortis Twist. A soft, very breathable, and extremely comfortable fabric covers the shoe. It ensures a cool and dry run while getting compliments along the way with this sleek and sophisticated-looking shoe.
  • The Charged Cushioning makes this way in this shoe as well. It is durable, cushions impact really well with enough responsiveness for tempo runs or when piling on the miles.
  • The upper gets 360° of reflectivity for night-time or early morning runs. It uses an adjustable heel strap and a smooth external heel counter to secure the foot from extra movements.

The fit of the Under Armour SpeedForm Fortis Twist is standard with particularly good locked down feel in the heel while the midfoot has decent security. While the toe box is a bit snug, it does have enough space for the toes to splay. It runs true to size.

The outsole of the Twist version of the SpeedForm is mostly blown rubber for improved traction. A sturdy carbon rubber is located in the heel and other areas that are susceptible to wear. The outsole has good flexibility and ground contact, which should aid the transitions to become a bit more efficient.

Under Armour’s brand-exclusive Charged Cushioning is more durable, lighter, and more responsive than standard EVA. It is a bit thick and provides a soft landing spot for runners. The foam runs the length of the shoe for consistent cushioning and better transitions through the gait cycle.

The seamless upper is mostly covered by the very breathable and cottony-soft fabric upper. A heel strap and a substantial external heel counter keep the foot secured. 360° of reflectivity makes it an excellent night-time running partner. The interior features a 6mm 4D footbed for more cushioning and support. A traditional lace-up closure maintains the fit all throughout the run.
