Updates to Under Armour Speedform Fortis 2

  • Under Armour serves only minor modifications in the 2nd coming of the SpeedForm Fortis. The most obvious change is a knit-like mesh that is softer and more flexible. It gives the shoe an upper that frames the runner’s foot quite well.
  • Another clear change is the heel counter. While this was located outside in the original version, Under Armour places the heel counter inside this time around. It gives the shoe a more streamlined look while maintaining the same heel support and security.
  • Lastly, the footprint is a bit wider in this shoe for enhanced stability. The shoe offers more room all over with this enhancement.

Under Armour Speedform Fortis 2 size and fit

The fit of the Under Armour SpeedForm Fortis 2 mainly resembles the original version, except that this has a more sock-like fit due to the adaptive mesh upper. There should be no complaint for those with slightly wider feet as the comfortable and roomy toe box remains there for the taking. The heel and the midfoot have sufficient locked down support. The shoe runs true to size.


Outsole

The outsole uses numerous square patterns that are separated by moderately deep flex grooves. This design gives the 2nd iteration of the SpeedForm Fortis excellent flexibility. A sturdy carbon rubber is located in areas prone to wear while blown rubber is utilized mostly around the forefoot and midfoot for better traction.


Midsole

A full-length midsole design using two of Under Armour’s best cushioning technologies lies in the heart of the SpeedForm Fortis 2. Under Armour places the Charged Cushioning right on top of the Micro G foam for a superb mix of responsive cushioning and support. The full-length design also helps the runner move efficiently and quickly through the gait cycle.


Upper

The knit-like upper gives a very precise fit in comfort and support. It is also quite breathable for a cool and dry run. The seamless upper reduces the possibilities of hot spots and irritation. Under Armour still uses a thin tongue and collar in the SpeedForm Fortis 2. A seamless heel counter keeps the foot in place. Enhanced cushioning and support are provided by a fixed, molded sockliner with moisture-wicking features.
