Excellent outsole flexibility

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.

A superb mix of cushioning and support

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. The Micro G foam is also used in the SpeedForm Fortis 2.1 and other running shoes from Under Armour.
