Good to know
- Under Armour introduces minimal changes in the 2.1 model of the SpeedForm Gemini. The latest version uses a new mesh that is quite bigger and with numerous holes. With this update, the upper promises to be more durable and with better breathability.
- The upper is not as stiff as before and should create a more form-friendly fit. It gives runners an adaptive fit that conforms to the foot with every stride.
The fit of the 2.1 SpeedForm Gemini is very similar to the earlier version. The main difference is the latest model’s more sock-like fit due to the softer upper. It has standard shoe size and with adequate space in the toe box. The substantial heel counter locks down the rear portion of the shoe while midfoot hold is sufficient.
The outsole of the SpeedForm Gemini 2.1 is very well articulated from the heel to the forefoot. There are rather deep flex grooves with clear separation between the rubber pods. This design helps with the shoe’s excellent flexibility. The outsole also uses mostly blown rubber for enhanced traction with carbon rubber in the heel for improved durability. This outsole configuration is also utilized in the Gemini 3 running shoe.
Under Armour has a very simple approach in the midsole of the SpeedForm Gemini 2.1. Running the length of this shoe is a somewhat thick Under Armour-exclusive Charged Cushioning foam. It gives the shoe adequate durability and responsiveness. For more support and stability, TPU inserts called ArchForm are located in the heel and arch areas of this shoe.
The new upper begins with a more breathable mesh that is also more adaptive. It offers better wraparound comfort and fit. The shoe has excellent heel security courtesy of a very prominent external heel counter. There is added cushioning and support as a molded and fixed sockliner is located in the shoe’s interior. Both the tongue and the ankle collar are quite thin, but lined with soft and plush fabric.
