Under Armour Speedform Gemini

Under Armour 's SpeedForm collection is one of those families that do not go unnoticed by the runner. Especially if we have in our hands the first edition of the Gemini. A shoe for neutral runners -even mild pronators-, which stands out for its great versatility and its adaptive Charged cushioning technology.

We talk about versatility because the Under Armour SpeedForm Gemini can be perfectly categorized as a multipurpose model, since it can be used, with full guarantees, to run both medium and long distances.

Dynamic and intelligent cushioning

In the midsole of the Under Armour SpeedForm Gemini lies its star material, and the one that is positioning this model among the most outstanding for neutral runners. The Charged cushioning system, presented in a single piece, and whose most notable feature is that it is an intelligent structure, which is able to adapt and offer a different response depending on variables such as the runner's weight, speed and stride, among others. That is, the Charged Cushioning system becomes firmer if the running pace is fast, while it becomes softer and softer when running slower.

A blown rubber compound is used throughout the outsole, except for the heel area, where the American manufacturer has chosen to incorporate carbon reinforcements to improve durability. The flexion is marked by the two transversal lines in the front part, and the anatomical drawing located in the area of the bridge.

The upper of the first version of the Under Armour Gemini featuresseamless SpeedForm technology, as well asHeatGear fabric, which allows sweat to be expelled to the outside, offering better ventilation. In addition, in the heel part, as well as in the support and protection of the foot. Silicone details on the collar of the shoe also reinforce the fit in the ankle area.

And to top off all the virtues and points in favor of the Under Armour SpeedForm Gemini we must also emphasize that it is a lightweight model. Its weight is 242 grams contained in a drop of 8 millimeters. In the spectrum of neutral runners, this shoe is designed for runners who do not exceed 90 kilos in weight.

The downside of the Under Armour SpeedForm Gemini is that it comes with an integrated insole (4D FOAM), 6 millimeters and non-removable, which can be a disadvantage for athletes accustomed to running with insoles.
