Under Armour Speedform Gemini 3 Running Shoes Developed with the innovative UA SpeedForm construction which moulds to the shape of the foot for a precision fit, eliminating all distractions. SpeedForm Upper The upper of the Under Armour Speedform Gemini 3 is constructed with engineered mesh which is used on the tongue and toe box to offer an enhanced fit and increased ventilation; keeping the feet feeling cool and dry throughout a run. Equipped with the innovative Under Armour SpeedForm construction, it moulds to the foot for a precision fit; reducing in-shoe slippage for a smooth, distraction-free ride. You feel it instantly, from UA SpeedForm's perfect moulded heel cup to the textiles that wrap your foot in speed. Lastly, fitted in the upper is an internal heel counter which provides a locked-in fit and stability as you move. Charged Cushioning Midsole UA's Charged Cushioning resides in the midsole. The ultimate advancement in energy, it absorbs the impact of your foot strike and converts it into a level of responsive comfort you've never felt before. The Micro G heel unit helps to increase protection, while the embedded sockliner adds cushioning, support and seamless comfort. For added stability, the midsole also features a threadborne midfoot panel which provides structure and distinct style. High Abrasion Rubber Outsole The outsole is developed with blown rubber. Placed under the forefoot, it is lightweight yet incredibly responsive. High-abrasion rubber is placed under the heel to help absorb ground contact and increase the shoe's durability.
