You don't have to be a professional marathon runner to know that the Under Armour Men's SpeedForm Gemini Running Shoe is a comfortable yet responsive running sneaker. So whether you're a weekend warrior or running 5k twice a week, all you'll have to do is slip into these tennies and you'll be jonesing to jet out the door and burn up the track. As a neutral running sneaker, the SpeedForm Gemini is crafted with the innovative Charged Cushioning which absorbs impact and consequently rockers your foot forward, propelling your stride and increasing your speed while simultaneously ensuring impact protection and adaptive support. The seamless heel cup with foam collar and smooth, perforated mesh upper is built with welded Bemis seam tape and a 4D Foam molded upper which encourages next to skin comfort and reduced chafing while running. Additionally, the anatomically placed flex grooves and blown out rubber outsole encourage a comfortable, lightweight ride and optimal heel to toe transition so you can focus more on having fun and less on whether or not your shoes are cramping your toes or style.
