Responsive UA HOVR cushioning reduces impact, returns energy & helps propel you forward Durable rubber outsole provides grip with flexibility where you need it most​ Built with a breathable engineered mesh upper & strategic support Feels like a cloud and fits like a glove. Under Armour took their super-springy UA HOVR cushioning and put it in a trainer that's built specifically for the gym. HOVR - Under Armour's signature cushioning technology - delivers a "zero-gravity feel" through the midsole that maintains energy return and reduces muscle fatigue. That means being able to run further and conserving more energy throughout, with the compression mesh Energy Web helping guide the foot and Achilles through its natural gait cycle. Guidance and energy conservation is only half the capability of this trainer though. Under Armour's legacy of innovation extends itself through the upper: the fast-drying, breathable knit provides a comfortable, snug fit throughout for lightweight directional strength, with a durable rubber outsole providing super grip across a range of surfaces.
