Under Armour HOVR Sonic 2 Women's Running ShoesMicrothread UpperMicrothread uppers will envelop each foot in radical breathability. The compression-like fit delivers lightweight directional strength and unmatched comfort to help you go the distance, adapting to the changing shape of your foot as it moves through the gait cycle. Enriched with moisture-managing technology, the fabric wicks sweat away from the skin for quick evaporation, so you stay damp-free and comfortable during intense exercise. The upper sits softly against the skin to produce an irritation-free fit, because UA recognise how rubbing and blisters can get you down. A ventilated midfoot panel increases breathability; its perforations improve airflow to keep you cool and comfy on longer distance days. An external heel counter wraps the rearfoot to improve stability and promote complete lockdown; it helps to anchor you to the midsole and reduce in-shoe slippage so that you can enjoy a smooth, distraction-free ride. The unique tongue construction is attached to the shoe's footbed by stretchable support wings to maintain a snug, sock-like fit throughout the foot, eliminating millimetres of movement with each stride.
