The UNDER ARMOURMen's HOVR Sonic 4 is a lightweight, neutral daily trainer designed for road runners who want a balance of flexibility and responsive cushioning. It functions as a versatile "all-around" trainer, offering enough comfort for longer distance runs while remaining snappy enough for faster pace intervals.
Key Performance Specifications
Midsole Technology: Uses standard UA HOVR™ foam encased in a compression mesh Energy Web to absorb road impact and deliver high energy return.
Weight & Drop: Weighs approximately 9.92 oz (men's size 9) with a standard 8mm heel-to-toe drop.
Upper & Fit: Engineered with a highly breathable, lightweight mesh upper. The tongue features stretchable internal support wings attached to the footbed to maintain a secure, slip-free lockdown.
Support: Features a one-piece heel construction reinforced by a rigid external TPU heel counter to lock the heel in place and prevent chafing.
Outsole Durability: Employs lightweight blown rubber under the forefoot for springy toe-offs alongside high-abrasion carbon rubber beneath the heel to prevent premature wear.
Digital Connectivity: Contains an embedded Bluetooth sensor that pairs with the UA MapMyRun™ app. This allows runners to track metrics like cadence, stride length, and foot strike angle for real-time form coaching. (Note: In-app connectivity for this specific legacy model was scheduled to sunset by Under Armour)
