The outsole is exceptionally durable, with thick, hard rubber that resists wear. However, lab tests and user feedback consistently report poor durability in the upper and heel padding, which are prone to early wear and tear. Overall durability is mixed: great outsole, weak upper.
The Under Armour Charged Assert 9 is widely regarded by experts and users as a budget-friendly, comfortable, and durable shoe best suited for general daily training and casual fitness use. Its Charged Cushioning midsole provides adequate shock absorption and comfort for everyday runs and walking, but the shoe lacks the advanced cushioning, responsiveness, and upper durability required for long runs or faster-paced workouts. The outsole is highly durable and offers good traction on roads and gym surfaces, but the upper is prone to premature wear and lacks breathability, limiting its suitability for extended efforts or hot conditions. The shoe is stable and secure for easy and recovery runs, but its weight and basic foam make it less ideal for tempo runs or racing, where lighter and more responsive shoes are preferred. It is not designed for trail running, as it lacks aggressive tread and protection for technical terrain. Expert consensus from RunRepeat, RunningShoesGuru, and user reviews on Amazon and Reddit consistently position the Charged Assert 9 as a solid entry-level or secondary trainer for short to moderate distances, gym use, and walking, but not for serious performance running.
Ideal for Best suited for beginner to intermediate runners or fitness enthusiasts who prioritize comfort, affordability, and versatility for short runs, gym workouts, or all-day wear. Not recommended for high-mileage runners or those seeking advanced breathability and upper durability.
The Charged Assert 9 is designed for runners seeking a balance of flexibility and cushioning. The shoe offers a secure midfoot lockdown due to leather overlays, but the upper mesh is less durable and not highly breathable. The heel and toebox fit are standard, making it suitable for most average-width feet. There are no advanced stability or propulsion features such as a carbon plate or rocker geometry. The shoe is best suited for neutral runners and daily training, not for those needing motion control or maximal cushioning.
Sizing: Generally considered true to size by most users and retailers. No widespread recommendations to size up or down. Fit is comparable to other Under Armour Charged Assert models, with a standard running shoe length and width.
