Dimension comparison
Design and build quality
The Under Armour Women's Charged Assert 9 features a lightweight, breathable mesh upper with synthetic overlays designed for added durability and support. This construction aims to balance airflow with structural integrity during runs. In comparison, the Under Armour Women's Charged Assert 10 utilizes a lightweight mesh upper focused on boosting airflow to keep feet cooler during workouts and warm-weather activities. Both models employ reinforced overlays, though the newer model emphasizes midfoot support to help keep the foot centered for confident strides. The build quality on both shoes reflects Under Armour's standard for neutral running shoes, prioritizing flexibility and versatility.
Cushioning and comfort
Cushioning is a critical factor for runners seeking daily comfort. The Under Armour Women's Charged Assert 9 uses a Charged Cushioning midsole that utilizes compression molded foam for ultimate responsiveness and durability. It also includes an EVA sockliner for soft, step-in comfort. The Under Armour Women's Charged Assert 10 delivers a soft cushioned ride with a Charged midsole designed for balanced impact protection. Additionally, the newer model features foam padding around the ankle and a molded liner to provide a plush step-in feel with no break-in needed. While both utilize Charged technology, the Assert 10 describes enhanced ankle padding.
Support and stability
Support mechanisms differ slightly between the two generations. The Under Armour Women's Charged Assert 9 is categorized as NEUTRAL, intended for runners who need flexibility, cushioning, and versatility. It relies on synthetic overlays for support. The Under Armour Women's Charged Assert 10 also targets neutral runners but highlights reinforced overlays specifically to improve stability. This midfoot support helps the foot stay centered during light training or longer walks. Both shoes aim to provide a stable platform without correcting gait issues, suitable for runners with neutral pronation.
Traction and outsole
Traction determines how well the shoe grips the ground during various phases of the run. The Under Armour Women's Charged Assert 9 features a solid rubber outsole that covers high impact zones for greater durability with less weight. This design choice focuses on longevity in areas subject to the most wear. The Under Armour Women's Charged Assert 10 employs a rubber outsole with a flexible tread pattern. This pattern is designed to increase traction and natural flexibility for steady movement on pavement or treadmills. Both outsoles use rubber compounds suitable for road running.
Weight and performance
Weight significantly influences running performance and fatigue levels. The Under Armour Women's Charged Assert 9 has a documented weight of 8.9 oz, providing a concrete metric for runners comparing options. This lightweight design supports the shoe's classification for flexibility and versatility. The Under Armour Women's Charged Assert 10 is described as having a lightweight grip and breathable upper, but specific weight data is not provided in the available specifications. For runners who prioritize known weight metrics for pacing and efficiency, the documented 8.9 oz of the Assert 9 offers a clear advantage.
Breathability and upper
Breathability ensures feet remain cool during extended activity. The Under Armour Women's Charged Assert 9 uses a breathable mesh upper to facilitate airflow. The synthetic overlays are placed to ensure durability without completely compromising ventilation. The Under Armour Women's Charged Assert 10 emphasizes a breathable upper where lightweight mesh boosts airflow to keep feet cooler and more comfortable. This focus on airflow is particularly noted for runs, workouts, and warm-weather activities. Both models prioritize mesh construction to manage heat buildup during exercise.
Price and value
Value is determined by the cost relative to the features provided. The Under Armour Women's Charged Assert 9 is priced at $54.95, offering a cost-effective entry into neutral running shoes with verified specs. The Under Armour Women's Charged Assert 10 is priced at $57.95, reflecting its status as the newer model in the lineup. The price difference of $3.00 may be justified for some by the updated ankle padding and midfoot support descriptions. However, the lower price of the Assert 9 combined with its specific weight and offset data provides strong value for budget-conscious runners.
Which one should you buy?
Choosing between the Under Armour Women's Charged Assert 9 and the Under Armour Women's Charged Assert 10 depends on your priorities regarding specifications and model generation. If you prefer verified performance metrics such as the 8.9 oz weight and 10mm offset, the Under Armour Women's Charged Assert 9 is the superior choice. It also offers a lower price point at $54.95.
