Price Comparison
The ASICS Women's Gel-Contend 9 Running Shoes are priced at $64.95, while the Under Armour Women's Charged Assert 9 comes in at $57.95. This makes the Under Armour option about 17% cheaper than the ASICS pair. When considering budget, the Charged Assert 9 provides a more economical choice for those looking to invest in a reliable running shoe without breaking the bank. However, the slight price difference could be justified depending on the specific features and comfort each shoe offers to the runner.
Comfort and Cushioning
When it comes to comfort, both shoes excel but in different ways. The ASICS Women's Gel-Contend 9 features rearfoot GEL technology that enhances impact absorption, providing a softer feel at footstrike. This shoe also incorporates an OrthoLite sockliner for excellent step-in comfort. In comparison, the Under Armour Women's Charged Assert 9 boasts a Charged midsole that delivers balanced impact protection, making it especially suitable for newer runners. Both shoes prioritize comfort, but the ASICS offers superior cushioning technology, which may appeal to those with a focus on long-distance runs.
Breathability
Breathability is a crucial factor for running shoes, and the Under Armour Women's Charged Assert 9 has a slight edge in this category. Its lightweight mesh upper enhances airflow, keeping feet cooler during runs and workouts. While the ASICS Women's Gel-Contend 9 also features a jacquard mesh upper that improves airflow, it may not be as breathable as the engineered mesh of the Under Armour shoe. Anyone running in warmer conditions may find the Under Armour option particularly beneficial for maintaining comfort during their activities.
Support and Stability
Both shoes provide commendable support, but they approach it differently. The ASICS Women's Gel-Contend 9 utilizes synthetic stitching on the overlays to improve support and stability, making it a solid choice for varied terrains. On the other hand, the Under Armour Women's Charged Assert 9 includes reinforced overlays that help keep the foot centered, promoting stability during light training or longer walks. The ASICS might be preferable for more challenging terrains, while the Under Armour shoe excels in providing stability for casual workouts or walks.
Traction and Outsole Design
Traction can significantly impact a runner's performance, and both shoes have unique outsole designs to enhance grip. The ASICS Women's Gel-Contend 9 features a synthetic rubber outsole with Trusstic Technology, which contributes to exceptional stability. Conversely, the Under Armour Women's Charged Assert 9 is equipped with a rubber outsole that boasts a flexible tread pattern, ensuring steady movement on pavement or treadmills. Runners who frequently switch between various surfaces may benefit from the ASICS' emphasis on stability, while the Under Armour's grip is excellent for smoother terrains.
Weight and Flexibility
Weight and flexibility are essential for running shoes, especially for those who prioritize speed. The Under Armour Women's Charged Assert 9 is designed with lightweight materials, which helps boost airflow and promotes a more agile stride. The ASICS Women's Gel-Contend 9, while comfortable, is slightly heavier due to its additional cushioning technology. However, the flex grooves in the ASICS' outsole improve flexibility, allowing for a more natural foot movement. Runners who prefer a lighter shoe for speed may lean towards the Under Armour model, while those seeking a balance of cushioning and flexibility might favor the ASICS.
Design and Aesthetics
In terms of aesthetics, both shoes present appealing designs tailored to different tastes. The ASICS Women's Gel-Contend 9 is available in a lilac hint and bluebell color combination, providing a stylish yet sporty appearance. In contrast, the Under Armour Women's Charged Assert 9 comes in a classic black and white colorway, which may appeal to those looking for a more versatile and understated option. Ultimately, the choice between these two designs will depend on personal preference, but both shoes maintain a modern look suitable for various activities.
Which should you buy?
Choosing between the ASICS Women's Gel-Contend 9 and the Under Armour Women's Charged Assert 9 ultimately depends on individual priorities. The ASICS shoe excels in cushioning and overall comfort, making it ideal for runners focused on long distances or varied terrains. However, the Under Armour option is about 17% cheaper and offers excellent breathability and a lightweight feel, which can be particularly appealing for casual workouts or warm-weather runs. If your priority is budget and breathability, the Under Armour is the better buy, but for those seeking enhanced cushioning and support, the ASICS may be worth the extra investment.
