Price Comparison
The Saucony Women's Endorphin Pro 4 Sneaker retails for $130.66, while the Under Armour Women's Charged Assert 9 is priced significantly lower at $57.95. This makes the Charged Assert 9 about 56% cheaper than the Endorphin Pro 4. For budget-conscious consumers or those new to running, the Under Armour model presents a more accessible entry point into quality running shoes without sacrificing essential features. The price difference may influence buyers, especially if they are looking for value and functionality in their footwear.
Performance Features
When it comes to performance, the Saucony Women's Endorphin Pro 4 is designed for speed with features like a carbon plate and PWRRUN technology. This shoe is built for race-day performance, offering a snappy feel that can enhance racing efficiency. In contrast, the Under Armour Women's Charged Assert 9 focuses on comfort and support, featuring a Charged midsole that provides balanced impact protection. While the Endorphin Pro 4 is ideal for those seeking high-speed runs, the Charged Assert 9 may be better suited for everyday training or casual running, making it versatile for different user needs.
Comfort and Fit
Comfort is paramount in running shoes, and both models approach this need differently. The Saucony Women's Endorphin Pro 4 emphasizes a lightweight design that promotes a fast feel, but it does not specifically highlight cushioning features. Meanwhile, the Under Armour Women's Charged Assert 9 boasts a plush step-in feel with foam padding around the ankle and a molded liner for a soft, cushioned experience. This makes the Charged Assert 9 particularly appealing for those who prioritize comfort during longer runs or walks, suggesting it may be the better choice for users who value long-term wearability.
Breathability
Breathability is another critical factor in running shoe performance, especially in warmer conditions. The Saucony Women's Endorphin Pro 4 does not specifically mention breathability features, potentially limiting comfort in hot weather. On the other hand, the Under Armour Women's Charged Assert 9 features a lightweight mesh upper designed to boost airflow, keeping feet cooler during runs or workouts. For runners who often train in warmer climates, the Charged Assert 9’s breathability could provide a significant advantage in maintaining comfort and performance.
Stability and Support
Stability is vital for runners to prevent fatigue and injury. The Saucony Women's Endorphin Pro 4 is engineered for speed but lacks specific mention of stability features. In contrast, the Under Armour Women's Charged Assert 9 includes reinforced overlays that improve midfoot support, helping to keep the foot centered during runs. This added support can enhance confidence in stride, particularly for newer runners or those engaging in light training. Thus, for stability-focused buyers, the Charged Assert 9 is a more secure option.
Traction
Traction can significantly impact a runner's performance on different surfaces. The Saucony Women's Endorphin Pro 4 utilizes advanced technologies to enhance performance but does not explicitly mention traction features. Conversely, the Under Armour Women's Charged Assert 9 is equipped with a rubber outsole designed with a flexible tread pattern to increase traction on various surfaces. This feature may appeal to those who engage in mixed-terrain running or workouts, where reliable grip is essential for safety and performance.
Aesthetics and Design
Aesthetics play a role in a runner's choice of footwear, and both models offer distinct styles. The Saucony Women's Endorphin Pro 4 comes in a striking Mirage/Citron colorway, appealing to those who enjoy bold designs. The Under Armour Women's Charged Assert 9, available in a classic Black/White combination, caters to a more understated look that tends to match various athletic outfits. While personal style preferences will vary, the choice between the two may come down to whether a runner prefers vibrant colors or timeless designs.
Which should you buy?
Ultimately, the decision between the Saucony Women's Endorphin Pro 4 and the Under Armour Women's Charged Assert 9 will depend on individual needs and priorities. If you are looking for a lightweight, high-performance shoe tailored for speed and race day, the Endorphin Pro 4 is an excellent choice despite its higher price point. However, if you prioritize comfort, breathability, and affordability for daily training or casual use, the Charged Assert 9 presents a compelling option at a significantly lower price. Each shoe serves its purpose well, so assess your running style and preferences before making a choice.
