Price Comparison
When it comes to pricing, the New Balance Women's Fresh Foam 520 V9 Running Shoe is priced at $59.99, while the Under Armour Women's Charged Assert 10 is available for $54.95. This makes the Under Armour option about 17% cheaper than the New Balance shoe. Despite the slight difference in price, both products are positioned as quality running shoes. The New Balance shoe reflects its pricing with features geared towards comfort and durability, while the Under Armour shoe offers a more budget-friendly option without sacrificing essential features.
Comfort and Cushioning
Both shoes prioritize comfort, but they utilize different technologies to achieve it. The New Balance Women's Fresh Foam 520 V9 features fresh foam cushioning that provides responsive comfort mile after mile, making it an excellent choice for longer runs. In contrast, the Under Armour Women's Charged Assert 10 incorporates Charged Cushioning, which uses compression molded foam for ultimate responsiveness and durability. While the New Balance shoe emphasizes a lightweight feel at just over 200 grams, the Under Armour shoe weighs 8.9 oz. This difference in design may cater to different runner preferences regarding comfort and responsiveness.
Breathability
Breathability is a key feature in running shoes, and both options excel in this area. The New Balance Women’s Fresh Foam 520 V9 has a breathable mesh upper that keeps feet cool and dry during workouts, which is essential for longer runs. The Under Armour Women's Charged Assert 10 also boasts a lightweight, breathable mesh upper with synthetic overlays for added support and durability. While both shoes are designed to keep your feet comfortable, the New Balance shoe may offer a slight edge for those prioritizing ventilation and temperature control.
Weight Considerations
Weight can significantly impact performance in running shoes. The New Balance shoe is particularly lightweight, weighing just over 200 grams, which allows for minimal resistance during runs. Conversely, the Under Armour shoe weighs 8.9 oz, which is still relatively light but may feel bulkier to some runners. If you value a feather-light shoe for speed, the New Balance Women's Fresh Foam 520 V9 may be the better choice, while the Under Armour option offers a balance of weight and durability.
Durability and Traction
Durability and traction are critical for runners who frequently change terrains. The New Balance Women’s Fresh Foam 520 V9 features a durable rubber outsole that provides reliable traction on various running surfaces, making it suitable for both road and light trail running. The Under Armour Women's Charged Assert 10 also includes a solid rubber outsole that covers high-impact zones, enhancing durability while remaining lightweight. Both shoes demonstrate a commitment to providing traction and durability; however, the New Balance shoe’s design may cater better to those looking for versatility across different running conditions.
Fit and Adjustability
When it comes to fit, both shoes offer adjustable closures for a secure fit. The New Balance Women’s Fresh Foam 520 V9 features a simple lace-up closure that allows for easy adjustments to ensure comfort. Similarly, the Under Armour Women's Charged Assert 10 uses a standard tie lace type, providing users with the ability to customize the fit. However, the New Balance shoe's emphasis on a snug fit, combined with its lightweight design, may appeal more to runners looking for a second-skin feel.
Style and Aesthetics
Style is subjective, but it can influence purchase decisions. The New Balance Women’s Fresh Foam 520 V9 comes in a striking Black/Castlerock/Metallic Rose colorway, appealing to those who want a stylish shoe that stands out. On the other hand, the Under Armour Women's Charged Assert 10 is available in a classic Black/Black/White color scheme, which may attract those who prefer a more understated look. Both designs have their merits, but the choice largely depends on personal style preferences.
Which should you buy?
In comparing the New Balance Women's Fresh Foam 520 V9 Running Shoe and the Under Armour Women's Charged Assert 10, the decision ultimately hinges on your specific needs and preferences. If you are looking for a lightweight shoe with exceptional comfort and breathability, the New Balance option, despite its higher price of $59.99, may be worth the investment. However, if you prioritize a more budget-friendly choice without sacrificing essential features like cushioning and durability, the Under Armour shoe priced at $54.95 is an excellent option. Each shoe brings its unique strengths to the table, so consider your running style and requirements before making a final decision.
