Price Comparison

When it comes to price, the Under Armour Women's Charged Surge 4 is the more economical option, priced at $51.95, compared to the New Balance Women's Fresh Foam 520 V9 Running Shoe at $59.99. This makes the Under Armour shoe about 17% cheaper, allowing you to save nearly $8 on your purchase. Both shoes offer excellent features for their respective price points, but if budget is your primary concern, the Under Armour option stands out.

Comfort and Cushioning

In terms of comfort, both the New Balance and Under Armour shoes excel, but they take different approaches. The New Balance shoe features fresh foam cushioning that provides responsive comfort over long distances, which is ideal for runners who prioritize a soft landing. On the other hand, the Under Armour shoe incorporates a Charged Cushioning midsole that promises all-day comfort and responsiveness. Each shoe is designed to cater to different preferences, making it essential to consider your comfort priorities.

Design and Aesthetics

The New Balance Women's Fresh Foam 520 V9 showcases a sleek design in a Black/Castlerock/Metallic Rose color scheme, while the Under Armour Women's Charged Surge 4 offers a bright White/Distant Gray/Metallic Silver look. If you prefer a more understated style, the New Balance shoe may appeal to you. Conversely, if you want a shoe that stands out, the Under Armour's vibrant design could be the better choice. Both brands ensure that their aesthetics do not compromise functionality.

Weight and Performance

Weight can significantly affect running performance, and here, the New Balance shoe has a clear advantage, weighing just over 200 grams. This lightweight design enhances speed and agility, making it suitable for serious runners. In contrast, the Under Armour shoe weighs 10.05 oz, which is slightly heavier but still manageable for most users. If you're looking for a shoe that minimizes fatigue during long runs, the New Balance is a compelling option.

Breathability

Breathability is crucial in running shoes, particularly during intense workouts. The New Balance shoe features a breathable mesh upper designed to keep your feet cool and dry. Similarly, the Under Armour shoe also boasts a breathable mesh upper enhanced with synthetic overlays for added structure and support. Both shoes effectively address ventilation, but the New Balance may have a slight edge due to its specific emphasis on keeping feet cool during training sessions.

Traction and Durability

Both the New Balance and Under Armour shoes feature durable rubber outsoles that provide reliable traction on various surfaces. The New Balance shoe is designed for dependable grip, ensuring stability during runs. Meanwhile, the Under Armour shoe focuses on flexibility at the toe-off, offering a balance of traction and ease of movement. If your runs often take you on diverse terrain, either option will serve you well, but consider the nuances of how each shoe's outsole performs.

Bestsellers and Popularity

Popularity can be an indicator of quality and satisfaction, and both shoes are well-regarded in the market. The New Balance shoe has a bestseller rank of 3173, while the Under Armour shoe ranks slightly better at 2697. This difference suggests that more consumers are choosing the Under Armour option, potentially reflecting its appeal in terms of features and price. However, both products maintain a solid reputation among runners and casual users alike.

Which should you buy?

Choosing between the New Balance Women's Fresh Foam 520 V9 Running Shoe and the Under Armour Women's Charged Surge 4 ultimately depends on your specific needs and preferences. If you're looking for lightweight design and superior cushioning for longer runs, the New Balance shoe is a strong contender. However, if budget is your main concern, and you value a stylish design with solid comfort, the Under Armour shoe is about 17% cheaper and still offers excellent performance. Consider what features matter most to you—whether it's weight, breathability, or price—before making your decision.
