Price Comparison

When it comes to pricing, the Under Armour Women's Charged Assert 9 is about 17% cheaper than the New Balance Women's Fresh Foam 680 V8, retailing at $57.95 compared to $69.99. This price difference may be a significant factor for budget-conscious buyers. Additionally, the average price over the last 90 days for the New Balance shoe is $77.24, indicating that it has been more expensive historically. The Under Armour model has a 90-day average price of $63.54, making it a consistently more economical choice in the long run.

Comfort and Cushioning

Both shoes offer impressive comfort features, but they approach cushioning differently. The New Balance Women's Fresh Foam 680 V8 utilizes Fresh Foam midsole foam, which is designed to provide an ultra-cushioned and lightweight ride, ideal for runners seeking maximum comfort during long durations. In contrast, the Under Armour Women's Charged Assert 9 has a Charged midsole that balances impact protection and smoothness, making it suitable for newer runners who might appreciate a softer landing. Both models ensure comfort, but the Fresh Foam 680 V8 takes a slight edge for those prioritizing plush cushioning.

Fit and Construction

The fit and construction of the shoes also differ. The New Balance model features a precision-engineered knit upper that enhances comfort and ventilation, while its no-sew construction provides a sleek fit. On the other hand, the Under Armour model boasts a lightweight mesh upper that boosts airflow, keeping feet cooler during physical activity. The foam padding around the ankle in the Under Armour shoe offers a plush step-in feel, making it easy to wear without the need for a break-in period. This means that while both shoes aim for comfort, the New Balance may be better suited for those who prefer a seamless fit.

Durability and Support

In terms of durability and support, the Under Armour Women's Charged Assert 9 stands out with reinforced overlays that improve stability, helping the foot remain centered during various activities. This feature is particularly beneficial for light training or longer walks. The New Balance Women's Fresh Foam 680 V8, while also durable and comfortable, focuses more on providing a cushioned experience rather than stability. Both shoes feature rubber outsoles, but the Under Armour shoe's flexible tread pattern enhances traction, making it a more versatile option for varied surfaces.

Design and Aesthetics

The aesthetic appeal of both models caters to different tastes. The New Balance Women's Fresh Foam 680 V8 has a more streamlined, modern design with its knit upper, which may attract those who prefer a sleek look. Conversely, the Under Armour Women's Charged Assert 9, with its breathable mesh and padded collar, offers a more athletic appearance. The choice between the two may ultimately come down to personal style, but both shoes are visually appealing in their own right.

Performance on Different Surfaces

Performance-wise, both shoes are designed to handle different types of running and walking experiences. The New Balance model is suitable for everyday runs, workouts, and errands, thanks to its cushioned and lightweight design. In comparison, the Under Armour model excels in providing a soft and enjoyable ride, particularly beneficial for new runners or those engaging in regular walking activities. The solid construction of both shoes allows them to perform well, but the Under Armour's emphasis on breathability and grip may give it an advantage in warmer conditions.

Brand Reputation and Sales Rank

Brand reputation can influence purchasing decisions, and both New Balance and Under Armour are well-regarded in the running community. However, the Under Armour Women's Charged Assert 9 has a significantly better sales rank, sitting at 2002, compared to the New Balance's rank of 13745. This suggests that the Under Armour model is more popular among consumers, which may indicate higher customer satisfaction or preference. The sales rank can serve as a useful metric for potential buyers looking for trusted options in running shoes.

Which should you buy?

Choosing between the New Balance Women's Fresh Foam 680 V8 and the Under Armour Women's Charged Assert 9 ultimately depends on your specific needs and preferences. If you prioritize cushioning and a sleek fit for longer runs, the New Balance may be the better option. However, if you're looking for a more affordable choice with excellent breathability and support, the Under Armour model is an appealing alternative. With a price difference of about $12, the Under Armour offers great value for those new to running or seeking a versatile shoe for various activities.
