Price Comparison

This notable price difference could be a deciding factor for budget-conscious consumers. While both shoes are designed for comfort and performance, the ALTRA shoe may appeal to those willing to invest more for features that promote foot health, as it has received the American Podiatric Medical Association Seal of Acceptance. In contrast, the Under Armour model offers a solid value proposition for those seeking a reliable running shoe at a lower price.
Brand Reputation
ALTRA is known for its focus on foot health and comfort, evident in the FWD VIA's design, which prioritizes natural foot movement. The brand has built a reputation among running enthusiasts who value these aspects. On the other hand, Under Armour has established itself as a leader in athletic gear, with the Charged Assert 9 being a popular choice among casual runners and fitness enthusiasts. This shoe ranks 2002 in bestseller rank, indicating a solid market presence. Both brands have loyal followings, but ALTRA's niche focus on foot health may attract a specific demographic of runners.
Comfort and Fit
Comfort is a key feature for both the ALTRA FWD VIA and the Under Armour Charged Assert 9. The FWD VIA employs Altra EGO FLO supercritical midsole foam, delivering a lightweight and soft underfoot feel. It also features a rocker shape designed to enhance propulsion with each step. Conversely, the Charged Assert 9 emphasizes a plush step-in feel, thanks to foam padding around the ankle and a molded liner. This ensures a comfortable fit right out of the box, eliminating the need for a break-in period. Ultimately, both shoes offer excellent comfort, but the FWD VIA leans toward advanced cushioning technology, while the Charged Assert focuses on immediate comfort.
Performance Features
For performance, the ALTRA FWD VIA showcases its benefits through a rocker design that aids in toe-off efficiency, promoting a natural stride. This shoe is ideal for runners looking to enhance their performance over long distances. In contrast, the Under Armour Charged Assert 9 is designed for a softer ride with its Charged midsole, providing balanced impact protection. The breathable upper mesh also enhances airflow, keeping feet cooler during workouts. While both shoes support running and training, the FWD VIA may cater more to serious runners, whereas the Charged Assert 9 is suitable for a variety of activities, including casual walks.
Stability and Support
Stability is crucial in running shoes, and both models approach this aspect differently. The ALTRA FWD VIA focuses on a natural fit, allowing for a more natural foot movement that can enhance overall stability during runs. Conversely, the Under Armour Charged Assert 9 features reinforced overlays that improve midfoot support, helping to keep the foot centered during training or longer walks. This added support can be particularly beneficial for newer runners or those engaging in light training. While both shoes provide stability, the ALTRA is designed for a more natural motion, whereas Under Armour offers structured support.
Breathability
Breathability is a significant factor for runners, especially during warm-weather activities. The Under Armour Charged Assert 9 excels in this area with its lightweight mesh upper, designed to boost airflow and keep feet cool. This feature is particularly advantageous for those engaging in intense workouts or runs in hot conditions. On the other hand, while the ALTRA FWD VIA provides comfort through its cushioning, it does not specifically highlight breathability in its features. This could be a consideration for runners who prioritize ventilation as a critical aspect of their footwear.
Design and Aesthetics
The aesthetic appeal of running shoes can influence purchasing decisions. The ALTRA FWD VIA comes in a light gray color, presenting a sleek and modern look that may appeal to style-conscious runners. In comparison, the Under Armour Charged Assert 9 is available in a classic black and white color scheme, offering versatility that pairs well with various athletic outfits. While both designs are functional, the choice may ultimately come down to personal preference regarding color and overall style, with the ALTRA focusing on a contemporary vibe and Under Armour providing a timeless classic.
Which should you buy?
Choosing between the ALTRA Women's FWD VIA and the Under Armour Women's Charged Assert 9 depends largely on your running needs and budget. If you prioritize advanced features that promote foot health and are willing to invest in a higher-priced shoe, the ALTRA FWD VIA is a strong contender. Alternatively, if you're looking for a reliable and comfortable shoe at a lower price point, the Under Armour Charged Assert 9, which is about 42% cheaper, offers excellent value with solid performance. Consider your running habits, style preferences, and budget to make the best choice for your needs.
