The Nike model is priced at $85.00, while the Under Armour option retails for $57.95. This significant difference in cost may appeal to budget-conscious buyers looking for reliable running shoes without sacrificing quality. Despite the lower price, Under Armour's model does not compromise on performance, making it a strong contender for those seeking value for their money.

Design and Aesthetics

In terms of design, the Nike Women's Run Swift 3 features a sleek and stylish look with a color palette of White/Black-Pearl Pink-Peony, making it visually appealing for those who prioritize aesthetics in their workout gear. On the other hand, the Under Armour Women's Charged Assert 9 comes in a classic Black/White combination, which offers versatility for various outfits. While both shoes are designed with contemporary runners in mind, the choice may come down to personal preference in color and style.

Comfort and Fit

Comfort is a critical factor for any running shoe, and both models excel in this area. The Nike Women's Run Swift 3 utilizes foam cushioning that delivers a soft underfoot feel and a plush sensation with every step. Meanwhile, the Under Armour Women's Charged Assert 9 features a soft, cushioned ride provided by its Charged midsole, which aims to enhance impact protection. The Under Armour shoe also boasts foam padding around the ankle for added comfort. For runners who prioritize a comfortable fit, both shoes present strong options, though the Nike may feel more plush initially.

Support and Stability

When it comes to support and stability, both shoes offer unique features. The Nike Women's Run Swift 3 includes Flywire cables that help secure the foot, providing additional support when the laces are tightened. This feature is particularly beneficial for runners who need extra stability during their workouts. Conversely, the Under Armour Women's Charged Assert 9 has reinforced overlays that improve midfoot support, helping the foot stay centered. Both shoes provide adequate support, but the choice may hinge on whether you prefer the Flywire system or the midfoot overlays for stability.

Weight and Breathability

Weight and breathability are essential for running shoes, especially during long runs or workouts. The Under Armour Women's Charged Assert 9 is designed with a lightweight mesh upper that boosts airflow, keeping the feet cooler and more comfortable. This feature is particularly advantageous in warm weather. The Nike Women's Run Swift 3, while not explicitly noted for breathability, incorporates design elements that typically enhance airflow. Therefore, if you prioritize a lightweight feel and breathability, the Under Armour model may be the better option.

Performance on the Track

Both shoes are designed for performance, but they cater to slightly different types of runners. The Nike Women's Run Swift 3 has a sales rank of 1650, indicating its popularity among runners who appreciate its cushioning and plush feel. The Under Armour Women's Charged Assert 9, with a sales rank of 2002, is also well-regarded, especially among newer runners due to its balanced impact protection. This suggests that while both shoes perform well, the Nike may appeal more to those who favor cushioning, whereas the Under Armour could be better suited for those just starting their running journey.

Durability and Longevity

Durability is a crucial consideration when selecting running shoes. The Nike Women’s Run Swift 3 is designed with a heel overlay for added security, which can contribute to its longevity over time. The Under Armour Women's Charged Assert 9 features a tire-inspired outsole pattern that provides flexibility and superior traction, which can also enhance its durability. Both shoes appear to be built to withstand the rigors of regular running; however, the specific features of each may cater to different running styles and preferences regarding longevity.

Which should you buy?

Ultimately, the decision between the Nike Women's Run Swift 3 and the Under Armour Women's Charged Assert 9 will depend on your personal priorities and running style. If you value cushioning and a plush feel, the Nike may be the better choice, albeit at a higher price point. However, if you're looking for a more budget-friendly option that still offers comfort and breathability, the Under Armour could be perfect for you. With a price difference of about $27.05, the Under Armour model stands out as a great choice for those seeking quality without breaking the bank.
