Overview of Brooks Women’s Glycerin 21 and New Balance Women’s Fresh Foam 520 V9
The Brooks Women’s Glycerin 21 is priced at $114.95, while the New Balance Women’s Fresh Foam 520 V9 is about 48% cheaper at $59.99. Both shoes cater to different preferences in the running shoe market, with the Glycerin 21 focusing on superior cushioning and comfort, and the Fresh Foam 520 V9 emphasizing lightweight versatility and breathability.
Comfort and Cushioning
The Brooks Women’s Glycerin 21 excels in comfort with its super-soft nitrogen-infused DNA Loft v3 cushioning, designed to provide a plush running experience. Runners will appreciate its maximized cushioning and smooth transitions, making it a top choice for long-distance runs. On the other hand, the New Balance Women’s Fresh Foam 520 V9 offers fresh foam cushioning that provides responsive comfort, but it may not match the plushness of the Glycerin 21. While the Fresh Foam 520 V9 is lightweight, weighing just over 200 grams, it sacrifices some cushioning for this benefit.
Fit and Support
The Brooks Glycerin 21 features a plush internal stretch bootie that surrounds the foot for a secure fit, accommodating natural foot movements during runs. This shoe is designed for neutral support, ideal for runners who appreciate a soft embrace. Conversely, the New Balance 520 V9 has a simpler lace-up closure that adjusts to fit comfortably, but it may not provide the same level of snug support as the Glycerin 21. Runners who prioritize a customized fit might prefer the Glycerin 21’s advanced design.
Weight and Performance
Weighing in at just over 200 grams, the New Balance Women’s Fresh Foam 520 V9 is engineered to be lightweight, making it suitable for speed training and casual runs. This shoe's design emphasizes quick movements without the bulk. In comparison, while the weight of the Brooks Glycerin 21 is not specified, its focus on cushioning may suggest it is heavier, potentially impacting speed. Runners seeking performance may find the Fresh Foam 520 V9 more appealing.
Breathability
Breathability is a crucial feature for running shoes, especially during intense workouts. The New Balance 520 V9 is built with breathable mesh sneakers that keep feet cool and dry, making it an excellent choice for cardio workouts. On the contrary, the Brooks Glycerin 21 also boasts a newly engineered warp knit upper that is breathable, but its emphasis is primarily on cushioning. While both shoes offer breathability, the Fresh Foam 520 V9 may be better suited for warmer conditions.
Durability and Traction
When it comes to durability, the New Balance Women’s Fresh Foam 520 V9 includes a durable rubber outsole that provides reliable traction on various running surfaces. This feature is essential for runners who frequently change terrains. The Brooks Glycerin 21, while focused on cushioning, does not explicitly mention its outsole durability. However, its design suggests that it is built for long-lasting comfort during extended runs. Runners who prioritize traction might lean toward the Fresh Foam 520 V9.
Price Comparison
At $114.95, the Brooks Women’s Glycerin 21 is a premium option compared to the New Balance Women’s Fresh Foam 520 V9, which retails for $59.99. This represents a price difference of about 48%, making the Fresh Foam 520 V9 a more budget-friendly choice for casual runners or those just starting in the sport. While the Glycerin 21 offers additional cushioning and comfort, the Fresh Foam 520 V9 provides excellent value for its price, appealing to a broader audience.
Sales Rank and Market Position
The Brooks Women’s Glycerin 21 has a bestseller rank of 29,881, indicating it is a popular choice among consumers but may not be among the top-tier options in the market. Conversely, the New Balance Women’s Fresh Foam 520 V9 boasts a significantly higher sales rank of 3,173, showcasing its popularity and acceptance among runners. This difference suggests that the Fresh Foam 520 V9 might be more favored by consumers, potentially due to its price point and versatility.
Which should you buy?
Choosing between the Brooks Women’s Glycerin 21 and the New Balance Women’s Fresh Foam 520 V9 ultimately depends on your specific needs as a runner. If you are looking for ultimate comfort and cushioning for long runs, the Glycerin 21 is the superior choice, albeit at a higher price. However, if you prioritize a lightweight shoe that offers breathability and affordability, the Fresh Foam 520 V9 is an excellent option. Consider your running style, budget, and personal preferences to make the best decision for your footwear needs.
