The ASICS Women's Gel-Kayano 31 Running Shoes are priced at $124.95, while the Brooks Women’s Glycerin 21 Neutral Running Shoe is slightly cheaper at $114.95, making it about 8% less expensive. This price difference could be a deciding factor for budget-conscious buyers who are looking for quality running shoes without breaking the bank. Notably, the ASICS model has a higher average price over the last 90 days at $162.22, indicating that its current price may be a good deal compared to its typical market value.
Comfort and Cushioning
In terms of comfort, the Brooks Glycerin 21 is designed for those seeking "super-soft cushioning for supreme comfort." It features nitrogen-infused DNA Loft v3 cushioning, which is optimized to be lightweight, responsive, and durable. This makes it an excellent choice for runners looking for maximum plushness during their runs. On the other hand, the ASICS Gel-Kayano 31 incorporates FF BLAST PLUS ECO cushioning and PureGEL technology to provide a cloud-like comfort experience. Both shoes prioritize comfort, but the Brooks may appeal more to those who prioritize softness above all.
Stability and Support
When it comes to stability, the ASICS Gel-Kayano 31 stands out with its 4D GUIDANCE SYSTEM feature, which helps create adaptive stability for a more balanced stride. This can be particularly beneficial for runners who need extra support during long-distance runs. Conversely, the Brooks Glycerin 21 offers neutral support, making it ideal for runners who prefer a more natural foot movement without added structural constraints. This difference in support style can greatly influence a runner's experience, depending on their personal preference for stability versus neutrality.
Fit and Design
The ASICS Gel-Kayano 31 features an engineered mesh upper that enhances breathability and includes a knit heel pull tab for easy on and off. This thoughtful design makes it user-friendly and enhances the overall running experience. In comparison, the Brooks Glycerin 21 boasts a plush internal fit with an internal stretch bootie that moves with your foot, ensuring a comfortable and accommodating fit during runs. While both designs aim for comfort and breathability, the ASICS may be slightly easier to put on and take off due to its knit heel pull tab.
Breathability
Breathability is a vital factor for running shoes, especially during longer runs. The ASICS Gel-Kayano 31’s engineered mesh upper is specifically designed to improve airflow, helping to keep the feet cool and dry. The Brooks Glycerin 21 also features a newly engineered warp knit upper that allows for breathability while maintaining a flexible fit. Both shoes are designed to prevent overheating, but the ASICS may have a slight edge in airflow due to its mesh construction.
Weight and Performance
Weight can play a crucial role in overall performance, especially for competitive runners. While specific weights are not provided, the Brooks Glycerin 21 is designed to be lightweight and responsive, making it suitable for various activities, including road running and cross-training. On the other hand, the ASICS Gel-Kayano 31 offers a balance of cushioning and stability, which may make it feel slightly heavier but more supportive during long distances. The choice between these two may depend on whether a runner prioritizes weight or a supportive structure.
Sales Rank and Popularity
The ASICS Gel-Kayano 31 has a sales rank of 26,176, while the Brooks Glycerin 21 holds a slightly lower rank at 29,881. While both shoes are popular options, the ASICS model appears to be more favored among consumers. This could be indicative of its reputation for quality and performance in the running community. However, it's essential to consider that sales rank can fluctuate based on various factors, including seasonal trends and marketing efforts.
Which should you buy?
Choosing between the ASICS Women's Gel-Kayano 31 Running Shoes and the Brooks Women’s Glycerin 21 Neutral Running Shoe ultimately depends on your personal preferences and running needs. If you prioritize adaptive stability and a higher level of cushioning, the ASICS model may be the better choice, despite its higher price. On the other hand, if you’re looking for a more budget-friendly option with an emphasis on softness and a neutral fit, the Brooks Glycerin 21 stands out as a compelling option. Both shoes offer unique benefits, so consider what features matter most to you before making a decision.
