Price Comparison

When it comes to price, the Under Armour Women's Charged Surge 4 is significantly more affordable at $51.95, while the Brooks Women’s Glycerin 23 Neutral Running Shoe is priced at $159.99. This makes the Under Armour shoe about 67% cheaper than the Brooks model. The substantial price difference may attract budget-conscious runners who are looking for a quality running shoe without breaking the bank. However, the higher price of the Brooks shoe reflects its premium features and specialized design aimed at neutral runners.

Comfort and Cushioning

The Brooks Women’s Glycerin 23 is designed for premium comfort with its upgraded nitrogen-infused DNA TUNED midsole, which provides an enhanced cushioning experience. This shoe boasts an 8mm offset and is known for its plush cushioning, making it ideal for long runs and daily training. In contrast, the Under Armour Women's Charged Surge 4 features Charged Cushioning, which also provides comfort and responsiveness. While both shoes are neutral, the Brooks offers an additional 2mm of cushioning in the forefoot, catering specifically to runners seeking a softer landing.

Upper Construction

In terms of upper construction, the Brooks Women’s Glycerin 23 features a triple jacquard warp-knit upper that wraps the foot securely while allowing for breathability. This design aids in reducing hot spots during extended wear, which is especially beneficial for long-distance runners. The Under Armour Women's Charged Surge 4, on the other hand, has a breathable mesh upper with synthetic overlays for added support. While both shoes are designed to be breathable, the Brooks shoe’s engineered upper may provide a more customized fit on longer runs.

Weight and Flexibility

The Under Armour Women’s Charged Surge 4 weighs 10.05 oz, which may appeal to runners who prioritize a lightweight shoe for speed. On the other hand, the Brooks Women’s Glycerin 23 does not specify its weight, but its focus on cushioning and comfort may inherently make it a bit heavier. The Under Armour shoe is designed to offer a balance of flexibility and cushioning, which is crucial for those who want a versatile running experience. However, runners looking for a shoe that excels in plush comfort might prefer the Brooks model despite potential weight differences.

Stability and Support

The Brooks Women’s Glycerin 23 emphasizes stability with its wide platform and strategic midsole sculpting that promotes balanced movement. This is particularly advantageous for runners who need consistent performance over longer distances. The Under Armour Women's Charged Surge 4 provides enhanced cushioning around the ankle collar, contributing to overall comfort and support. While both shoes cater to neutral runners, the Brooks model may offer more stability for those who engage in high-mileage training.

Durability and Longevity

When it comes to durability, both shoes are designed for longevity but focus on different aspects. The Brooks Women’s Glycerin 23 is built to handle high-mileage comfort, making it a solid choice for daily training. Its premium midsole package suggests a focus on long-term performance. Meanwhile, the Under Armour Women's Charged Surge 4 features a durable rubber outsole designed for traction and flexibility, making it suitable for various terrains. While both shoes are durable, the Brooks may be better suited for runners who prioritize long-distance durability.

Style and Aesthetics

In terms of style, the Brooks Women’s Glycerin 23 comes in an eye-catching White/Phantom/Cyber Pink color scheme, appealing to those who enjoy a fashionable look while running. The Under Armour Women's Charged Surge 4 offers a clean design in White/Distant Gray/Metallic Silver, which is versatile but may not stand out as much. While both shoes have appealing aesthetics, the choice may come down to personal preference in color and design.

Which should you buy?

Choosing between the Brooks Women’s Glycerin 23 and the Under Armour Women's Charged Surge 4 ultimately depends on your running needs and budget. If you prioritize premium comfort, plush cushioning, and stability for long-distance runs, the Brooks model is worth the investment at $159.99. However, if you're looking for a budget-friendly option that still offers decent comfort and flexibility at $51.95, the Under Armour shoe is a solid choice. Consider your running habits, budget, and personal style preferences when making your decision.
