This price difference could be significant for budget-conscious buyers seeking quality running footwear. Both shoes are highly rated, with ALTRA holding a sales rank of 23,294 and Brooks at 29,881, indicating a strong presence in the market. If you're looking for a lower initial investment without sacrificing performance, the ALTRA option may be the way to go.

Comfort and Cushioning

In terms of comfort, both shoes prioritize cushioning, but with different approaches. The ALTRA Women's FWD VIA features Altra EGO FLO supercritical midsole foam, designed to provide a lightweight and soft underfoot feel. On the other hand, the Brooks Glycerin 21 shines with its nitrogen-infused DNA Loft v3 cushioning, which is optimized for maximum softness and is touted as the ultimate in plush comfort. While both shoes have received the APMA Seal of Acceptance, the Brooks model may appeal more to runners who prioritize extreme softness over other features.

Fit and Design

When it comes to fit and design, the Brooks Women’s Glycerin 21 offers a plush internal fit with an engineered warp knit upper that is both breathable and flexible. This design allows the shoe to expand comfortably with your stride. Conversely, the ALTRA Women’s FWD VIA is designed with a rocker shape that promotes a natural gait and efficient toe-off. While the ALTRA focuses on a natural running experience, the Brooks prioritizes a soft, accommodating fit, which may be preferable for those who favor a snug, yet cushioned feel during their runs.

Support and Stability

Support is another crucial factor in running shoes. The Brooks Glycerin 21 provides neutral support along with soft, stable transitions, making it suitable for various types of running. Its broad platform stabilizes the foot, promoting smooth heel-to-toe transitions. In contrast, the ALTRA Women’s FWD VIA emphasizes a natural stride without compromising comfort. While both shoes offer commendable support, the Brooks model may be the better choice for runners who require a more structured support system.

Durability

Durability is essential for any running shoe, and both models are built to endure. The Brooks Glycerin 21 features a lightweight, responsive construction that supports durability while maintaining plush comfort. The ALTRA Women’s FWD VIA, with its supercritical midsole foam, is designed for a soft feel yet remains durable enough for regular use. Although both brands are known for quality, Brooks may have a slight edge with its emphasis on long-lasting cushioning technology.

Versatility

When considering versatility, the Brooks Women’s Glycerin 21 is ideal for various activities such as road running, cross-training, and gym workouts, thanks to its neutral support and maximum cushioning. Meanwhile, the ALTRA Women’s FWD VIA, while primarily designed for road running, offers features that could also benefit casual runners or those who favor a more natural running experience. If you seek a shoe that can handle different types of training, the Brooks may be the more versatile option.

User Experience

Both shoes have garnered positive feedback from users, but their distinct features cater to different preferences. The ALTRA Women’s FWD VIA is favored for its lightweight feel and natural stride enhancement, ideal for runners who appreciate a more minimalist approach. Conversely, the Brooks Glycerin 21 is celebrated for its plush comfort and soft fit, which many users find perfect for longer runs. Depending on your running style and personal preferences, you may find one shoe resonates more with your experience than the other.

Which should you buy?

Ultimately, deciding between the ALTRA Women’s FWD VIA Road Running Shoe and the Brooks Women’s Glycerin 21 comes down to your personal running needs and budget. The ALTRA shoe is about 17% cheaper and focuses on promoting good foot health with its natural stride design, making it suitable for those who prefer a lighter, more streamlined shoe. The Brooks model, while more expensive, offers unparalleled softness and versatile performance across various activities. If comfort and cushioning are your top priorities, the Brooks may be the right choice. However, for a more budget-friendly option that still delivers quality, the ALTRA is a strong contender.
