ASICS Gel-Nimbus 25 Running Shoe - Cushioned Long-Run Support

In this review of the ASICS Gel-Nimbus 25 running shoe, the bottom line is simple: this model is best for women who log long miles and want generous, modern cushioning without sacrificing breathability. The shoe's standout is its layered midsole that blends PureGEL for softer landings with FF BLAST ECO PLUS for a responsive toe-off, delivering a comfortable ride on road runs and longer training days. Fit and upper comfort are equally notable thanks to an engineered knit that wraps the foot and improves airflow during extended efforts.

Key Features

• Engineered knit upper: Wraps the foot with a soft feel and improves breathability to help keep feet cooler on long runs.
• High recycled content: At least 75% of the shoe's main upper material uses recycled content, reducing waste and lowering carbon impact.
• Solution-dyed sockliner: Produces the sockliner with much lower water use and reduced carbon emissions for a more sustainable internal finish.
• PureGEL technology: Provides lightweight cushioning that softens ground contact for gentler landings on distance runs.
• FF BLAST ECO PLUS midsole: Delivers a softer landing combined with a responsive toe-off to keep forward motion lively across varied paces.

Who It's For

The Gel-Nimbus 25 is aimed at female runners who prioritize cushioning and comfort for road miles, including daily training runs and weekend long runs where impact protection matters. Runners who appreciate sustainability details in materials and those who value a breathable knit upper will find the shoe especially appealing.

Those seeking a minimalist, ultra-light racing shoe or a trail-specific trainer should look elsewhere; the Nimbus 25 is oriented toward protection and a plush ride rather than minimal weight or off-road traction.

Pros & Cons

Pros

• Generous cushioning from a combined PureGEL and FF BLAST ECO PLUS setup offers comfortable impact protection on long runs.
• Engineered knit upper provides improved breathability and a comfortable wrap around the foot.
• Thoughtful sustainability choices such as high recycled upper content and a solution-dyed sockliner reduce water use and carbon emissions.
