ASICS Men's Gel Nimbus 25 Running Shoe - Cushioned Road Trainer

In this review of the ASICS Men's Gel Nimbus 25 running shoe, the bottom line is simple: this is a maximum-cushion neutral road trainer built for runners who prioritize soft landings and long-run durability. The shoe combines new PureGEL inserts with FF BLAST ECO PLUS foam and an engineered knit upper to deliver a plush, responsive ride that still feels stable. For runners who log long miles or want a comfortable daily trainer for both running and walking, the Nimbus 25 stands out for its cushioning and thoughtful materials.

Key Features

• Engineered knit upper: Wraps the foot with a soft, breathable fit that makes step-in easier and adapts to motion without feeling restrictive.
• Recycled upper content: At least 75% of the main upper material is recycled, reducing waste and lowering the shoe's environmental impact.
• Solution-dyed sockliner: The dyeing method cuts water use by about 33% and reduces carbon emissions by about 45% compared to conventional dyeing.
• PureGEL technology: Provides enhanced shock absorption for noticeably softer landings and smoother transitions between gait phases.
• FF BLAST ECO PLUS cushioning: Offers a lighter, more energetic foam with increased underfoot volume for a plusher ride and a responsive toe-off.

Who It's For

The Nimbus 25 is best for neutral runners who cover moderate to high weekly mileage and want a plush, protective platform for long runs or recovery days. Its generous cushioning and stable ride also make it a good choice for walkers or runners returning from minor soreness who need extra shock attenuation.

Less appropriate for runners who need maximal control for severe overpronation or for speedwork specialists seeking a minimal, lightweight race flat; those buyers should look to shoes with firmer, lower-profile midsoles or dedicated stability platforms.

Pros & Cons

Pros

• Excellent cushioning and softer-than-ever landings thanks to PureGEL and FF BLAST ECO PLUS foam.
• Comfortable, adaptive engineered knit upper with an easier step-in thanks to the knit tongue and collar design.
• Durable construction praised by users for long-run longevity and an ample toe box for comfort.
• Material choices reduce water use and carbon emissions, reflecting a greener manufacturing approach.

Cons

• With a maximum cushioning focus and 10 mm heel drop, it is heavier than minimal trainers and not ideal for fast race efforts.
• The plush ride may feel too soft for runners who prefer a firmer, more propulsive underfoot feel.
