Upper Design
The ASICS Gel-Nimbus 25 running shoes feature an advanced engineered knit upper that provides a soft, secure fit while enhancing breathability.
The upper is constructed using an innovative knitting process that interlocks yarn strands to create a lightweight, supportive material. Strategically placed knit structures offer zoned stretch and support, conforming to the shape of the foot for a customized, sock-like feel.
The engineered knit upper wraps the foot in soft, breathable comfort. The material contours smoothly with the foot’s shape and movement, reducing irritation and hot spots. Laser cut holes provide ventilation across the top of the foot, allowing heat and moisture to escape. This improves air circulation, keeping feet drier and cooler even during intense running sessions.
The seamless design further reduces skin irritation and friction spots for irritation-free comfort. Runners can fully focus on their workout or race without distractions from discomfort.
Overall, the engineered knit upper provides an ideal balance of softness, breathability, stretch, and support. It enables a smooth, distraction-free run by adapting to each runner’s foot and keeping feet ventilated and comfortable.
Sustainable Materials Reduce Waste
The ASICS Gel-Nimbus 25 running shoe upper features an engineered knit material made with over 75% recycled content. This represents a dramatic reduction in waste compared to shoes made from virgin materials.
Using recycled polyester and nylon content has two major sustainability benefits:
- Reduces landfill waste by giving used materials a second life. The knit upper contains fiber made from recycled plastic bottles, unused manufacturing materials, and worn-out garments. This closes the loop and gives value to items that would otherwise be discarded.
- Lowers carbon emissions versus conventional shoe manufacturing. Producing virgin polyester and nylon is an emissions-intensive process requiring significant energy and crude oil resources. Using recycled materials skips these carbon-heavy steps, reducing the overall emissions footprint of the Nimbus 25 by up to 45%.
The recycled knit upper is a prime example of ASICS’ commitment to responsible production. By innovating new ways to utilize waste materials, the Nimbus 25 running shoe helps lower the environmental impact of our everyday apparel.
Sockliner Technology Reduces Water and Carbon Footprint
The ASICS Gel-Nimbus 25 features an eco-friendly sockliner produced using an innovative solution dyeing process. This process reduces water usage by approximately 33% and carbon emissions by around 45% compared to conventional textile dyeing methods.
The sockliner sits directly underneath the foot, providing cushioning comfort with each step. Using the solution dyeing technique to manufacture the sockliner aligns with ASICS’ commitment to sustainability.
Traditional textile dyeing is highly water-intensive, requiring repeated rinsing and cleaning steps. It also relies on heat to set the dye, which consumes significant energy and leads to greenhouse gas emissions.
In contrast, solution dyeing integrates color pigments directly into the molten raw materials. This allows the color to fully saturate the sockliner fibers with no additional water needed post-production. Lower energy is also used compared to conventional dyeing.
By incorporating the solution dyeing process into the Nimbus 25, ASICS has found an innovative way to reduce the manufacturing footprint while still delivering exceptional comfort underfoot. The advancement provides a prime example of the brand’s dedication to both performance and sustainability.
Midsole Cushioning for Soft Landings and Responsive Propulsion
The ASICS Gel-Nimbus 25 features two key technologies in the midsole designed to provide a smooth, cushioned ride:
PureGELTM Technology
ASICS’ proprietary PureGEL material delivers lightweight, adaptive cushioning in the rearfoot and forefoot to absorb impact. The gel padding deforms upon impact to cushion each stride, then rebounds to its original shape for consistent comfort over miles. This responsive gel system works together with the midsole foam to provide exceptional shock attenuation without sacrificing durability or adding weight.
FF BLASTTM ECO PLUS
Located in the forefoot and heel areas, FF BLAST ECO PLUS cushioning compounds offer plush landings without feeling mushy or unstable. This specially formulated foam incorporates recycled materials to reduce waste while still delivering that “walking on clouds” feeling underfoot. The foam compressses on impact for a soft touchdown, then springs back to propel your next stride with a responsive toe-off. FF BLAST ECO PLUS gives you the best of both worlds – pillowy soft comfort and snappy energy return.
Durable Outsole for Traction and Grip
The outsole of the ASICS Women’s Gel-Nimbus 25 is designed for durability, traction, and grip. It features a high abrasion rubber compound that provides lasting wear and tear resistance, even when running on rough surfaces.
Strategically placed rubber lugs offer excellent multi-directional traction to keep you steady on your feet on a variety of terrains. The lugs are angled and shaped to provide traction when pushing off, changing direction, and braking. This makes the Gel-Nimbus 25 suitable for both road running and tackling dirt trails.
The outsole rubber also supplies plenty of grip. The tread pattern helps to grip the ground while the rubber compound sticks to surfaces to prevent slipping. Runners will feel confident striding on wet roads, slick track surfaces, loose dirt, and more without slipping.
The durable high abrasion rubber outsole equips the Gel-Nimbus 25 with traction and grip for training and racing on varied surfaces. Runners can count on lasting mileage and stability from this key component of the shoe’s construction.
Lightweight Performance
The ASICS Gel-Nimbus 25 women’s running shoes are designed for lightweight performance without sacrificing cushioning or support. The shoes weigh approximately 9.7oz for a women’s size 8.
This puts the Gel-Nimbus 25 at the lighter end of the spectrum compared to similar premium cushioned trainers. For example, the Brooks Glycerin 18 weighs 10.2oz and the New Balance 1080v11 weighs 9.5oz in the same size 8. The nimble weight makes the Gel-Nimbus 25 ideal for logging daily miles or long endurance runs.
The lightweight build is achieved through ASICS use of breathable mesh uppers, no-sew overlays, and midsole materials like FlyteFoam and Gel cushioning which provide bounce and responsiveness without added bulk. Runners can enjoy soft landings and smooth transitions in a shoe that feels fast and natural.
Fit
The Gel-Nimbus 25 running shoes have a snug yet comfortable fit ideal for neutral runners with medium to wide feet. ASICS designed the upper with an engineered knit material that provides a soft, flexible feel that moves with your foot.
The knit upper wraps the foot securely without uncomfortable pressure points. Reviewers note that the Gel-Nimbus 25 runs true to size. If you normally wear a size 8.5 womens, then staying with that size should give a great fit.
The Gel-Nimbus series consistently ranks as a top option for runners who prefer a more spacious toe box. So if you have wider feet or swelling concerns, then the Nimbus 25 can comfortably accommodate without squeezing the toes. The lace-up closure also enables cinching a secure midfoot lockdown.
Overall, the Nimbus 25 provides an ideal fit for medium to wide foot types. The knit upper and lace-up closure enable customizing a comfortable, breathable, and supportive fit during runs.
Performance

Together, these technologies offer the right blend of softness and responsiveness for a dynamic ride. Testers have praised the plush cushioning and smooth toe-off of the Gel-Nimbus 25.
Durability and Traction
The outsole uses ASICS High Abrasion Rubber (AHAR) strategically placed in high-wear areas for enhanced durability. Flex grooves allow the shoe to flex naturally with the foot for a smooth stride. The outsole tread incorporates thick horizontal and vertical grooves to provide excellent multi-directional traction on varied surfaces. Reviewers have noted the impressive durability and traction of the outsole even after high mileage.
