Product Information
Full details
The ASICS Gel-Nimbus 23 trainers are designed for adult male runners seeking a balance of high-level cushioning and breathable comfort for daily exercise. These trainers feature advanced shock-absorption technology to provide a supportive ride during long-distance or high-frequency training sessions. While they excel in comfort and impact protection, they are specifically engineered for a neutral gait, which may not suit those requiring high-stability correction for overpronation.

FAQs
Are these shoes suitable for flat feet?
The Gel-Nimbus 23 is designed for neutral runners. If you have flat feet and require significant arch support or stability control, consult a specialist to determine if this model meets your needs.
How often should I replace my Gel-Nimbus 23s?
It is generally recommended to replace running shoes every 300 to 500 miles, as the cushioning properties of the foam will eventually degrade.
Can these be used for gym workouts?
While primarily designed for running, the stable platform makes them acceptable for light gym training. However, they are not intended for heavy weightlifting where a firm, flat sole is preferred.
How do I ensure I get the correct size?
ASICS standard sizing applies; ensure there is a thumb-width of space between your longest toe and the front of the shoe to account for natural expansion during exercise.
Are the insoles removable?
Yes, the insoles are removable, allowing you to insert custom orthotics if necessary.
Troubleshooting
Feeling discomfort after short runs
Ensure the laces are not tied too tightly across the bridge of the foot, which can restrict circulation.
Dirt buildup in the mesh upper
Use a soft brush to gently remove dry dirt. Avoid machine washing, which can damage the structural integrity of the cushioning.
Excessive wear on the outsole
Check your running gait to ensure you are not dragging your feet, which accelerates sole degradation.

Setup, Compatibility & Care
To ensure the longevity of your ASICS Gel-Nimbus 23 trainers, follow these guidelines. Start by ensuring you have the correct fit; as with all performance footwear, allow for a small gap at the toe to account for foot swelling during long runs. For daily maintenance, wipe down the outsole to remove debris and mud after outdoor use. If the shoes become wet, allow them to air dry at room temperature; do not expose them to direct heat sources like heaters or radiators, as this can deform the foam and adhesives. Replace the trainers every 300 to 500 miles, depending on your running intensity and surface type.
