## Product: On Cloudmonster Sneakers
**Brand:** On

## Pros
- The On Men's Cloudmonster Void Running Shoes are praised for their excellent quality and reliability.
- Users highlight superior comfort, making them suitable for long daily walks up to 15 km without discomfort.
- The shoes dry quickly and are easy to clean, adding practical convenience.
- Many users say the shoes exceed expectations in performance and quality.
- Highly recommended by several users who rate them a perfect 10/10 for comfort and performance.
- The design supports good foot fit and overall satisfaction with durability, expected to last at least a year with daily use.

## Cons
- The shoes feel significantly harder and firmer compared to previous On Cloudmonster models, which may not suit everyone.
- Some users have reported experiencing knee injuries, calf overload, and foot pain after only a month of use, indicating potential issues with the shoe’s cushioning or support for some runners.
- One customer explicitly mentioned reverting to older On Cloud Monster or even switching brands (Asics) due to discomfort.
- Delivery time has been notably long for some buyers, with reports of waiting up to four months (though this is not related to the product quality itself).
- Customer service was reported as unhelpful in resolving delivery delays, but this does not affect the shoe’s actual performance.

## Bottom Line

The On Men's Cloudmonster Void Running Shoes impress with high-quality materials, comfort, and reliable performance for long walks or runs. However, their firmer sole and cushioning may cause discomfort or injuries for those used to softer shoes, so they might not be the best choice if you have sensitive knees or calves. If that’s a concern, you may want to consider testing older On models or other brands like Asics, known for more forgiving cushioning. Overall, these shoes are great for runners looking for durability and solid support but proceed with caution if you're prone to joint issues.
