We've tested these running shoes to expand our database and allow users to compare results to help with their buying decisions. We don't expect to write a full review, but if you have any questions about this product, please let us know.
We buy and test running shoes with a very data-oriented approach. While we're just getting started, our methodology already has dozens of tests to help you make the right purchasing decision for your needs. Not only do we use high-end equipment to gather objective data, but we also order multiple sizes of the same shoes so team members can log in miles. This real-world testing is conducted at various paces and conditions, across different types of workouts, to cover all the bases. This allows us to verify our results and ensure they align with what you might feel with a specific pair.

The Saucony Guide 19 builds on the same formula as the Saucony Guide 18, but with more cushioning, a broader arch platform, and a more responsive ride. Both deliver excellent stability, but the newer model is more protective underfoot. The Guide 18 remains a dependable support shoe at a lower price, while the Guide 19 is the better pick for runners who want a bit more protection.
The On Cloudrunner 3 and Saucony Guide 18 are two support trainers, but they approach their role quite differently. The Saucony uses a much wider platform, which makes it feel more substantial underfoot, even though it is slightly lighter. Its midsole is also a bit more cushioned, which adds protection without sacrificing control, resulting in a more stable and more complete ride overall. The On relies more on a structured heel clip and raised sidewalls, with a firmer, more rearfoot-focused approach to guidance that feels less forgiving and less well-rounded.
