Saucony’s Guide 19 is designed with Pwrrun foam that’s firm yet bouncy, so you can maintain forward momentum. The Saucony Guide 19 is a max-cushioned stability shoe, good for easy and long runs. At first, I was hesitant to try the Guide 19 because it’s a smidge heavier than I prefer. If you have flat or wide feet, Saucony offers wide and extra-wide options so you can have even more room. Bottom line: the Guide 19 is a shoe you can depend on, especially when it comes to the long run.
