Both are proprietary Saucony foam formulations. PWRRUN+ is a softer variant of the base PWRRUN compound — more compliant underfoot, which means it compresses more on impact and provides a cushier landing. The trade-off is that it is slightly less reactive than PWRRUN — the energy return is comparable, but the initial feel is softer.
| Foam | Shoe |
|---|---|
| PWRRUN | Ride 17, Guide 17, Kinvara 14 |
| PWRRUN+ | Triumph 22 |
| PWRRUN PB | Endorphin Speed 4, Endorphin Pro 4 |
If you have tried the Ride and found it slightly too firm — PWRRUN+ (Triumph) is the upgrade. If you have tried the Ride and found it comfortable — PWRRUN is appropriate. If you want the most responsive foam Saucony makes — PWRRUN PB (Endorphin series).
