Looking for a dynamic shoe but torn between a model for high-intensity sessions and a versatile everyday pair? The Saucony Endorphin Speed 6 and ASICS Novablast 6 offer two compelling options.
Try the Speed 6 first if you’re looking for a pair for your speed workouts. Start with the Novablast 6 if you want to cover most of your runs with a single shoe. This advice is based on their construction; your own comfort may lead you to prefer the other option later.
A key difference: the plate
The Speed 6 combines PWRRUN PBX foam, a nylon plate, and SPEEDROLL geometry. Published reviews describe a design geared toward sustained efforts, with a relatively stiff and responsive sole.
The Novablast 6 combines FF BLAST MAX foam with an FF TURBO SQUARED element in the forefoot, without a propulsion plate. ASICS adds ASICSGRIP rubber to the front of the outsole.
| Criteria | Endorphin Speed 6 | Novablast 6 |
|---|---|---|
| Foam | PWRRUN PBX | FF BLAST MAX and FF TURBO SQUARED element |
| Plate | Nylon | No propulsion plate |
| Key construction | SPEEDROLL | Responsive forefoot element |
| Recommended use | Sustained sessions and long fast stretches | Varied daily training |
Which one for a single pair?
Look at your week before choosing. If easy runs make up the bulk of your mileage, try the Novablast 6 at that pace. A primary pair needs to remain comfortable during regular sessions, not just when you pick up the pace.
The Speed 6 can also work for some runners for several types of runs. However, its plate and transition require a careful test at low intensity: do you enjoy that feeling during twenty or forty minutes of easy running?
Which one for your tempo sessions?
For sustained blocks or long stretches at race pace, the Speed 6 is a logical candidate. Test its transition at your target pace and ensure the shoe allows you to run without feeling restricted.
The Novablast 6 is still worth considering if you prefer a design without a plate. It can be a consistent choice when you want to vary paces without increasing your number of pairs.
For example: if you already own a comfortable shoe for easy runs and are looking for a second pair for targeted sessions, start with the Speed. If you are replacing your only shoe, start with the Novablast, then compare.
Our verdict
The Speed 6 deserves your attention if you want to dedicate a clear space to high-intensity training in your rotation. The Novablast 6 is an option for broader daily use. Your decision should follow your current schedule and your preference for underfoot feel.
