Who should buy the Saucony Endorphin Speed 3

The third version of the Endorphin Speed is the perfect go-to for runners who: 

  • want a fast tempo shoe
  • needs a versatile trainer (for daily running and uptempo paces) 
  • are looking for a speed trainer that can double as a racing flat

Who should NOT buy it

If you're new to running, you might want to take a look at other running shoes. It might take a while to get used to the Endorphin Speed. 

And for racers who want to run like an elite, it's better to consider the Endorphin Pro 3 instead. 

Endorphin Speed 3 vs. 2: Becoming less like the Pro

There was little to no distinction between the Endorphin Speed 2 and the Endorphin Pro 2. But with the Speed's 3rd edition, Saucony wants to give the shoe its own "personality." 

The brand wants the Endorphin Speed 3 to become a shoe that has more of a daily training feel to it with the same speedy performance. In line with this, here are the implemented changes: 

Same responsiveness, more stability

The Saucony Endorphin Speed 3 is still designed to go fast (thanks to its nylon plate). But this time around, it has more structure for better support and foothold. 

It still has a PWRRUN PB midsole. But it's been made more durable for stable strides. And in the upper, the heel has been reinforced to maximize lockdown. 

In the midfoot, the shoe's plate boasts an S-shaped design (a.k.a winged design) to create a more guided transition.

Gaining weight

For a speed trainer, it may seem like an automatic red flag. But don't worry, it's a negligible weight that serves a great purpose. 

With a more structured upper, the Endorphin Speed goes from 7.8 oz to 8.1 oz (US M 9). 

Less outsole

To offset the weight gain from the upper changes, Saucony has trimmed down the outsole. There's less rubber, but it's still as grippy.
