Welcome back to Sole Stats Unboxed! We’ve got another shoe from Saucony today, so let’s see what it is: the new Saucony Endorphin Speed 6.
This shoe remains a neutrally cushioned, nylon-plated daily trainer that’s going to be great for everything. You can race in it, workout in it, and still recover in it — especially now that Saucony has added two more millimeters of foam to the midsole, bringing the stack height to 30mm in the forefoot and 38mm in the heel.
Stack Height and Weight
The shoe retains its 8mm drop, which it has had since version one. And even with more cushion underfoot, it remains impressively light at 6.9oz in the women’s and 8.2oz in the men’s.
The Upper
Comparing the uppers of version five and version six, you’ll immediately notice a couple of key differences. First, the upper is much lighter and much more breathable, and it feels incredible. That carries through to the comfort and lockdown you get through the heel collar, along with a lengthened tongue that sits over your foot much more nicely — a much-needed change from version five.
The Midsole
As mentioned, the Endorphin Speed 6 packs two more millimeters of foam throughout the midsole compared to version five. But you really don’t notice that added stack height, because Saucony is using their new PWRRUN PBX, designed to be more efficient while being lighter than PWRRUN PB — and it’s something you notice immediately underfoot.
The Outsole
Here’s a quick comparison of the outsoles from version five to version six. The nylon plate is still on display, but less of it is exposed this time around, helping prevent debris from getting trapped underneath. Saucony has also slightly remapped the amount of rubber on the heel, while leaving plenty in the mid and forefoot.
Final Thoughts
Another massive thank-you goes out to our friends at Saucony for allowing us to unveil this shoe early for all of you. I’m personally incredibly excited to take this shoe out for real — especially on the track for some tempo efforts.
This was definitely an update worth waiting for.
The Saucony Endorphin Speed 6 will be available at all Charm City Run locations starting October 15th for $175, and it’s worth every penny.
