The Saucony Endorphin Speed has been one of the best running shoes on the market ever since the original launched in 2020.

It’s always been one of the most versatile shoes available thanks to its fast, comfortable ride, and I loved the Saucony Endorphin Speed 5 when I racked up over 60 miles in it for my four-star review.

The new Endorphin Speed 6 just launched, and that’s resulted in some great deals cropping up on the Endorphin Speed 5, which is $129 in the Amazon sale right now.

For me that discount makes it the better buy ahead of the new shoe, because although Saucony has made some changes to the Endorphin Speed 6, the overall ride feel is still similar based on my early testing.

The main change made to the Endorphin Speed 6 is that it uses a new midsole foam called PWRRUN PBX, which is meant to be a little lighter and softer than the PWRRUN PB foam on the Endorphin Speed 5.
