Saucony Endorphin Pro M 12.5

Born from speed, The Endorphin Pro  was designed to help you step up your race pace, one step at a time. A superior fit and more heel support mean you can keep your eye on the finish line. And with our ultralight PWRRUN PB and a carbon fiber plate, there's no doubt you'll get there faster than ever before.

This is the original colorway for the first edition of the Endorphin Speed. I used this model to run under 2hrs in a half marathon. I ordered a second pair and did not get a chance to use them. They are excellent shoes for running races. Carbon fiber plate.
