I FINALLY RAN FAST IN THE SAUCONY ENDORPHIN SPEED 4 - Here's What Happened - welcome back to another video and today, I am sharing with you what happened when I actually took the saucony endorphin speed 4 for a speed workout. It's taken over 100 miles for me to actually put the shoes name to the test and see how they are when you run fast!

What are your thoughts on the saucony endorphin speed 4?
