Heads will turn when you fly by people in the Saucony ViziPro Endorphin Pro 2. It is your favorite racing shoe supercharged with brighter colors and reflective details for max visibility on the roads. The ViziPro Endorphin Pro 2 is built the same as the Endorphin Pro 2: The ultralight PWRRUNPB has added spring and energy return to have you running your fastest. The signature S-curve carbon-fiber plate combined with the SPEEDROLL technology gives you a powerful transition so you can propel your way to the finish. The speed XT-900 outsole with reinforced high-abrasion zones provides optimal traction so you can take those corners at breakneck speeds. In our review of the Endorphin Pro 2, reviewers loved it for 5K through marathon distances, and even put them through tough speed workouts. For those that feel the need, the need for speed, this is a great shoe for you.
