GURU TIP:  Lighter in spite of more cushion and may fit 1/2 size smaller for some. 

TECH TIP:  The super shoe is now even more super. Say hello to the Endorphin Pro 3 that can go fast and far. It is lightweight, incredibly bouncy, and smooth-rolling; setting and breaking marathon records is as easy as easy can be.  Version 3 has a lot more foam and a wider base, making it softer and more stable.  It has the S-shaped carbon plate for propulsion as well as the SpeedRoll technology to quicken transitions. The tough outsole rubber is perfectly placed to protect high wear areas  There are also 3 additional large holes in the tongue for extra ventilation.

BUY THIS SHOE IF... you are a long-distance racer that’s best suited for half to full marathons, especially during summer

DON’T BUY THIS SHOE IF... you have wide feet or you prefer a minimal ride with lots of ground feel
