questionswhat's the difference between mammoth and mammoth…


Besides EVO in the middle? No.


After looking at the EVO's on Croc's website and what I assume is an original pair on Amazon's website, it looks like the difference is in the liner. The EVO in the name is probably just their way of saying they've "evolved" and now have a different liner and differentiates it as the new style.

You can always do "live chat" on Croc's website and ask them. My answer is just a theory.
