Although other reviewers mentioned it, I went ahead and purchased and indeed, these Tevas turned the bottoms of my feet black.  I'm not talking a little black; a lot.  Worst yet, the black did not come off with scrubbing.  It had to wear off in a matter of days.  It's really unattractive to wear sandals with black feet.  Additionally, while these shoes were a comfortable fit, they are not as attractive as I had hoped.  They pretty much look like Tevas sport sandals on high risers.  Definitely not worth the $.  For my money, the Teva Ventura Wedge Modac was a superior product.  Sent these shoes back immediately.  Easy return and refund with Amazon. Yay!
