I believe Mephisto makes the best shoe. However, the SANO Raptor was a disappointment. It was supposedly designed after some barefooted tribe that walked in the sand which was best for the human foot. After wearing these shoes for a few months in NYC and climbing up and down subway stairs my feet, legs, and hips developed severe pain. I started to waddle and thought it was age creeping up on me. I changed shoes and thought I was in heaven. I threw these SANO shoes in the garbage since I couldn't find a Neanderthal to give them to and wasn't cruel enough to donate them to some unsuspecting recipient.
