These are simply incredible! I fell in love with them on a trip to Maui, and now they are almost all I wear (shoe-wise) around the house. I love them so much I now have their sneakers and casual shoes as well.
They run slightly large, so I wear a 10 instead of my normal 10.5. They take a little time to break in since they are leather, but are very comfortable - it is worth it!
I grew up in Arizona and lived in Hawaii for some time, and I have gone through my fair share of sandals (or Slippahs). These are very high quality! I have had them for over a year now and they show absolutely no wear. I wear them practically every weekend day of the year and all summer long (since I have the summer off). They are hands down the most comfortable sandal I have ever worn. In addition, they do not get hot, do not make my feet sweaty, and they do not discolor the bottom of my feet.
The only down side is that they are made from leather (if you have concerns about that).
