I have five pair of Chacos, mainly because they have a good arch and are comfortable. They are all different styles and colors - I live in them in spring and summer. I throw them in the washer and they are good to go - the colors stay bright too! I recently ordered a pair of Zongs because I wanted something in brown. Unfortunately, I must return them because they strangle my big toes, no matter how I have adjusted the straps (including extra-loose all over). After a few laps around the house, they are sliding my foot out the back because of the tightening of the toe. It's my opinion that the manufacturers have made the holes too big for the straps, and they don't stay put. Too bad. I plan to look for another Chaco style in brown. Cute as the Zongs are, they're not worth the pain.
