I wear flip flops as much of the year as I can, and even when I can't wear them outside, I wear them in the house. I am very happy to have discovered Reef sandals. They are the most comfortable sandals and a reasonable price.

The Seaside sandal has a nice thick sole that provides some arch support and the top is a soft suede. For flip flops, these are stylish and comfortable and the size is true to my shoe size. (If there is any question, go to the next higher size.)

I have a black pair just like this, and that is my dressier pair, while the brown I consider more casual :)
