I had surgery for my severe plantar faciitis about a year ago, and while it is significantly better, regular flip flops just don't offer enough support to keep me pain free. I bought these hoping I could wear them without pain and I am thrilled to say they are perfect. The arch support is excellent and the soles are cushy. The strap doesn't cut into my toes or foot at all, they are truly the most comfortable flip flops I have ever owned, and more comfortable  than almost any other shoes in my closet. I am so pleased with this purchase and I'm sure you will be, too!
