I fell in love with these when I was in Hawaii a few years ago.  I have worn my brown ones to death and am glad to get them in black.  Great for wet climates like my Florida summers....and soooo comfortable.  I wear a women's 10 and the 10 fits perfectly.  The seller shipped immediately and I received my order much earlier than was predicted.  Plus.....if you kayak or go boating....these float!
