This is my third pair of Acorn's Spa thong sandals.  Two were gifts for others and one was for me. I've purchased other styles of Acorn houseshoes, but prefer this style for looks, wearing and comfort, especially on tile floors.  They are really smart looking on.  Fit is right on size, too.  They also look like new after being washed in the washing machine. I wear a 7.5 shoe and the medium size fits perfectly. I'm sure I will be buying many more Acorn shoes!
