I purchased these for my wife.  She works as a waitress and is constantly on her feet.  She is with me now telling me what to type.  This is her fifth pair of shoes she has worn trying to find one that is comfortable.  She loves these.  She has also talked others she works with into buying them and they also love them.  Her only complaint is that they are a little tight in the ankle.

She has since purchased another pair so she can cycle through them while the other one breathes out.
