Lightest pair of shoes I've ever put on my feet.  Love the breathable fabric as well.  I don't know what it is about Reebok shoes for me, though.  The arch was slightly off for me to feel totally comfortable.  That, I think, is not a flaw of the company or the shoe, it is well designed, just not designed for everyone.  I decided to return these as well.  I recommend trying them on in a store first, if you can.
