Light as a feature and so comfortable from the minute I put them on.  Never even knew they were on my feet yet plenty of room and support and very stylish.  I use them at the gym on the eliptical and arc trainer and they provided plenty of cushion and support.  I wear a 9(with a small sock)  and I ordered a 9 and they fit perfect.  Plenty of room in the toe box.  Love these shoes.  I highly recommend them.  I ordered the Black/White with Lime green.
