I was amazed by how light weight these shoes are when I first picked them up out of the box.  They are without a doubt the lightest men's athletic shoe that I've ever seen.  The shoe looks great.  It's sleek with just enough color to make it stand out without being too flashy.  The soles are extremely flexible and cushy which makes them perfect for running but they are cross trainers so good for many other activities.  As far as sizing, they seem to run a little bit large so you might want to go 1/2 size down from what you normally wear in a running shoe.  My son usually wears an 11 1/2 and he can wear these but does have to use fairly thick socks to keep them from slipping.
Overall, a really nice looking and well performing shoe for a decent price. What's not to love?
