Very lightweight and comfortable.  Not the most attractive shoe, but I don't mind due to the comfort.  I wear a 12 and it's a tad short, but ok as long as I don't wear thick socks.  Because the shoe covers most of the top of the foot, they aren't the easiest shoes to get on and off your feet.  I don't mind, but I couldn't recommend them to someone if they had difficulty bending over.
