These are my DG shoe of preference. I have four pairs. One wore out after a year, a second I use when it's wet or muddy out, a third I just put in the rotation, and I have a fourth on reserve. I was a little patient, and I scored two pairs off of Adidas's website for $70 shipped. They do pretty well on all surfaces, concrete included. They are almost like baseball cleats whereas they may collect some mud in them, and you have to bang it off on tee pads, sometimes. Very comfortable, very, very lightweight.
As far as waterproof, no they are not. But, for the price, the materials dry out very quickly, another good feature of trail running shoes.
