Love my Keen Milo II's. Have a thread over at DGCR that has a more in depth review, So I'll just go over the key points...
Durability - A lot of people rag on the durability of these shoes, I've had mine since January and played 100's of rounds since then, They have some wear and tear but nothing that I would attribute to poor quality control like someone else said earlier in the thread.
Waterproof - Certainly not as waterproof as a pair of rubber rain boots, or even Goretex, but trudging through puddles or dewey fields my socks have always kept dry. Even worn them in about ankle high water my feet would've stayed dry except for the water was higher than the shoe.
Comfort - They are a really snug fitting shoe and provide crazy good ankle, foot, and arch support. They did start out a little stiff, but what new athletic shoes don't
Long story short is I'm very happy with my Milo II's they certainly didn't shave any strokes off my game but keep my feet happy!
