I've got a pair of the Puma Brutale boots.

Unfortunately there is only one distributor in Australia, and one retailer in my city so I was raped on the price. That being said however they are great boots; very comfortable, stable and look a great deal better than the other options. My only criticism is that if you don't have fairly wide calves, you'll find the Velcro top will stick out, and can get caught on things (such as pegs and stands)
If you want something that looks normal under your pants, these are the go.
