I discovered Magnum boots a few years ago and love them.

They were designed for police so all day comfort is key.

I think they're light. I wear them year round-Utah. Have great self cleaning treads. About $60. Have a variety of styles including ankle cut, 4" and 8" boots.

If you get the right design, they will look like dress shoes with pants.

I've also heard good things from the Converse line of boots.
