Let me start of by saying, I hate traditional mountain bike shoes. They feel like soccer cleats, squeezing my very flat foot to the point of beyond annoying to painful. There. Said it. Now, if you grew up with Mid 90s high tops, you will be in love. Great feel in the cuff with good ankle support. Rubber grips well with DH flats, but I currently have the cleat in and use them every day all mountain. They can get a bit hot, my feet were really sweating when we were biking in Virgin, Utah, but then again, everything sweats when I am riding.
Be sure to read the instructions before cutting out the rubber sole to install the cleats. It is worth paying attention to. My slash and tear method worked fine, but could have gone better.
