For race day or kinder gentler terrain they're the equivalent of flats for the off-road runner.

If you're the type who believes lighter is better then look no further than the New Balance Men's MR790 Trail Running Shoe. They don't offer a whole lot of cushioning but in place of that you get a lightweight performance shoe that's ideal for off-road racing. The AT Tread® is low profile for good feel underfoot yet a Rock Stop™ shock distribution plate provides protection when your foot lands on top of a sharp root knob or stone. Consider the New Balance MR790 Trail Running Shoe if you spend most of your time running on relatively flat routes through forest duff grassy fields or would like to reserve a shoe for shaving time on race day.
