For fitness runners who like the variety of running on and off road, the New Balance Women's WR810 Trail Running Shoe is a great all-in-one choice. It's lightweight because it doesn't include the toe protection and underfoot armor that comes standard with many of the models designed specifically for off-road use. However, the AT Tread pattern is aggressive enough for solid traction on muddy or rocky trails yet doesn't feel like you're running on cleats when you hit the pavement. The New Balance WR810 Trail Running Shoe also includes an Abzorb EX heel pad with encapsulated air to provide enhanced cushioning when choosing to train on asphalt instead of forgiving forest duff.
