For fans of Newton running shoes, women’s and men’s best option for trail running is the Boco AT 3. It’s an all-round trail shoe with a flexible sole, while the upper is water resistant to keep your feet dry under the damp, muddy, or slushy conditions that trail runners thrive on. The Boco AT 3 comes with both kind of lugs: the Newton variety for high energy return, and regular old trail lugs for improved traction.
