Asphalt running brings a specific set of challenges. When running on the trail, you never know what you might encounter. New Balance’s Fresh Foam Heirro Trail runners are made to tackle it all. Their one-piece, full-length Fresh Foam midsole provides a cushy yet natural ride, while the TPU-coated textile upper is both breathable and made to keep splashes from soaking your feet. The bootie-like, toe-protecting upper rides atop a MegaGrip outsole from Vibram that’s built to maximize surface contact and traction in any direction, making them as well suited to straight runs of dirt as they are to climbing over wet rocks.
