Built for rugged miles, the NB 610Xv1 pairs a breathable mesh base with sturdy pigskin-suede overlays and molded synthetic reinforcements for structure. A GORE-TEX lining helps keep out wind and moisture while maintaining airflow. The padded tongue and collar add step-in comfort, and reflective hits boost low-light visibility. Underfoot, responsive cushioning and an aggressive trail outsole deliver grip and stability from sidewalk to switchback.
