Get ready to tackle the rough and tumble with the new Nike Juniper Trail 2. The upper mixes synthetic leather, mesh and fabric for a breathable, rugged finish. Ties integrate the lacing system for a more secure fit, and the sole is made of at least 8% Nike Grind, a tough material made from shoe production waste. The rubber tread is the element that makes the difference, as its tapered tread blocks provide superior grip and traction even when climbing.
