Inspired by the legendary Leadville 100 race and built for the ultra-runner, the New Balance Leadville 1210 uses N2 cushioning, a REVlite midsole and a rugged Vibram® outsole to keep runners comfortable while they test their limits. Almost completely void of excess materials, seams, and bulk, the 1210 was designed from the inside-out to prevent skin irritations. With your feet in these shoes, they’ll surely be happy trails.
