They have produced numerous sports shoes and lifestyle shoes, including running shoes, and are loved by a wide range of generations worldwide. From New Balance, the "CM878," a heritage running shoe released in 2000 for long-distance runners, is now available in new colors. Incorporating the sole technology used in the flagship model "M1700" released in 1999, the midsole features "ABZORB," a cushioning material with rebound elasticity, providing exceptional cushioning and comfort.
