New Balance 57/40 is a model of running shoe offered by the American shoe company New Balance. The "57/40" refers to the shoe's midsole construction, which combines a 57-degree heel and a 40-degree forefoot for a more natural and responsive ride. The shoe is designed for runners who are looking for a balance of cushioning and stability, and it is built on the company's REVlite midsole platform for a lightweight, responsive feel. Some of the features of the shoe may vary depending on the edition and version of the shoe.
