SummaryThe New Balance MX40v1, also known as the New Balance Minimus 40, is designed for CrossFit, HIIT, short runs, and weightlifting. The shoe is low-profile, has a stable feel, lightweight, and a grippy outsole. Some have found it too narrow in the forefoot, but New Balance does offer wide sizes so that is something to keep in mind. The shoe offers a good balance between stability for power and softness for cushioning.
The midsole in the Minimus 40 features Rapid Rebound foam. The foam offers cushioning and responsiveness while providing more energy than standard New Balance foam. In the heel, you will find REVlite technology for shock absorption. This is 30 percent lighter than other New Balance foams but with the same durability and responsiveness that New Balance is known for.
On the outsole, the shoe has Vibram rubber for traction and flex grooves to aid in the natural flexibility of your foot. The sole extends from the medial and lateral sides for added stability while Cross Training. The upper is made of synthetic mesh, which is lightweight and durable. Synthetic overlays offer more support and protect the shoe — as well as your feet — from wear and tear during workouts. The external heel cup is made with TPU material for added stability. Because of its design, the shoe can be worn with or without socks depending on your preference.
