Updates to New Balance Minimus 40 Trainer

  • The New Balance Minimus 40 Trainer is a minimalist workout shoe that was crafted to suit the various needs of cross-training aficionados. It features a woven synthetic mesh upper to keep the foot ventilated during vigorous exercises. The synthetic rubber reinforcements and an external TPU heel clip give structure to the façade and support the foot throughout the movement.
  • This shoe is marketed as the most run-friendly Minimus training shoe due to the minimal, yet responsive cushioning. It is delivered through the proprietary Rapid Rebound foam, as well as the REVlite compound in the heel.
  • A 4 mm heel-to-toe differential offers a relatively flat disposition. It helps in keeping the foot stable during lifts and lateral movements. A low-profile construction offers a more sensitive ground contact.
  • The trainer employs the Vibram® rubber outsole for multidirectional traction and enhanced durability.

New Balance Minimus 40 Trainer size and fit

The New Balance Minimus 40 Trainer is offered in both men and women’s versions. Lengthwise, it follows standard training shoe measurements. A range of full and half sizes is available from 7 to 15 for men and 5 to 12 for women. The width profiles are standard and wide: gentlemen can choose between D – Medium and 2E – Wide, and ladies can take a pick between B – Medium and D – Wide. The shoe is meant to be close-fitting.


The Minimus 40 Trainer utilizes a Vibram® rubber outsole to provide athletes with boosted multi-directional traction and protection against abrasion. The sole extends to the lateral and medial sides for added lateral stability and security.

The geometrical flex grooves throughout the unit make sure that the natural flexibility of the foot is not hindered.


The New Balance Minimus 40 Trainer uses the Rapid Rebound foam for a cushioned and responsive ride. It is claimed to give more energy return than the standard foam.

The REVlite technology features a foam compound for extra shock absorption in the heel section. The material is 30% lighter than other New Balance foams, but it offers the same responsiveness and durability.


The upper unit is made up of a woven synthetic mesh to provide a lightweight and breathable coverage. It is also designed to be flexible, bending along with the foot without creating any pressure points.

The shoe is reinforced with synthetic rubber overlays for more structured support and protection against wear and tear.

A molded external heel cup is made of a lightweight and sturdy TPU material to hold the rear firmly in place throughout the training session.
