Protection and traction from Ndurance

The Ndurance rubber is placed in the high-wear areas of the outsole, and its purpose is to protect the rest of the sole unit from the potentially debilitating effects of surface exposure and abrasion.

The forefoot section of the outsole makes use of blown rubber, which is also used in other New Balance shoes like the NB 990 v4 and NB 860 v9. It is a malleable material that provides traction and protection. Also, its spongy nature adds a bit of responsive cushioning for the foot.

Flex grooves allow the sole unit to be more flexible. Such a design encourages the natural bending capacity of the toe joints, thus energizing the toe-off phase of the gait cycle.

The 840 v4's shock-absorbent midsole

ABZORB is a proprietary cushioning system from New Balance. It is a polymer unit that is derived from foam, and it runs the entire length of the New Balance 840 v4. Its job is to absorb impact shock and transmit the energy to the foot and leg, thereby invigorating the runner to take the next step with ease and sureness.

The top section of the platform has an even surface. This configuration allows the wearer to add custom inserts without worrying about insufficient in-shoe space.

Cloth-like upper coverage

The upper unit of the New Balance 840 v4 utilizes engineered mesh which has a cloth-like disposition. This soft and flexible material allows the foot to flex naturally and be free of irritation. Moreover, its porous façade accommodates airflow into the foot-chamber.

There are thin synthetic overlays that reinforce the upper. These printed add-ons don’t have a lot of weight, and they help in hugging the foot securely.

The padded tongue and collar hug the upper dimensions of the foot. They also mitigate the force of movement that's generated during the run.

An external heel counter with the ‘840 v4’ branding holds the rear portion of the foot in place, preventing it from wobbling or exiting the shoe unintentionally.
