5 reasons not to buy

  • The fit slightly suffers for those who have narrow forefoot.
  • Runners who expected more than sufficient flexibility for a well-cushioned shoe were a bit disappointed.
  • The most common knock against the 840 v3 based on online reviews is the poor quality of materials being used.

Bottom line

The New Balance 840 v3 is engineered to provide superior comfort and cushioning for runners who love to pile on the miles. The arch support is good enough for neutral runners to enjoy. It is a running shoe that is every inch patterned after traditional shoes, especially the heel height, heel offset, cushioning, and weight.

  • The 3rd edition of the 840 sees a couple of changes that are all geared towards making cushioning better than ever. In this model, New Balance goes back to the original 12mm heel differential and stacked it with more than adequate midsole foam for superb and almost oversized cushioning. It will make the run more plush and comfortable.
  • Another change is the removal of the N2 cushioning. It has been replaced by the ABZORB foam, which is known for its shock-absorbing features. The new foam is also a bit softer and contributes a great deal to the plush feel with every stride during training sessions.
  • A more flexible mesh is used in the upper to accommodate a wide variety of runners. This upper adapts better to the foot for more comfort and better fit.
  • New Balance also ramped up the flexibility of the 840 v3 by making the forefoot grooves bigger and deeper than the past version. The deeper and bigger grooves are essential in providing flexibility to a heavily-cushioned midsole.

Like the past model, the fit of the 840 v3 is quite full. It has a standard fit that provides just enough space in the heel and spacious forefoot with a secure midfoot. Most runners will find the fit to their liking, especially for numerous hours of training. Available widths are medium, wide, and extra wide. Sizing is on the money with options ranging from 6 to 15 for the men’s and 5 to 12 for the women’s.

The outsole has non-aggressive treads and covered with blown rubber in the most part for better traction. Shielding the high-impact areas is the durable Ndurance rubber for an enduring outsole lifespan. These outsole elements are also present in the New Balance 840 v4.

A full-length EVA provides decent cushioning and durability in the outsole. New Balance made the ride a bit softer by using the ABZORB foam in the shoe. It is a top of the line midsole foam that offers excellent shock-absorbing features and resiliency. Together, they make the cushioning slightly softer, more durable, and with better shock dispersal.

The topmost layer is made of open mesh, which ensures breathability and flexibility. The Phantom Liner supports the mesh panels and improves the structural control of the shoe. The tongue is padded while a Dual Density Collar Foam offers better step- in comfort and helps keep the heel in place.
