Updates to Newton Gravity IV

  • Minor and few updates are unveiled in the 4th edition of the Gravity. First clear change is the new mesh that has bigger holes for immediate improvement in shoe breathability. The second change that is most significant in the upper the relocation of the overlays. Newton concentrated the overlays in the area where the midfoot meets the forefoot. This really gives a nice hold in this section.

Newton Gravity IV size and fit

The fit is through and through a trademark of the Gravity line. Newton continues to provide a snug fit in the heel to the forefoot in this shoe. There is also enough room in the forefoot for a comfortable ride, even as the distance piles up. Runners with narrow to medium feet are built for this kind of fit.


Outsole

The outsole is truly Newton unique. It has the SHARC or a very durable carbon rubber that also includes excellent traction. However, the outsole is very prominent because of the 5-lug system. For the Gravity IV, Newton uses the POP or lugs that have squared borders for a more aggressive response to impact. Upon landing, the lugs depress inside a cavity and then pops back for that bounce back feel.


Midsole

Newton designed the midsole to work in tandem with the 5-lug system of the outsole. As basic cushioning features go, there is a full-length and compression molded EVA. This helps with the transition from landing to take-off. The lugs in the outsole perform a trampoline effect where the same force of impact is returned. Newton calls this the Action/Reaction technology.


Upper

A very minimal upper greets runners in the form of an airy mesh that guarantees breathability. New overlays in the midfoot/forefoot area holds the foot really well. There is minimal padding in the collar while the tongue is almost flat. Newton offers 360° of reflectivity in this shoe.
