Summary

We spent 8 hours reading reviews from experts and users. In summary, this is what runners think:

9 reasons to buy

  • Despite the minimal padding, most runners found the comfort of the Motion IV in the soft interior and wraparound fit.
  • Some mentioned that the durability is well worth its hefty price.
  • A good number of runners have used the 4th version of the Motion for long-distance training or for speed sessions.
  • It is light.
  • The shoe has a noticeable softness and flexibility despite being a designed for mild to moderate overpronators, as observed by several runners.
  • A new foam in the arch enhances medial support.
  • The new engineered mesh has bigger holes for better breathability.
  • 360° of reflectivity.
  • Quite a number of runners who are transitioning to midfoot or forefoot striking find it easier to do so in this shoe.

3 reasons not to buy

  • It is a very expensive shoe.
  • A significant number of reviews mentioned how the tongue crumples or bunches.
  • A couple mentioned that it does not feel as plush because of the flat tongue.

Bottom line

The Newton Motion IV is quite a find as it is lightweight for a stability trainer. Because it is quite light, it can double as a tempo merchant or as a high-mileage companion. The arch support is very effective without being jarring while the 5-lug system continues to deliver a uniquely responsive experience.

Updates to Newton Motion IV

  • The upper is where Newton focused the changes in the Motion IV. In this version, it sports a new engineered mesh that has bigger holes for enhanced breathability. The mesh also has a fantastic hold on the foot and really helps with the overall stability of the shoe.
  • The overlays have been re-arranged as well to improve the fit of the Motion IV. There is better midfoot hold as the stitched overlays are focused right around the section where the midfoot meets the forefoot. Some of the welded overlays are stretched from the midfoot to the heel.
  • Speaking of the heel, it gets better locked down feel as it gets extended help from the welded overlays coming from the midfoot.
  • Lastly, and probably the most divisive change is the removal of basically all padding in the tongue. It is now a flat tongue, albeit made of soft material. Newton wants to tongue to feel like a second skin in this model.

Newton Motion IV size and fit

Here, Newton maintains the trademark Motion fit. It has decent security in the heel and the midfoot while the forefoot has very good space for the toes to wiggle. Naturally, the fit can be taken advantage of by those with slightly narrow to slightly wider feet. Sizing is also a little different as it is about ½ smaller than the previous model.


Outsole

Super High Abrasion Rubber Compound or SHARC covers the underfoot of the Motion IV. It is very durable and has very good traction. The most notable feature in the outsole is the 5-lug system or what Newton calls as POP 1. In this rendition of the POP, the edges of the lugs are even or squared and gives the most responsive feel relative to the POP design among Newton shoes. As the runner lands, the lugs compress to form a trampoline effect.


Midsole

The staple of Newton shoes is a High-Rebound EVA, which is compression-molded. Adding stability to the shoe is the new EMB or Extended Medial Bridge. This is Newtonian talk for a wedge of stiff EVA on the medial side to hold off overpronation. The force upon impact when landing is transformed into responsive energy through the outsole lugs and midsole. Hence, Newton calls this as the Action/Reaction Technology.


Upper

The no-frills upper is largely made of the new engineered mesh that greatly helps the ventilation of the 4th version of the Motion because of the moderately large holes. Helping to hold the foot and deliver a nice fit is the combination of stitched and welded overlays. The interior of the shoe is lined with very soft fabric while a flat tongue adequately keeps pressure off from the laces.
