Newton Gravity Review


The Look

The first thing to notice about the new Newton Gravity is that it is now available in colors that you will want to wear. Though color is not the most important aspect of a shoe, it is certainly the first thing to get noticed. That being said, I love the green-on-black look of the newest line.

The Fit

The fit of the Newton Gravity is right on. Unlike the Newton MV2 the toe box is roomy and accommodating without letting the foot move around. These shoes fit wonderfully right out of the box and continued to remain comfortable until they were retired at 350 miles.

The Upper

The upper is a stylish and durable. with extra reinforcement in all the critical places. In particular I appreciate the additional stitching reinforcing the toe baox. I know I am not the only runner to have shoes have a blow out around the toes, and did I mention, now Newtons are available in colors you will want to wear.

The Weight

Weighing in at just over 9 ounces, the Newton Gravity is one of the heavier shoes I have reviewed.  Compared to the average running shoe it is on the lighter side, but compared to the Newton MV2 (about 6 ounces), the Newton Gravity is a beast, but this weight difference did not seem to slow me down, and the Newton Gravity Trainer lasted twice as many running miles as the Newton MV2 before critical fail.

The Outsole

The outsole features the classic Newton four lugs under the forefoot. These lugs raise the forefoot and provide comfort and protection under the forefoot where the foot of the natural runner will first contact the ground. Directly beneath each lug is a corresponding cutout in the midsole, this is what Newton has patented as their “Action-Reaction Technology,” designed to return a small amount of energy with each stride. I am still unsure of my feelings on this Newton gimmick. I feel the best shoes are free of gimmicks, but the Newton gimmick is a gimmick in the right direction, encouraging a forefoot stride, rather than most previous gimmicks which were designed to make heel striking more comfortable.

The Differential

The Newton Gravity has a 3mm differential. This is less than most running shoes, however, as the champions of “natural running,” I do wish that Newton would take a step forward and join Altra in dedicating to only making zero-drop shoes. Currently the only zero drop shoe sold by Newton is the MV2.

The Durability

From the moment I first wore the Gravity it became my go to shoe, and it remained my go to shoe for about 350 miles. I should qualify those miles. Nearly all of those 350 miles are trail miles, and the Newton Gravity shoes did not fail until I wore them for the Dipsea-Boy, an unofficial Trail-off trail adventure race. At some point during this race the glue holding the lugs part of the outsole to the midsole failed.

Unlike my experience with the Newton MV2, the upper remained in quality condition and would probably hold for hundreds of more miles.


Call for responses: I want to know what you think. Have you worn these shoes? Was your experience similar? Post questions and comments below.

  1. I wear both the Distance U (for speed work) the Gravity (for distance.) I am curious… how far has your longest run been? And have you ever considered wearing an orthotic?

    1. My longest run in this shoe was only about 16 miles (single track trail). I have experimented with various orthotics but ultimately default to no orthotic. I made my own orthotics for my morton’s toe, but rarely use them. I have also used semi-rigid arch support in the past, but retired them when I learned to strengthen the body to correct fallen arches.

      Are you considering orthotics? For what?

      1. Well, I am running in both the Newton Distance U (for speed work) and the Newton Gravity (for longer runs, 10 miles plus.) Honestly, I consider myself new to the whole natural running thing. I started running in the Newton at the end of April, but officially changed my stride to a natural running stride in September. I love the lightness of the Newton shoe compared to my old cushioned brooks. However, on longer runs between mile 8-10 I can really feel my forefoot rubbing against the ground. I almost thought it was blisters but there were no blisters there when I checked. Or could it be the lugs?
        This is not a painful feeling or a injury feeling. It is just a little bit of discomfort, but I am not sure exactly what is causing it. Maybe I need to strength train more, since I am now using different muscles. But a friend told me that there could be an imbalance in my foot. So I was considering trying an orthotic. I have two friends that wear the Newton shoe and wear orthotics with them. What do you think?

      2. Does it feel like you are running with a rock under your second or third toe? It is hard to tell exactly what the problem is from the description given, but it sounds like it may be a common running problem called Metatarsalgia. Below are some resources that may be helpful if that is indeed the affliction causing your pain. If it is so, there are lots of things to try and orthotics are one of them. First thing to try is to loosen the toe box. Newtons have not yet adopted the foot shaped toe box, loosening the shoe around the toes, or choosing a shoe with a wider toe box may alleviate the problem entirely (Everything from Altra, as Well as the Merrell Glove Series have a foot shaped toe box). This pain is also common in folks who have a big toe that is shorter than the second toe. In this case you may choose to get an orthotic under the ball of the big toe.

        This is just my best guess based on the description you have provided, make sure to do some research on your own, and definitely see a professional if the problem continues.

  2. I have been running for 37 years and lived thru two back surgeries, being hit bye a truck and having my left ankle broken, and last spring, I suffered a right lateral meniscus tear that required surgery and left me with a 40% meniscus loss. I found that newtons were the only shoes I could/can run in with no knee pain. I alternate sir isaacs and gravitys, and find I run well in both, but have to concentrate more on form with the gravitys. I have about 120 miles on each pair, and they show no wear at all. Most all of my running is on groomed dirt trails and asphalt bike paths here in southwestern new mexico. The few times i wore either on more technical trails, i didn’t like them. I think the best effect is on a smooth surface. I wish they made a newton trainer with the 5 lug pattern in a training shoe. the mv2 is just too light for my 6’3″ 180 lb frame. Anyway, nice review!
