Newton Gravity 7 Review Facts
Watch Video Review

The Newton Gravity 7 is a lightweight racing shoe meant for sprinters to have in their regular rotation for days when they really want an ultra-responsive, ultra-flexible shoe that will propel them forward and encourage smooth heel-to-toe transition. This low-drop springy shoe features high-quality materials, as well as a breathable, engineered mesh upper that can be loosened up or tightened up a bit, according to the individual runner’s needs. This definitely isn’t the shoe for the average, around-the-block runner, which begs the question of whether it’s worth the price. Bottom line: if you specifically need a good performance-oriented sprinting shoe, the Gravity 7 is your cup of tea.

Outsole
Outsole

Outsole

The Newton Gravity 7 features a SHARC outsole, which looks peculiar, to say the least, and has a phalangeal-like shape, providing increased traction and flexibility, as well as durability. The forefoot area dons a high-density, durable rubber that will provide you with a long-lasting performance and prevent wear and tear of the outsole. The material on the outsole is made to perform the same in wet and dry conditions, making this shoe a versatile choice for outdoor runners. The forefoot has deep groove cuts the entire width of the outsole, increasing the flexibility of the shoe and enabling a quick toe-off. When absorbing the impact, the lugs recede into the filled chambers, which makes the runner feel grounded and provides great energy return.
Midsole
Midsole

Midsole

The technology of the Gravity 7’s midsole hasn’t changed from the previous version, so we can expect the same things from it, performance-wise. The high-rebound EVA midsole is cushioned and durable, and while it’s not immune to flattening and small tears, the durable rubber outsole will protect the midsole from any serious deterioration. The Newtonium Cushioning System provides great cushioning, as well as good rebound, keeping the foam close to the foot. This cushioning system increases the responsiveness of the shoe greatly and provides a more energetic ride. The heel and forefoot area feature the Action/Reaction technology, which offers more energy return and encourages a smooth heel-to-toe transition.
Upper
Upper

Upper

The shoebox of the Newton Gravity 7 features the anti-bacterial ETC Sockliner, which is integrated into the shoe with the primary goal of increasing the overall comfort. The brand claims the sockliner will promote a healthy foot environment, which turned out to be a true statement because a lot of runners have commented on the fact that the shoe hasn’t become the least bit smelly during the first 100 miles, which is an achievement. The upper itself is made out of seamless engineered mesh that allows lots of air circulation in the shoebox. In the front of the shoe, stitched to the upper is the Strobel Last, which adds a bit of stability and structure to the otherwise sock-like upper. The Heel Lace Lock provides additional security and keeps the heel tight.
Weight
Weight

Weight

At 8.7oz for a half-pair of the men’s size 9, this is, without a doubt, a lightweight shoe that would hardly be felt on the foot. The vast majority of runners have commented how light, fast and seamless the Gravity 7 feels and not a single runner has complained to the weight not being appropriate for this type of a running shoe.
Breathability
Breathability

Breathability

The lightweight engineered mesh material used in the upper construction provides the Newton Gravity 7 with lots of breathability, especially because the tongue of the shoe is made out of the same mesh material as the upper. The lack of stitches and seams means no overlays, and no overlays means less fabric to suffocate the foot. This way, Newton has built a shoe that won’t make your feet overheated, uncomfortable, or sweaty.
Comfort
Comfort

Comfort

The Newton Gravity 7 provides a really tight and secure fit at the heel and the midfoot, while the forefoot is wider and roomier than the rearfoot of the shoe, although nothing too wide by any means. The Gravity 7 is very comfortable right out of the box, and you can individualize the fit by adjusting the 4-way stretch mesh metatarsal panel, which offers added support and structure to the upper and, consequently, the foot. This shoe runs true to size and offers a great fit, especially to people with normal feet width ( it comes in standards medium D and B widths). Most runners have described the Gravity 7 as really comfy, with a few stating that they wouldn’t stay in this shoe the whole day, because the specific build of the outsole prevents it from staying equally as comfortable as time goes by.
Style
Style

Style

Let’s put it this way: the Newton Gravity 7 isn’t the type of shoe you want to buy if you want to stay low-key. On the contrary, the color palette used with the Gravity 7 is bold, vibrant, and in-your-face kind of beautiful. Either you love it, or you hate it, and a lot of runners seem to like it very much. Additionally, the shoe has a super-useful feature: the 360-degree reflectivity, which makes it even more visible on evening runs.
Durability
Durability

Durability

The high-rebound EVA foam used for the midsole construction offers good responsiveness paired with durability. A number of runners have commented on the fact that even after 100 miles, the cushioning of the midsole has stayed the same, which is an impressive result. However, people have noticed some wear on the lateral sides of the foamy midsole, but luckily, it’s mostly protected from abrasion by the rubber outsole. The outsole itself is pretty durable as well, with the combination of sturdy lugs and high-density rubber that makes the shoe average to long-lasting. The only weak spot in the shoe is the engineered mesh upper, which is prone to experiencing wear and tear sooner than the sole.
Protection
Protection

Protection

A lot of runners have been more than pleased with the cushioning of the Newton Gravity 7 and the impact protection it offered on short runs. However, keep in mind that this isn’t a marathon shoe, or a shoe meant for long runs and whole-day activities, in which case the cushioning and the outsole build won’t protect you from impact stress, long-term. The stitched toe bumper on the front of the upper will provide basic protection from rocks and uneven surfaces that might hurt your toes, but it’s mostly there to provide some structure to the upper.
Responsiveness
Responsiveness

Responsiveness

The brand has put their Newtonium foam to good use with the Gravity 7 and has put it almost directly under the foot, for added responsiveness. The foam itself is light and springy and does its job perfectly. The lugs on the outsole recede into the air-filled chambers inside the sole, creating amazing momentum and energy-return by manipulating air pressure and propelling the foot forward. All in all, the Gravity 7 provides amazing energy return, which, combined with the fact that this is a shoe made for short runs, is ideal.
Support
Support

Support

The Newton Gravity 7 s a neutral running shoe, meaning that it will be best suited for people that don’t require additional arch support, which is around half of the total number of runners out there. If you have Normal, medium-high or high arches, this is the right shoe for you. As far as heel support goes, the Gravity 7 features the molded heel counter which provides a firm fit and support, as well as a significant amount of comfort.
Terrain
Terrain

Terrain

This shoe is best for running on flat surfaces: roads, track, light gravel, or a treadmill. Also, due to its flexibility and responsiveness, it will perform great during HIIT workouts and tempo runs. Its lightweight and construction make this a great racing shoe. However, keep in mind that this isn’t an everyday shoe intended for long runs, but rather a performance-oriented running shoe well worth keeping in your rotation.
Price
Price

Price

The price point of the Newton Gravity 7 is higher than expected, and, in our opinion, higher than necessary. At such a steep price for a racing shoe suitable only for shorter runs, it’s unclear why the brand picked the price they did and who will be able to afford this shoe. However, if you do need a high-quality, ultra-responsive racing shoe with a specific outsole construction in your rotation, the Gravity 7 is an excellent choice, without a doubt. However, if you just need a regular running shoe that’s high quality, then the Gravity 7, at its price, will have to compete with the likes of Brooks Levitate and Glycerine and Adidas Ultra Boost, for example, which is a competition it’s unlikely to win.
Traction
Traction

Traction

While the brand claims that the rubber on the outsole of this running shoe performs equally as good on wet and dry surfaces, some of the runners who have tested the shoe would have to disagree with that statement. The traction on dry terrain is fantastic, while the traction on wet surfaces is often unreliable, so keep that in mind if you live in a rainy area and you like to run outside.
Flexibility
Flexibility

Flexibility

The Newton Gravity 7 is flexible inside and out. Starting from the receding lugs and the outsole grooves that enable great forefoot and toe flex, to the high-rebound, springy and flexible EVA midsole, to the engineered mesh upper than adheres to the foot and moves with it, the flexibility of the Gravity 7 is nothing short of impressive.
Stability
Stability

Stability

The brand has decided to accentuate the heel stability with the Gravity 7 and most runners agree that this was a good move. The rearfoot area of the shoe uses a firm heel cup that locks the heel in and stabilizes it by preventing wobbling, sliding around, or slipping out of the shoe box. Additionally, the lacing technology on the shoes enables you to decide how tight you want the whole upper to be, which can add to the overall stability of the foot.
Drop
Drop

Drop

This is a low-drop shoe that is entirely focused on flexibility, responsiveness, and natural foot movement, which explains the slight 3mm difference between the heel stack height of 26mm and the forefoot stack height of 23mm. This means that it’ll take some time for you to get used to this drop, especially if you’re coming from a higher drop shoe of 10, 12 or even 16mm (in which case we strongly recommend going for a transition shoe first!). The heel of the Gravity 7 is completely out of the way, and the barefoot feeling the shoe promotes makes you watch your running form carefully. It’s even possible that you’ll go through a period of your calves, ankles and even Achilles hurting, but this is, for most runners, a temporary sensation that’ll go away once you get used to the almost-flat drop.

Bottom Line
Bottom Line

Bottom Line

Overall, the Newton Gravity 7 is a great addition to any runner’s shoe rotation. The shoe is so responsive and flexible that it’s bound to up your performance on 200m and 400m runs, but don’t expect it to offer all-day cushioning and comfort – that’s not what this shoe is about. The low 3mm drop will take some time getting used to, so be prepared to feel the pain before you feel the pleasure. The fit of the shoe is impressive, and the cushioning is great, while the weird-looking outsole does allow for good ground feel and a swift heel-to-toe transition. If we were to advise you on whether you should buy the Gravity 7 or not, our answer would be yes – on a sale.
