Newton Gravity 12 vs Motion 13: Women’s Shoe Review

We love talking running shoes, and choosing between the NEWTON Running Women’s Gravity 12 and the NEWTON Running Women’s Motion 13 Running Shoe – Versatile Stability Trainer with Enhanced Performance is a great place to start when you’re looking for a performance-focused daily trainer. Both shoes carry Newton’s signature design cues—forefoot lugs that encourage a more efficient toe-off and a lively, responsive ride—but they aim at slightly different needs: the Gravity 12 leans toward a snappy, lightweight feel for quicker efforts, while the Motion 13 brings more structured support and versatility for runners who want stability without sacrificing responsiveness.

A bit of context helps: Newton made a name by designing shoes that promote a more natural, efficient stride through targeted forefoot propulsion, and over the years the line has branched into models that prioritize responsiveness, cushioning, or stability. Owning one of these types of shoes can improve running economy and cadence for many runners, offer a more energetic toe-off, and reduce the need for excessive cushioning while still providing protection on daily runs. The Gravity line typically appeals to runners chasing a fast, lively trainer, whereas the Motion line is built for those who want that Newton feel but need extra guidance and support. In the article we’ll take a closer look at each model’s fit, cushioning, stability features, and ideal use cases so you can decide which NEWTON shoe best matches our running goals.

Newton Women’s Gravity 12 running shoes

We see the NEWTON Gravity 12 as a true speed trainer built to shine on shorter, more intense sessions. Its strengths make it ideal for track workouts, tempo runs, and quick road miles. If you’re planning intervals, fartleks, or cruise repeats where responsiveness and a snappy feel matter, this shoe is exactly the sort of tool we reach for.

We recommend the Gravity 12 to runners who enjoy a lively, performance-oriented ride. That includes women who:

• Want a lightweight trainer that still offers noticeable cushioning.
• Prefer a shoe that accelerates transitions and amplifies turnover.
• Need something versatile enough to handle both track sessions and short to mid-distance road efforts. If you’re chasing marathon-level miles or long, cushioned recovery runs exclusively, there are more cushioned options. But for most of our faster training days, the Gravity 12 hits the sweet spot.

We love how the NEWTON Gravity 12 blends liveliness with cushioning in a package that feels modern and purposeful. From the first run, it delivers a confident and energetic toe-off thanks to the combination of NRG foams, Hytrel, and an XPS performance plate. The result is a shoe that makes easy runs feel peppier and threshold efforts feel more efficient.

The shoe fits true to size for most of us, offering a secure midfoot and a roomy toe box that keeps toes comfortable on faster efforts. The upper strikes a nice balance between breathable and supportive — it hugs without squeezing and lets us push without hot spots forming. We appreciate the slightly padded tongue and the structured heel cup that locks our foot in place during aggressive accelerations.

• The updated foam stack creates a perceptible boost in responsiveness — the shoe returns energy the moment we push off.
• The XPS performance plate keeps the gait smooth and directed forward, which is especially helpful during tempo runs and intervals.
• Despite being a speed trainer, the Gravity 12 still offers enough cushioning to keep shorter recovery runs comfortable, so we don’t have to swap shoes between sessions.

The NEWTON Gravity 12 is designed as a lighter, quicker training option that sits squarely in the speed trainer category. Its purpose is to help runners move more dynamically through the gait cycle while maintaining a comfortable level of shock absorption. Whether we’re on the track, the neighborhood roads, or the treadmill, the Gravity 12 aims to make workouts feel sharper and faster.

We’ll highlight the most important features that define this iteration:

• NRG foam: This updated foam provides a springy, responsive feel underfoot, enhancing the shoe’s liveliness without sacrificing support.
• Hytrel: A new foam compound that adds resilience and a slightly softer land, improving comfort during repeated intervals.
• XPS performance plate: Engineered to amplify forward propulsion, the plate helps deliver quick toe-offs and efficient transitions through toe strike.
• Lightweight, breathable upper: A modern woven or mesh material that balances ventilation with secure lockdown.
• Durable rubber outsole: Strategically placed rubber helps with traction and longevity, particularly on road surfaces.

When we lace up the Gravity 12, the NRG and Hytrel foams immediately change how our foot feels on impact — it’s cushioned yet responsive. As we accelerate, the XPS performance plate guides the motion forward, creating a propulsive sensation that makes cadence increases feel more natural. The upper secures the foot so the energy generated is efficiently transferred from foot strike to toe-off. Altogether, the shoe functions as a cohesive unit designed to make faster running less fatiguing and more enjoyable.

The Gravity 12 feels premium for its class. The materials are well-chosen: the upper isn’t overly flashy but it’s durable and breathable; the midsole foams are refined and carefully tuned; and the outsole rubber is applied where it matters most to preserve weight while improving longevity. Stitching and assembly are clean, and we’ve seen no loosening seams or premature wear during our testing window.

Ride quality is the standout attribute. The Gravity 12 manages to be both quicker and more cushioned, which is a tricky balance. The foams absorb repeated impacts without feeling dead or mushy, and the plate provides a snappy, energetic finish to each stride. For runs up to an hour or for high-intensity sessions, this shoe provides a confidence-inspiring mix of comfort and performance.

Over several test runs, the outsole shows only expected wear patterns for a speed trainer. The tread compounds hold up well on asphalt and track surfaces. The midsole retains responsiveness after repeated intervals, which speaks well for the NRG and Hytrel blend. If you put high weekly mileage or heavy long-run days on the shoe, it will eventually show signs of compression — but that’s normal for a trainer optimized for responsiveness over maximal longevity.

Sizing is generally consistent with NEWTON’s women’s line. The Gravity 12 offers a reassuring midfoot lockdown and a forgiving forefoot. We recommend trying usual running shoe size or consulting a store fitter if between sizes. For orthotics or high-volume feet, a size up may be worth considering.

• Bold responsiveness: The combination of NRG foam, Hytrel, and the XPS performance plate makes the shoe feel lively and energetic.

• Versatile speed trainer: Great for track workouts, intervals, tempo runs, and quick road miles.

• Balanced cushioning: More plush than a pure racer, yet still delivers a fast feel — ideal for runners who want speed without a brutally firm ride.

• Lightweight and breathable upper: Keeps feet cool and secure during higher intensity efforts.

• Clean construction and thoughtful material placement: Good value for a performance-focused trainer.

• Limited long-run comfort: While cushioned for a speed shoe, it may not be the best choice for very long runs where maximal soft cushioning is preferred.

• Durability trade-offs: As with many responsive trainers, the midsole foam will compress faster under high mileage than a bulkier, maximal-cushion trainer.

• Price point: Performance features mean a premium price compared to basic daily trainers.

• Not ideal for those who want a completely neutral, plush feel — the plate results in a directed, slightly firmer sensation.

If your weekly routine is dominated by ultra-long runs, long-distance races, or you want a soft, plush daily trainer for recovery days, we’d suggest looking at more cushioned models. Similarly, if you prioritize minimal structure and maximal flexibility, the Gravity 12’s plate and forward-biased geometry may feel too guided.

We’ve found the NEWTON Gravity 12 to be an excellent addition to our rotation when we need a shoe that can handle fast efforts and shorter tempo sessions with style and substance. The product description captures its essence well: “Light Speed. Our legendary speed trainer gets upgraded with new NRG and Hytrel foams and XPS performance plate to amplify cushioning and responsiveness. Quicker, more cushioned and dynamic it’s perfect for anything from track workouts to quick road miles.”

When pairing it in our lineup, we often alternate the Gravity 12 with a softer daily trainer — using the Gravity 12 for intervals, strides, and tempo runs, and a maximally cushioned shoe for long recovery jogs. This approach lets us exploit the Gravity 12’s strengths without overexposing the midsole to daily heavy mileage.

Our testing suggests the Gravity 12 will appeal to runners seeking a modern, lively trainer that boosts turnover and makes faster runs feel more efficient and enjoyable. It’s a friendly, capable shoe that does what it promises: deliver a quicker, more responsive ride while not abandoning the comfort we want on training days. If your training includes a fair share of higher-intensity sessions, we think the Gravity 12 deserves a spot in your shoe rotation.

Newton Women’s Motion 13 Running Shoe — Stable, Versatile Trainer

We tested the NEWTON Running Women’s Motion 13 with our regular rotation of training and tempo runs to get a sense of how it performs as a versatile stability trainer. Over multiple weeks and varied surfaces, we formed a clear sense of where this shoe shines and where it might not be the best fit for every runner. Below, we break down the key points from our experience.

primary use

Ideal activities and runner profile

We see the Newton Motion 13 as a shoe built for everyday training with a bias toward runners who want a little extra stability without sacrificing responsiveness. This makes it a strong choice for:

• Daily miles and easy runs
• Steady-state and tempo runs
• Short to medium-distance long runs
• Light cross-training or gym sessions that involve running drills

While it can handle faster-paced workouts, we think the Motion 13’s sweet spot is the runner who wants a stable, responsive cushioning platform for a variety of workouts rather than a race-day flat. It’s particularly attractive for runners with neutral to mild overpronation who prefer a guiding, not intrusive, stability feel.

why we like this product

What stood out for us

There are several reasons we found ourselves reaching for the Newton Motion 13 again and again during our test period:

• The combination of stability and propulsive feel. Newton’s emphasis on forefoot propulsion (those signature forefoot lugs) gives a lively toe-off that keeps runs feeling efficient.
• A comfortable, breathable upper that supports without squeezing — we appreciated the balance of structure and stretch.
• Versatility across paces. We could comfortably use these for recovery runs, steady miles, and tempo efforts without feeling under- or over-cushioned.
• A reassuring ride for those who want subtle guidance toward a more midfoot-to-forefoot transition rather than heavy corrective support.

The Motion 13 gives us confidence on varied runs while still feeling light on the legs. That blend of everyday usability and a touch of performance-oriented design is why we like it.

an overview of the products purpose and key features

Design intent and main technologies

The Motion 13 is positioned as a stability trainer that does not compromise on energy return or responsiveness. Its design purpose is to provide a smooth, efficient run for everyday training while helping runners who need mild support stay aligned.

Key features that define the shoe’s purpose:

• Propulsive Forefoot Lugs: Newton’s recognizable lugs under the forefoot encourage a forward-driving toe-off. We felt this most on tempo efforts and rolling terrain.
• Balanced Cushioning: The midsole offers enough cushion for comfort on longer runs but retains enough firmness to preserve responsiveness. The result is a ride that feels lively instead of mushy.
• Subtle Stability Elements: Instead of heavy medial posting, the Motion 13 uses geometry and midsole shaping to provide a stable platform. That provides support without the intrusive feeling we sometimes get from more corrective shoes.
• Breathable Engineered Upper: The mesh upper is breathable and adapts to foot shape, reducing hotspots and allowing for a comfortable fit throughout runs.
• Durable Outsole: We noticed good grip and wear resistance in our testing, which is important for a daily trainer.

Fit, feel, and sizing

The Motion 13 tends to fit true to size for us, with a slightly roomier forefoot that accommodates toe splay on longer efforts. The heel lock is secure without being tight, and the midfoot provides a reassuring cradle. If you prefer a snug, racing-style fit you might consider going down half a size, but for most of our team a standard size felt best.

Ride characteristics

From the first step, the shoe feels intentionally designed to promote an efficient forward roll. The forefoot lugs make their presence known during toe-off — we experienced a subtle spring that encouraged a quicker cadence without forcing form changes. The midsole cushioning sits in the moderate range: softer than a stability racing flat, firmer than a cushy road max trainer. That middle ground is what makes the Motion 13 a versatile daily option.

overall quality

Build, materials, and durability impressions

We assessed the Motion 13 over a mix of pavement, light trail connectors, and gym surfaces. The build quality feels solid:

• The upper materials show thoughtful reinforcement at stress points (heel and toe) and use a close-knit mesh where ventilation and light support matter most. Despite repeated miles, we did not see early fraying or seam issues.
• The midsole retains its responsiveness after extended runs; we didn’t notice rapid compression or a “dead” feeling even after multiple weeks of use. That speaks well for midsole compound resilience.
• Outsole durability is good — the rubber compound used in high-wear areas resists early scuffing and flattening. Tread wear after our test period was moderate, suggesting this shoe should hold up for a typical training rotation of several hundred miles for many runners.
• Stitching and glue lines were tidy on our pair, indicating solid manufacturing consistency.

From a quality standpoint, the Motion 13 feels like a premium trainer that competes well in its category. It’s not overbuilt, but the materials and assembly deliver confidence that the shoe will perform as promised across a range of training situations.

pros and cons

Quick snapshot

Pros:

• Versatile stability trainer — great for daily miles and varied workouts.
• Responsive forefoot propulsion thanks to the signature forefoot lugs, which help with a lively toe-off and efficient cadence.
• Comfortable, breathable upper that fits well and reduces hotspots.
• Balanced cushioning that blends comfort with responsiveness — not too soft, not too firm.
• Durable outsole with consistent traction on pavement and light terrain.
• Subtle, non-invasive stability aimed at neutral to mild overpronators.

Cons:

• The propulsive lugs may feel unusual for runners accustomed to very cushy, soft trainers; there is a short adaptation period.
• Not the best choice for runners needing heavy corrective support — the stability is guidance-based rather than corrective posting.
• Some runners may prefer a snappier race-day shoe for tempo races or marathons; while versatile, the Motion 13 is more of a daily trainer than a flat-out racer.
• Heel-to-toe transition may feel different to those used to maximalist shoes or very soft midsoles.

We found the pros significantly outweighed the cons for our use cases. The Motion 13’s personality is distinct: it rewards forward motion and efficient turnover. Runners who like to feel engaged in their stride will likely appreciate that, while those who want plush, cloud-like cushioning may want to try the shoe before committing.

Throughout our testing, the shoe’s strengths were most evident on runs where we wanted to maintain a steady rhythm—longer tempo runs, progression workouts, and easy days where maintaining cadence matters. The shoe’s stability characteristics feel intelligent and unobtrusive, and the overall design encourages a natural, forward-driving gait.

If we had to summarize what type of runner would most benefit from the Motion 13, we’d point to someone who trains frequently, favors an efficient, slightly forward-leaning stride, and wants mild guidance for pronation without the feel of a corrective device. For those runners, the Motion 13 strikes a compelling balance between comfort, stability, and performance.

We encourage runners curious about a stability trainer that still feels lively to give the NEWTON Motion 13 a try — especially if they value a shoe that transitions smoothly from easy miles to quicker efforts while offering dependable daily durability and a unique propulsive feel.

Conclusion

We enjoyed testing both the NEWTON Running Women’s Gravity 12 and the NEWTON Running Women’s Motion 13, and each shoe brings a clear personality. The Gravity 12 is lively and responsive — built for quicker paces, tempo runs and runners who like a bouncy, forefoot-forward feel. The Motion 13 is the more structured option — a versatile stability trainer that delivers support for runners who need a little extra control without sacrificing everyday performance.

Drawbacks

• Shared drawbacks

  • Both shoes lean toward a firmer, more responsive ride rather than plush cushioning, so they may feel harsh on very long recovery days or for runners who prefer maximal softness.
  • Runners who are new to Newton’s lug/forefoot-focused platform may need a short adaptation period to get the most comfortable gait with these models.
  • Fit can be personal — some runners find Newtons a bit snug in the toe box or narrow across the forefoot, so trying them on or checking return policies is wise.

• Gravity 12 specific

  • Less ideal for very long, slow endurance runs where extra cushioning and underfoot softness are desired.
  • Best for runners comfortable with a somewhat aggressive forefoot propulsion — casual runners who heel-strike heavily may not appreciate the platform right away.

• Motion 13 specific

  • Adds stability features, which can make the ride feel a touch heavier or less lively than the Gravity for faster workouts.
  • If you don’t need stability, the Motion 13 may feel bulkier than necessary for speed sessions.

Recommendation — who should buy which

• Choose the NEWTON Gravity 12 if:

  • You want a responsive, energetic trainer for tempo runs, intervals, and faster daily miles.
  • You’re comfortable with a forefoot-biased platform and prefer a snappy, propulsive feel.
  • You’re an experienced runner or someone transitioning deliberately into Newton’s style.

• Choose the NEWTON Motion 13 if:

  • You need mild-to-moderate stability (overpronation control) but still want a shoe that performs across daily training.
  • You prioritize a balanced, supportive ride for mixed workouts and steady miles rather than pure speed.
  • You want a versatile everyday trainer that helps maintain form without being an overly cushioned maximal shoe.

Overall, if we had to pick for different audiences: pick the Gravity 12 for runners chasing speed and responsiveness; pick the Motion 13 for runners seeking reliable stability and everyday versatility. In either case, we recommend trying them on (or ordering from a retailer with a good return policy) and allowing a few short runs to adapt to Newton’s unique platform before committing them to long or race-day efforts.
