Scarpa Neutron 2 Review Facts
Watch Video Review

Scarpa has described their Neutron line as their do-it-all running shoes, able to take on even the most challenging terrains but can still be used for casual jogs. The Neutron 2 definitely follows this pattern with its durable materials and sock-fit construction. The brand was smart enough to bring back all of the same features that runners loved in the first version. With that said, it definitely made some much-needed improvements. Its Vibram compound outsole now comes in a Genetic 2 Megagrip design for a stronger grasp on difficult surfaces. The compression-molded EVA midsole and H-EVA plate work together to provide cushioning, protection, and stability. Though its upper’s mesh material is still present, its synthetic leather has now been swapped out for micro-nubuck. Reviewers are also pleased to see that it has more colorways than before, although some have said they would have wanted more neutral options.

Outsole
Outsole

Outsole

Vibram rubber has been used to create durable outsole units for many different trail running shoes made by a number of different brands. Because Scarpa relied on them with their original Neutron model, it only makes sense that they would turn to them again when creating this second version. This model now features a Genetic 2 Megagrip outsole made this extremely sturdy compound, ensuring a long-lasting and powerful grip that can withstand technical trails. Its multi-directional gripping lugs, especially those around the edge of the outsole, prove to be especially helpful during uphill and downhill runs.
Midsole
Midsole

Midsole

Though standard EVA foam isn't nearly as durable as new technologies that are available today, it's much sturdier when it's been compressed. For this reason, compression-molded EVA is used to create the Neutron 2's midsole unit. Forming two separate units at the forefoot and heel, it provides the proper amount of cushioning and shock absorption for both segments. An H-EVA plate connects this two units, ensuring greater stability and protection against jagged surfaces. In addition, an ESS Ergonomic insert is put in place for some extra cushioning and underfoot support.
Upper
Upper

Upper

The Neutron 2's upper definitely seems more uniform when compared to its predecessor. Despite this, all of the same features as before are still present in this particular version. It's still made up of Micro-Nubuck and Mesh for a decent balance of protection and breathability. A TPU toe cap is still present to safeguard against potential trailing hazards. And its fabric lining ensures completely breathability along the forefoot and sides, where hotspots occur the most. The lace pocket within the tongue has also returned to prevent trips and falls. Its lacing system, on the other hand, has undergone an obvious change. Instead of traditional holes, it now consists of fabric loops that stick out from underneath the overlays to form a type of midfoot cage for a more secure fit.
Weight
Weight

Weight

Men's and women's sizes average out between 10 and 10.5 oz., meaning that the Neutron 2 is pretty standard when it comes to its weight. Many trail runners don't want their footwear to be too lightweight, as that extra mass ensures greater protection and durability. While this model does an excellent job at safeguarding the runner against many types of trail hazards, from jagged rocks to dirt and wet ground, it's still proven to be incredibly agile. Any shoe that's required to carry runners across challenging, mountainous terrains has to be easy to wear, and the Neutron 2 definitely fits this requirement.
Breathability
Breathability

Breathability

Because more than half of its upper is constructed of Micro-Nubuck, the Neutron 2 is obviously not going to be as breathable as other running shoes on the market. That said, its forefoot and sides are still covered with a great deal of mesh. Along with a soft fabric lining, it's able to quickly reduce hotspots in areas where they most occur. This also means a slightly cooler and dryer wear for the runner as they take on challenging terrains.
Comfort
Comfort

Comfort

Though most reviews focus more on the shoe's performance, several do mention that the Neutron 2 feels sufficiently comfortable. The compression-molded EVA midsole and H-EVA plate work together to keep the underfoot cushioned and protected against impact, and the Ergomatic insert keeps the runner's foot straightened to reduce the likelihood of long-term pain. The upper's sock-like construction gives a snug fit as the mesh segments and soft fabric lining ensure much-needed breathability. Unfortunately, this model doesn't always fit true to size. Some reviewers say that it feels too small, while others claim that it fits too large.
Style
Style

Style

Though it has the same silhouette, the Neutron 2 looks a bit different from the original model. The design of the second version consists of a main color all over the outside and an accent color for the detailing and inner sleeve. Its lined designs also extend from the midfoot to stretch towards the toes and around the heel. Just like its predecessor, reviewers are absolutely drawn to its vibrant color options. Depending on their sizing, they can easily choose between Black/Orange, Grecian Blue/Spring Green, Grey/Blue Radiance, or Black/Pink. For women, a Prism Violet/Red option is also available through certain retailers. The only real downside to these options is that they definitely aren't for everyone, as some buyers prefer their footwear to be more on the neutral side.
Durability
Durability

Durability

Aside from providing extraordinary traction, the outsole's Vibram compound also adds to Neutron 2's already impressive durability. The same can be said for the compression-molded EVA midsole, which holds up much better against normal wear than standard EVA foam. Though it's enhanced even further by the cushiony and protective H-EVA plate that's fixed on top of it. Because a regular mesh upper would not fair well in rugged terrains on its own, it's mostly covered in micro-nubuck to enhance its durability and prevent accidental tears. With the addition of a TPU toe cap and heel clip, runners have a highly durable trailing shoe that can withstand even the most rugged conditions.
Protection
Protection

Protection

Reviewers are pleased to learn that the Neutron 2 is just as protective as it is vibrant and colorful. Its outsole's sturdy Vibram compound safeguards the rest of the shoe against possible damage, and its multi-directional gripping lugs keep the runner completely secure on many challenging surfaces. The compression-molded EVA midsole cushions and absorbs shock in areas where it's needed most, reducing the likelihood of injuries and chronic pain. This is enhanced even further by the H-EVA plate, which also safeguards the underfoot against potential damage. The upper's snug fit and micro-nubuck material keep dirt and debris out of the foot chamber, while its mesh segments provide the necessary amount of breathability. Finally, a TPU toe cap is set in place to shield against bums and other potential trailing hazards.
Responsiveness
Responsiveness

Responsiveness

The act of creating a compression-molded EVA midsole ensures not only greater durability but also a higher amount of shock absorption, making it a much better fit when designing trail running shoes. Therefore, it's no real surprise that Scarpa relied on this material for creating both their original Neutron model and their second version. Covering both the forefoot and heel separately, it provides responsiveness only to the areas that need it the most. And with an H-EVA plate added on top of these segments, runners get an even more responsive wear as they take on a number of challenging terrains.
Support
Support

Support

The compression-molded EVA midsole and H-EVA plate already provide the runner with a supportive wear every time they use the Neutron 2 for trail running. Aside from giving a great deal of comfort, they also work together to absorb the shock of each impact. However, it's the shoe's mesh and micro-nubuck upper that really give it its highly supportive wear, thanks primarily to its sock-fit lightweight construction. This snug feeling is enhanced by an internal TPU midfoot cage, with built-in webbing making up the lacing system for a more secure and customizable fit. Even the collar is padded to support the ankles and keep the foot from accidentally slipping out.
Terrain
Terrain

Terrain

As a trail running shoe, the Neutron 2 can easily carry the runner through some of the more challenging terrains that they may come across. Most buyers have worn these of rocky, mountainous trails, especially when running sharp turns or up or downhill. Others have found that they work just as well in thick forests or on clay ground. Though it does work extremely well on wet surfaces, some have found that its performance suffers when used on mud.
Price
Price

Price

Most high-quality running shoes can cost anywhere between $120 and $130. At $135 across most online retailers, including the Scarpa website, the Neutron 2's price is definitely a bit higher than average. Though some runners aren't keen on spending this kind of money on their footwear, those who frequently go trailing say that it's worth it for a highly durable and effective running shoe. And its comfortable wear serves as an added bonus. As with most running shoes, lower prices can easily be found via Amazon or eBay.
Traction
Traction

Traction

Incredible traction is a must-have for every trail running shoe, and the Neutron 2 has proven to be very effective on many different surfaces. Made from a durable Vibram compound, its Genetic 2 Megagrip outsole is equipped with a number of multi-directional gripping lugs for a firm grasp that keeps up even the most sudden movements. The largest ones are placed around the perimeter of the sole, ensuring that the runner stays safe even when running up or downhill. Runners have found that it works just as well on mountainous trails as it does through forests and on loose or wet surfaces. However, some reviewers have pointed out that it doesn't perform as well on mud since its gripping lugs have been known to get clogged.
Flexibility
Flexibility

Flexibility

As with most trail running shoes, the Neutron 2 focuses much more on stability and protection than ensuring a flexible wear. Still, its dual-density midsole does enable an easier and more agile wear for those who need it. The compression-molded EVA segments that cushion the forefoot and heel are connected by an H-EVA plate to allow more natural movement. The same can be said for the mesh and micro-nubuck upper, although its snug wear may be a bit too restrictive for some people.
Stability
Stability

Stability

The Neutron 2's sock-fit lightweight construction already provides the runner with a great deal of stability, thanks to its snug and secure fit without creating pressure points. But both of these qualities are aided even further by an exoskeletal TPU midfoot cage, integrated within the webbing-based lacing system. It also comes complete with a TPU heel clip and padded collar to really keep the foot from wobbling. Of course, the runner wouldn't feel nearly as stable if the shoe did not include a responsive compression-molded EVA midsole and a Vibram Genetic 2 Megagrip outsole. Both work together to ensure a cushioned and completely safe run across challenging surfaces.
Drop
Drop

Drop

It’s actually quite common for trail running shoes to have a much lower heel-to-toe drop than most casual footwear. The Neutron 2 follows this by having a drop height of only 6mm, permitting the runner a greater sense of balance and letting them feel closer to the ground while still providing decent heel cushioning. However, it definitely won’t be fit for those who prefer zero drop platforms.

Bottom Line

The Scarpa Neutron 2 has definitely proven that it can live up to its predecessor in terms of performance. Runners are pleased to know that it provides the same great traction as before, with some saying that it functions even better than before. They can also get some added protection and a sock-fit construction, along with the same amount of breathability that they're used to. As an added bonus, they've also been treated to new colorways and more eye-catching details. There is still some room for improvement when it comes to its sizing and traction, and some reviewers do wish that they had some neutral colorways. But, overall, this model proves to be a durable, protective, and stylish asset to everything from technical trails to casual runs.
