Our verdict

New Balance’s first trail supershoe attempt shows promise but fades before crossing the finish line. We found that it delivers an ultra-soft, lightweight ride with a top-class Vibram outsole. However, the previous-gen, non-PEBA FuelCell foam left some energy return on the table. In our lab tests, the midsole felt plush but not as responsive as other high-performance trail shoes. Fortunately, the price reflects this, making it more accessible than most competitors. For us, it delivers speed and fun on trails, but still lacks true supershoe status.

Who should buy

We believe the New Balance New Balance Trail Running 703 Trail Running Παπούτσια is a strong choice for:

  • Runners who love the cloud-soft feel of FuelCell cushioning and want to experience it on trails.
  • Ultra-marathoners who heel strike and need a protective, plush-yet-grippy option for racing and training.
  • New Balance Girls 680v6 Grey Blue Pink 13.5.

Who should NOT buy

We think the SuperComp Trail isn’t the best choice for midfoot or forefoot strikers due to its steep drop. The cushioning is heavily concentrated in the heel, leaving the forefoot with significantly less protection. If you prefer a racing shoe better suited for a forward landing, we recommend the Adidas Terrex Agravic Speed Ultra or the Saucony Endorphin Edge.

Additionally, the narrow toebox could be a deal-breaker for many runners. We’ve found that it restricts toe splay, making it a poor match for those with wider feet or anyone who values extra space for comfort. If that’s a concern, we suggest looking at the Nike Ultrafly or the Altra Mont Blanc Carbon, both performance shoes that offer a roomier fit paired with a Vibram outsole.

Cushioning

Heel stack

Runners seeking substantial heel cushioning will appreciate the New Balance New Balance Trail Running 703 Trail Running Παπούτσια, which boasts a 34.7 mm stack height. This makes it a strong choice for heel strikers needing plush comfort, even for ultra distances.

Forefoot stack

The forefoot felt much thinner than expected—New Balance listed it at 26.5 mm, but we measured only 21.7 mm. This lean platform results in noticeably lower cushioning, making it a less-than-ideal choice for non-heel-strikers seeking a protective ride.

Drop

That leaves us with a real heel-to-toe drop of 13.0 mm—an eye-opening difference that makes this shoe a strong choice for extreme heel strikers. However, we think that most midfoot and forefoot runners won't enjoy this shoe at all, it's too steep.

And why such a big difference? The midsole shape is undeniably unique, and New Balance likely measured the drop wherever it suited them. From our side, we tested it at World Athletics' official points—just like every other shoe we analyze here in our lab—to ensure precise-and-consistent results.

Midsole softness

Note: a low durometer measurement equals a soft material, sticas a high measurement means it's firm.

zapatillas de running New Balance mujer talla 43 rojas Жіноча футболка new balance, FuelCell is known for its ultra-soft feel in most models, but we weren’t sure if New Balance would maintain that plush-and-bouncy sensation in a trail shoe. After testing, we discovered that they absolutely did.

We recorded an incredibly-low reading of 11.5 HA—about half the average! That’s shockingly-soft for a trail shoe, and we’re convinced many runners will feel that, out in the mountains, a parece-and-stabler platform would provide better balance and security. On the other hand, for those who love ultra-soft running shoes and plan to stay on easy trails or gravel roads, this shoe could be a game-changer.

However, don’t expect top-tier energy return—this is the older TPU-based FuelCell from the New Balance Uomo 997H in Grigio Nero, not the PEBA-powered version found in the New Balance Donna 373v2 in Rosa Marrone Beige. That upgrade will have to wait for version 2.

The heel features a slight curvature to ease transitions for heel strikers, while the forefoot has a moderate toe spring. We found that it starts early and rises just 4 cm, avoiding the exaggerated lift seen in some road shoes. Женские кроссовки new balance 574 black pink.

Plate

New Balance’s effort to create a trail supershoe had to include a carbon plate, and it delivers. The plate follows the usual shape until the forefoot, where it disappears in our video and splits in two—a design choice seen in other high-performance trail shoes.

This forked design enhances torsional flexibility while preserving the plate’s propulsive benefits and added stability.

New Balance Trail Running 703 Trail Running Παπούτσια | New Balance Heren Fresh Foam Roav v2 Maat 40

The SuperComp Trail measures a slim 93.5 mm, favoring a race-ready, locked-in fit rather than a roomy feel. That’s expected for high-performance shoes, so it didn’t come as a surprise here in the lab.

We found that this shoe best suits runners with narrow to average foot widths. Despite being a New Balance (known for offering wide sizes even in niche models) this one is only available in a standard width.

Stability

Lateral stability test

If you need a stable yet fast trail shoe, this isn’t the right pick.

The ride is undeniably exhilarating and fun, but the SC Trail’s narrow-and-unstable build, paired with its ultra-soft foam, makes it risky on moderate and technical terrain. As expected, it’s best suited for neutral runners.

Torsional rigidity

Even with its forked plate and outsole grooves designed to enhance torsional flexibility, the SuperComp Trail still earned a max 5/5 in our test.

We previously mentioned the shoe’s narrow build, but now we have the numbers to back it up. Measuring 109.3 mm at its widest forefoot point, it’s designed for those who dislike the oversized designs of recent years.

Weight

If there’s one thing that truly impressed us about the SuperComp Trail, it’s how incredibly light it feels underfoot. At just 8.75 oz or 248g, it delivers a barely-there sensation that's amazing at faster paces.

Beyond just weight, we found that its streamlined design amplifies that nimble feel. In our view, this is the standout feature of this shoe.

Breathability

When unboxing the New Balance Trail Running 703 Trail Running Παπούτσια, we immediately noticed its design aimed at balancing airflow and durability.

After connecting our smoke machine to the SC Trail, we concluded that it was a 4/5 score for us. This is quite an improvement over many competitors, although, to be fair, at the high price of this shoe, we were expecting top-tier materials throughout.

We moved the upper over a LED light and discovered that, despite sharing the same mesh riddled with ventilation holes, those are only effective in the toebox, as the rest of the shoe has a thicker layer beneath for improved structure and stability.

Another subtle and premium touch comes from the insole. Instead of using a regular one, New Balance inserted a thin, perforated footbed that improves airflow.

New Balance New Balance Trail Running 703 Trail Running Παπούτσια microscope

Sometimes, trail shoes come without ventilation holes to improve durability, but it was not the case of the SuperComp Trail. We will find pretty soon if that's a good idea or not in terms of wear resistance.

Finally, the upper doesn't come with tons of padding, but we can't forget that this is a shoe made for racing, so it makes sense. What it does feature is the usual Toe Protect design from New Balance to prevent early wear and protect the toes (hence the name) from hard impacts.

Outsole hardness

The outsole is one of the most intriguing aspects of the SuperComp Trail, as it features Vibram Megagrip Litebase—arguably one of the best high-performance rubbers for trail running. If not the best.

New Balance New Balance Trail Running 703 Trail Running Παπούτσια outsole design
Maybe the rock-trapping central cutout was an unnecessary design choice.

It delivers excellent traction, and despite featuring low-profile lugs that we’ll discuss shortly, we found that it grips remarkably well even on moderate terrain. However, its true strength lies in fast-and-smooth trails. That said, there’s more exposed midsole than we typically see, which could raise drops for some runners.

For hardness, we measured 86.0 HC—right in the average range. Based on our findings, this should provide solid longevity while maintaining the outstanding grip we experienced on the trails.

Outsole durability

Since this is the Litebase version of Megagrip, we knew durability wouldn’t be outstanding—but it’s still acceptable. Our testing showed exactly 1.0 mm of wear from the Dremel, which we believe is reasonable for this type of outsole focused on weight reductions and top-tier grip.

Misc

Lug depth

This shoe is specifically built for smooth, long-distance ultras on western-states-style terrain, where impact protection and shallow lugs create an ideal combination. However, the lugs incorporate Vibram’s Traction Lug technology, which enhances grip, making them perform like slightly-thicker ones especially taking corners.

Still, with just 2.9 mm of depth and the SC Trail’s unstable platform, we think it’s best suited for easy trails, where it truly excels.

Tongue padding

The New Balance New Balance Trail Running 703 Trail Running Παπούτσια is impressively-light on its own—especially for a trail shoe. Therefore, a padded tongue was never an option, as it would have added too much weight, impacting the shoe’s streamlined design.

The tongue includes two loops to keep it centered, while an extra eyelet enhances ankle security.

That’s why we weren’t surprised to measure just 2.5 mm of thickness, which seems reasonable for a performance-driven model. However, based on our findings, runners tackling ultra races should take extra care when tightening the laces to avoid pressure points.
