The lightest running shoes

The lightest running shoes

This article has been updated with current models for November 2021. The Hoka Rincon 2 and Saucony Endorphin Speed have been replaced with their updated versions. The New Balance Fuelcell Rebel V2 and Nike Vaporfly Next % 2 are new additions. Except for the narrower ‘B’ width, the women’s models are identical to men’s.

The easiest way to write this guide would be to compile a list of lightweight running shoes with their weights sorted in ascending order.

But that would be a completely pointless exercise, because that list would be full of impractical racing flats. A more effective approach is to group the shoes by use-cases – in the same way how most of our other guides are structured.

If this piece was written a decade ago, most lightweight shoes would have featured injection-molded EVA midsoles with a token placement of outsole rubber.

Back then, running shoes had to conform to a strict weight budget – cuts made in one place had to be compensated elsewhere. Design and material cutbacks usually meant a compromise in performance or durability.

Those constraints do not apply to modern running shoes. Contemporary lightweight running shoes routinely match – and sometimes exceed – the median lifespan.

While the midsole foam materials have improved by leaps and bounds, a lightweight build is also a result of the upper and outsole. Single-piece engineered mesh uppers help reduce weight, as do thinner outsoles.

Thick outsoles made of superior rubber or flexible geometry are still the most durable kind. At the same time, brands use a combination of improved compounds and clever engineering to reduce weight without sacrificing durability.

For example, the Saucony Endorphin Speed V2 relies on thin, perforated lugs that flex together with the Pebax midsole. The New Balance Beacon 3 has small rubber lugs over what is otherwise an all-foam outsole.

Not long ago, 12 – 13 ounces was the acceptable weight range (refer to our 2011-2012 reviews) for a running shoe. Today, a shoe is deemed heavy if it exceeds 10-ounces.

In nearly all situations, a lighter running shoe is always better. Runners love the NB Fuelcell Rebel or Brooks Hyperion Tempo not just because they’re cushioned and versatile, but also how light and non-distracting they feel during runs.

Trail running shoes are an exception – removing things like the rock plate, a rugged outsole, and protective upper overlays affect the functionality. There are signs of progress though. Both the Brooks Catamount and Skechers GoRun Razor TRL use a lightweight EVA blend for significant weight-related improvements.

As a side note, certain stability shoes cannot function without additional support features. Models like the Brooks Beast 20 or the Saucony Omni 19 have wide midsoles with raised rims and plastic stabilizers. Here, a lighter build will water down the functional proposition.

The bar for the ‘lightest’ tag isn’t the same for every category. It would be unfair to expect a cushioned and mileage-friendly running shoe to weigh the same as a racing flat.

This guide is divided into three categories. The first group contains cushioned running shoes suitable for daily runs to a marathon. All these shoes have a high-volume midsole for long-distance comfort.

The second category has road racers and speed-friendly trainers in them, and the last group has lightweight trail footwear.

The Nike Vaporfly Next% V2 is back on this guide, and the New Balance Rebel V2’s drastic make-over makes it a 7.2-ounce trainer – light enough to be placed on this list.

Category 1: The lightest cushioned running shoes

1) New Balance FuelCell Rebel V2

The recent updates on the New Balance Rebel make it a completely different shoe than the previous model. If you’re interested, here’s our detailed review of the Rebel V2.

Here, the headlining act is the Fuelcell midsole that’s filled with soft and bouncy cushioning. Above it, a deconstructed upper keeps the foot secure in ventilated comfort.

The FuelCell midsole is lightweight, soft, and responsive.

Both the midsole and upper use featherweight ingredients, and the result is a 7.2-ounce shoe that’s versatile enough for everyday runs or tempo training.

Going by some accounts, long-term durability is a potential concern. But as long as the shoe lasts, it will deliver an engaging ride experience.

Weight: 7.2 ounces or 204 grams.

2) Nike Vaporfly Next % V2

This guide wouldn’t be complete without the Nike Vaporfly Next%, would it? Its predecessor – the Vaporfly 4% – was the catalyst for the cushioned racer trend.

The second edition of the Next% has everything that made the first version a commercial success. The midsole contains a deep reservoir of soft and springy ZoomX foam that makes long-distance runs and races less punishing on the feet.

And inside this cushy foam stack is a curved Carbon fiber plate adds delivers the transition-friendly snap. The ZoomX core is protected by front and rear outsole rubber pieces that offer reliable traction.

The Next% uses an incredibly lightweight upper that’s true to size and relatively spacious. The deconstructed upper disappears on the foot during a run.

All of these features are contained within a compact sub-7-ounce form factor.

Weight: 6.9 ounces or 196 grams.

3. New Balance Fresh Foam Beacon V3

A few years ago, the Fresh Foam Beacon burst into the running shoe scene and instantly became a crowd favorite. Its lightweight cushioning made it very versatile. Depending on how one saw it, the Beacon could be used as a daily trainer at moderate paces or the occasional slow day cruiser.

Making things happen was a thick stack of foam that delivered cushioning comfort without the excess baggage.

The single-density midsole was also smooth and supportive, traits that made the Beacon an appealing proposition. Its 6 mm heel-to-toe offset was the sweet spot for most runners.

Now in its third iteration, the Beacon V3 retains the familiar ride quality that made it successful. Also present are the obligatory rubber lugs under the forefoot and heel.

Like the previous Beacons, the upper has a snug and short fit. The exterior receives a few cosmetic details – including the flared heel design that runners have come to either love or hate.

Weight: 8.2 ounces or 232 grams.

4. Brooks Hyperion Tempo

For many years, the Brooks catalog consisted only of comfortable yet clunky products.

The Hyperion Tempo reverses that trend and offers a generously cushioned ride that is also lightweight. And by ‘light’, we don’t mean 10-ounces. The Hyperion weighs just a smidge over 7-ounces. For a brand that sells mega trainers like the Beast and Addiction, that’s quite the turnaround.

If it weren’t for the outsole rubber, the Hyperion could have been lighter. But the extra rubber makes the shoe durable and grippy, so all’s good here.

The 8-mm drop midsole plays a huge role in bringing the weight down. The ‘DNA Flash’ foam is akin to Skechers’ HyperBurst, so the ride quality is similar. The firm cushioning is friendly for long-distance and tempo runs alike.

The comfortable upper sticks to the basics. Interior plushness is all but absent, with foam padding and superfluous overlays kept to a bare minimum.

Our detailed review has all the goods.

Weight: 7.3 ounces or 207 grams.

5. Hoka One One Rincon 3

There are a few reasons why the Rincon 3 weighs less than 8-ounces. This shoe sticks to the original Hoka template by minimizing the use of outsole rubber and leaving most of the cushioning to the EVA foam midsole.

There’s not a lot of layering on the upper either. A single-piece, mono-layer mesh forms the outer shell to create a secure and smooth fit. The tongue and heel are lightly quilted to make things comfortable in the back.

The Rincon 3 is a great example of a mileage-friendly shoe that is also lightweight. It doesn’t cost as much as other maximal Hoka models, so that’s a bonus.

Hoka has updated the Rincon 3’s upper and midsole, but the overall shoe shares a similar character as the V2.

There are some changes, though. The upper now has a racer-like tongue flap (the V2 had a padded tongue), and the mesh has larger in-built vents.

Weight: 7.7 ounces or 218 grams.

6. Saucony Endorphin Speed 2

What we like about Saucony is its ability to make value-added adaptations to an existing cushioning platform. For example, Saucony’s Everun and Pwrrun+ foams were ‘inspired’ by adidas Boost but delivered a ride quality with a distinct cushioning character.

The new Pwrrun PB foam follows a similar path of adaptation. This is Saucony’s new PEBA-based foam that feels markedly different than the likes of Nike ZoomX or Reebok Floatride.

The Pwrrun PB midsole is formed by compression molding a dense cluster of foam globules, and this construction results in a resilient structure. Inside this cushioned midsole is a Nylon plate that makes the transitions snappy.

In short, the Endorphin Speed 2 is an excellent running shoe that delivers an optimal blend of distance-friendly cushioning and tempo character.

All of this is packed into a lightweight, sub-8-ounce package.

Weight: 7.8 ounces or 221 grams.

Category 2: The lightest road racers and fast trainers

1. Reebok Floatride Run Fast 3

The Reebok Run Fast 3 is an under-rated speed trainer that’s akin to a lighter version of the adidas Boston.

If you’re not familiar with either, then know that the Run Fast 3 is a cushioned and lightweight running shoe that bridges the gap between everyday trainers and racing flats. In Reebok’s case, the RF3 resides between the Floatride Energy 3 and the hyper-lightweight Run Fast Pro.

Owing to its PEBA foam midsole, the Run Fast 3 shares more in common with the Fast Pro. Here, a full-length Floatride+ (PEBA) foam is layered together with a firmer EVA rim on top for stability.

The PEBA foam weighs next to nothing, so that creates a weight allowance to accommodate a proper rubber outsole with aggressive lugs. Above the cushioned midsole is a breezy upper that disappears over the foot.

So if you’re in the market for a lightweight semi-racer with a cushioned and supportive ride, it’s hard to go wrong with the Reebok Run Fast 3.

Weight: 7.0 ounces or 198 grams.

2. Skechers GoRun Razor+

If hard-on-your-feet racing flats aren’t your preferred choice of footwear, consider the Skechers GoRun Razor+. The latter isn’t a racing flat – it’s more like a speed-friendly shoe with a firm yet impact-absorbing cushioning.

The Hyper Burst foam midsole provides an optimal mix of cushioning and responsiveness – all within a 6.4-ounce (181 grams) silhouette. The upper fits narrow and somewhat shallow.

Weight: 6.4 ounces or 181 grams.

3. Saucony Kinvara 12

Saucony’s popular trainer with a 4 mm offset returns for the 12th time. It’s also redesigned from the ground up, and shares no parts with the Kinvara 10 and 11. The Kinvara 12 also manages to lose some weight in the process; the new model weighs a comfortable 7.5-ounces.

The midsole gets improved stability because of the wide flare. Nonetheless, the 12 retains the low-offset, medium-soft ride with the Kinvara versatility that everyone loves. The lightweight upper is soft, breathable, and fits securely.

There’s enough cushioning to make runs of most distances comfortable. At the same time, it’s not slow; the new foam is resilient and has ample ground feedback for tempo runs. Our in-depth review tells all.

Weight: 7.5 ounces or 198 grams.

4. New Balance Fresh Foam Tempo

At just under 9-ounces, the Fresh Foam Tempo isn’t the lightest of the bunch. After all, the Tempo shares screen space with many 7 Oz marvels.

And yet, the Tempo manages to hold its own among other lightweights. This is a shoe that’s modeled on the Zante, so it packs a lot of the Z-shoe goodness. The Fresh Foam EVA midsole has a comfortable ride that doesn’t feel lacking under high-speed tempo runs.

The snug-fitting upper is smooth, comfortable, and complements the do-it-all midsole.

Weight: 8.7 ounces or 247 grams.

Category 3: The lightest trail running shoes

1. Brooks Catamount

Cushioning tech from road running footwear is gradually making its way into trail shoes. As a result, outdoor running shoes are getting lighter. The Brooks Catamount is a case in point.

The Brooks Catamount uses the same midsole tech as the Brooks Hyperion, so the hyper-lightweight DNA Flash (Nitrogen-infused EVA foam) allows the Catamount to be cushioned yet versatile.

The shoe weighs just over 9-ounces, and that’s very respectable for a product that has a trail-worthy outsole and rock plate. The aggressive lugs made from the sticky rubber (TrailTack) compound deliver sufficient bite, whereas the plate protects the foot from the pointy rocks and roots.

We’ve heaped praise on the Hyperion Tempo’s cushioning, and the same material equips the Catamount with supportive cushioning for the trails. The firm ride of the 6mm offset midsole has inherent stability for off-road runs with sufficient comfort for high-mileage trail runs.

The upper keeps the weight low by applying protective urethane films over a mesh exterior. The partial sleeve helps keep the debris out and secures the midfoot.

Weight: 9.3 ounces or 264 grams.

2. Skechers GoRun Razor TRL Hyper

Both the Brooks Catamount and Skechers GoRun Razor TRL share a similar ride. In the sense that both the midsoles are based on a lightweight EVA foam blend that is either Nitrogen or CO2 infused.

Without getting caught in the technicalities, these midsoles deliver a cushioned ride in an extremely lightweight package. For example, the Skechers Razor TRL weighs a mere 8-ounces. That’s noticeably lighter than the Catamount, and with good reason.

The Skechers TRL lacks a rock plate and also has an outsole that’s split into multiple pieces. This results in a cushioning upside that makes the ride softer. Also, the 4mm offset of the Hyperburst midsole produces smooth and supportive transitions on the trail.

Thus, trail runners who prefer better ground feel may opt for the Razor instead of Catamount. The downside, of course, is the lack of protection afforded by the Brooks Catamount’s full-length outsole with a rock plate.

Weight: 8.0 ounces or 227 grams.
