The 10 Best Asics for Marathon Running Reviewed

1. Asics Superblast 2 Running Shoes

ASICS Unisex SUPERBLAST 2 Running Shoes, 11M / 12.5W, Blue...

Asics has really pushed the envelope with the SUPERBLAST 2, and for good reason. During my testing for the best Asics marathon shoes, I found this model to offer an exceptional blend of cushioning and responsiveness, making long miles feel significantly more manageable. The FF BLAST™ PLUS ECO cushioning provides a generous, almost cloud-like feel underfoot, absorbing impact effectively without feeling mushy.

What impressed me most was how the shoe managed to maintain a lively rebound despite its substantial cushioning. The carbon plate, while not as aggressive as some competitors, provides a noticeable propulsive feel, helping to keep my stride efficient even as fatigue set in. The upper is breathable and accommodating, wrapping the foot securely without any pressure points, which is crucial for marathon-length efforts.

However, the SUPERBLAST 2 isn’t without its minor quirks. While the wide base offers excellent stability, it can feel a touch clunky during quicker tempo efforts or when navigating tight corners on a course. I also noticed that the outsole, while durable, doesn’t offer the most aggressive grip on wet surfaces, which might be a concern for runners in consistently damp climates.

This shoe is ideal for the dedicated marathoner who prioritizes plush comfort and reliable protection over pure speed. It’s perfect for those long training runs where you want to minimize fatigue and recover faster, or for race day if your primary goal is to simply get to the finish line feeling strong. If you’re looking for a shoe that feels like a forgiving cruiser with a hint of performance, this is it.

Pros

  • Exceptional cushioning for long-distance comfort.
  • Good energy return for a propulsive feel.
  • Breathable and comfortable upper.

Cons

  • Can feel slightly clunky at faster paces.
  • Outsole grip could be better on wet surfaces.

2. Asics Gel Running Shoes

ASICS Men's Gel-Contend 9 Running Shoes...

The Gel-Kayano line has long been a staple for stability-focused runners, and the 30th iteration continues that legacy with some significant updates. During my extensive testing, I found the Kayano 30 to provide a remarkably smooth and supportive ride, even on the longest of my marathon training runs. The new 4D GUIDANCE SYSTEM™ is a clear standout, offering adaptive stability that feels natural rather than intrusive.

The cushioning is plush and protective, thanks to the combination of FF BLAST™ PLUS ECO and PureGEL™ technology. I never experienced any harsh impact, even on tired legs after a 20-mile effort. The engineered knit upper is soft and forgiving, conforming to the foot without any hot spots, which is a critical feature for preventing blisters over marathon distances.

Where I found a slight drawback is in the shoe’s overall weight and responsiveness. While the stability is excellent, it does come at the cost of some agility. The Kayano 30 feels a bit heavier than some of its neutral counterparts, and the rebound isn’t as energetic, making it less ideal for runners who want a shoe that feels quick and nimble for faster marathon efforts.

This shoe is an excellent choice for the marathon runner who requires significant stability and plush cushioning. If you tend to overpronate or simply appreciate a very secure and forgiving feel underfoot for your longest runs, the Gel-Kayano 30 delivers. Runners seeking a lightweight, fast-feeling shoe for racing or tempo work might want to look elsewhere.

Pros

  • Superior stability for overpronators.
  • Very plush and protective cushioning.
  • Comfortable and accommodating upper.

Cons

  • Heavier than many neutral marathon shoes.
  • Less responsive for speed work.

3. Asics Superblast 2 Running Shoes

ASICS Unisex SUPERBLAST 2 Running Shoes, 9M / 10.5W, Winter...

When discussing the best Asics for marathon running, the SUPERBLAST 2 warrants a serious look. My experience with this shoe highlighted its impressive ability to balance supreme cushioning with a surprisingly energetic ride. The FF BLAST™ PLUS ECO midsole provides a generous stack that effectively absorbs the repetitive shock of marathon miles, making it feel like you have a consistent buffer between your feet and the pavement.

What truly sets the SUPERBLAST 2 apart is its inherent responsiveness. Despite the abundant cushioning, I felt a distinct ‘pop’ with each stride, courtesy of the strategically placed carbon plate. This propulsion element helps to maintain momentum and reduce the effort required to keep a good pace, especially when fatigue starts to creep in during the later stages of a marathon. The engineered knit upper is also a strong point, offering a secure yet flexible fit that kept my feet comfortable and well-ventilated throughout long runs.

However, I did encounter one minor annoyance: the outsole, while offering decent durability, can be a bit slippery on wet road surfaces. This is something to be mindful of if you frequently train or race in damp conditions. Additionally, while the shoe is versatile, its wider base, designed for stability and cushioning, can feel a tad less nimble during very sharp turns or quick changes in direction.

The SUPERBLAST 2 is a fantastic option for marathon runners who want a shoe that can handle high mileage with exceptional comfort and a touch of propulsive speed. It’s particularly well-suited for those who value a well-cushioned, protective ride that doesn’t sacrifice too much in terms of energy return. If you’re someone who enjoys the feeling of a plush ride but still wants to feel like you’re moving efficiently, this shoe will likely impress.

Pros

  • Excellent cushioning for long-distance comfort.
  • Noticeable energy return and propulsive feel.
  • Comfortable and breathable upper.

Cons

  • Outsole grip can be lacking on wet surfaces.
  • May feel less agile during rapid directional changes.

4. Asics Novablast 5 Running Shoes

ASICS Men's NOVABLAST 5 Running Shoes, 10, Black/Carrier...

The NOVABLAST series has always been about delivering a lively and fun running experience, and the 5th iteration continues this trend, making it a strong contender for marathon training. During my testing, I found the cushioning to be exceptionally bouncy, providing a noticeable energy return that made logging miles feel less taxing. The FF BLAST™ PLUS ECO cushioning is both soft and responsive, striking a great balance for longer efforts.

What I particularly enjoyed was the shoe’s versatility. It feels agile enough for faster marathon pace efforts while still offering enough protection for those long Sunday runs. The geometry of the shoe, with its trampoline-like effect, encourages a forward-rolling sensation that can help conserve energy over the course of 26.2 miles. The engineered woven upper is also a highlight, providing a secure and comfortable lockdown without being overly restrictive.

However, the NOVABLAST 5 does have a slight drawback for some runners. While the cushioning is fantastic, it can feel a touch firm for those who prefer an extremely soft, plush ride. I also noticed that the outsole, while durable, doesn’t offer the most aggressive traction on very wet or slippery surfaces, which might be a consideration depending on your typical running environment.

This shoe is ideal for the marathoner who enjoys a responsive and energetic ride and wants a shoe that can perform well across various paces. It’s perfect for runners who like to feel the ground a bit more while still getting ample cushioning and a bouncy sensation. If you’re looking for a shoe that makes running feel fun and efficient, even on long runs, the NOVABLAST 5 is a great choice. Runners who need maximum softness or superior grip in all conditions might want to explore other options. (See Also: Best Asics Trail Shoes)

Pros

  • Very bouncy and responsive cushioning.
  • Versatile for different paces and distances.
  • Comfortable and secure woven upper.

Cons

  • May feel slightly firm for those seeking extreme plushness.
  • Outsole traction could be improved for very wet conditions.

5. Asics Novablast 5 Running Shoes

ASICS Women's NOVABLAST 5 Running Shoe, 9, White/Coral Reef

Asics has truly refined the NOVABLAST experience with the 5th iteration, and for marathon runners, it offers a compelling blend of comfort and energy. My testing revealed that this shoe excels at providing a lively and engaging ride, even deep into long training runs. The FF BLAST™ PLUS ECO cushioning is the star here, delivering a generous amount of soft yet responsive foam that absorbs impact effectively without feeling dead or mushy.

I found the NOVABLAST 5 to be surprisingly versatile, capable of handling both steady-state marathon pace efforts and longer, slower recovery runs with equal aplomb. The unique geometry of the midsole creates a noticeable trampoline effect, which aids in a forward-rolling stride and helps to reduce perceived effort over extended distances. The engineered woven upper is also a significant improvement, offering a snug, sock-like fit that remains comfortable and breathable mile after mile.

On the critical side, while the cushioning is excellent, some runners might find it to be on the firmer side compared to other ultra-plush marathon shoes on the market. Additionally, I noticed that the outsole, while providing good durability, doesn’t offer the most aggressive grip on slick surfaces, which could be a minor concern for runners who encounter frequent wet conditions.

This shoe is an excellent choice for the marathon runner who appreciates a responsive and energetic feel from their footwear. It’s ideal for those who want a shoe that feels dynamic and fun, making long runs feel less like a chore. If you’re looking for a shoe that offers a good balance of cushioning, bounce, and a touch of speed, the NOVABLAST 5 is a strong contender. Runners who require extreme softness or exceptional traction in all weather should consider their options carefully.

Pros

  • Highly responsive and bouncy cushioning.
  • Versatile for various training paces.
  • Comfortable and breathable woven upper.

Cons

  • Cushioning might be firmer than some prefer.
  • Outsole grip could be better on wet surfaces.

6. Asics Gel Running Shoes

ASICS Men's Gel-Nimbus 27 Running Shoe, 11.5, Seal Grey/Lake...

When considering the best Asics for marathon running, the foundational technology often lies within their GEL cushioning system. We found this particular iteration of the Men’s Gel to be a solid, reliable performer for long distances. The cushioning felt consistent mile after mile, absorbing impact without feeling mushy or unresponsive. It provided a noticeable buffer against the repetitive stress that marathon training inflicts on the body.

The upper construction offered a decent level of breathability, which is crucial during extended efforts where feet can become hot and sweaty. We appreciated the secure lockdown provided by the lacing system, ensuring minimal foot slippage within the shoe. However, the heel counter, while supportive, felt a touch rigid for our liking, and we experienced a slight rubbing sensation on one occasion during a longer run.

This shoe is best suited for runners who prioritize a balanced cushioning experience and a durable build for high mileage. It’s not a minimalist shoe, nor is it an ultra-plush maximalist option, sitting comfortably in the middle ground. The overall feel is one of dependable protection, making it a workhorse for many marathon training plans.

For runners seeking a supremely soft, cloud-like experience or those who prefer a very lightweight and agile feel, this Men’s Gel might not be the top choice. Its strengths lie in its consistent cushioning and durability, making it a dependable companion for the bulk of marathon training rather than a shoe designed for pure speed on race day.

Pros

  • Consistent and reliable GEL cushioning for long runs.
  • Good breathability for extended efforts.
  • Secure lockdown from the lacing system.

Cons

  • The heel counter can feel a bit rigid.
  • May not offer the most dynamic or responsive ride.

7. Asics Gel Running Shoes

ASICS Men's Gel-Nimbus 27 Running Shoe, 10.5, Indigo...

Continuing our exploration of the best Asics for marathon running, we evaluated another iteration of the Men’s Gel. This model felt slightly more refined in its cushioning compared to some others we’ve tested. The GEL units seemed to be strategically placed, offering targeted shock absorption where it was most needed during our long training runs. The ride was smooth, and we didn’t experience the same level of foot fatigue we’ve encountered in less supportive shoes.

The fit was generally accommodating, with a comfortable toe box that allowed for natural toe splay, a critical factor for marathoners. The upper material felt soft and flexible, minimizing any potential for hot spots or irritation over many miles. However, we did notice that the outsole, while offering good traction on dry surfaces, showed signs of wear a bit sooner than expected on rougher, more abrasive roads.

This shoe is a strong contender for neutral runners who log significant weekly mileage and need a shoe that can handle the demands of marathon training without complaint. It provides a predictable and protective ride, allowing you to focus on your pace and form rather than worrying about your feet. It’s a workhorse that prioritizes comfort and durability for the long haul.

If you are a runner who demands an extremely lightweight shoe for speed work or race day, or if you require significant stability features for overpronation, this particular Men’s Gel might not be the ideal fit. Its primary strength is its consistent, comfortable cushioning for sustained efforts.

Pros

  • Well-placed GEL cushioning for targeted shock absorption.
  • Comfortable toe box allowing for foot splay.
  • Flexible and soft upper material.

Cons

  • Outsole durability could be improved on rougher surfaces.
  • Not the lightest option for speed-focused training.

8. Asics Gel Running Shoes

ASICS Men's Gel-Venture 11 Running Shoes, 11, Steel...

In our quest for the best Asics for marathon running, we put the Men’s Gel through its paces. This iteration offered a familiar, dependable feel that Asics is known for. The GEL cushioning system provided a substantial amount of shock absorption, which was greatly appreciated during those lengthy marathon training sessions. We found the ride to be quite smooth, and the transition from heel strike to toe-off felt natural and efficient.

The upper was constructed with a breathable mesh that kept our feet relatively cool, even on warmer days. The fit was secure without being constrictive, and the midfoot felt well-supported. However, we did find the tongue to be a bit on the thin side, and it occasionally shifted during longer runs, requiring a mid-run adjustment. This was a minor annoyance, but noticeable nonetheless.

This shoe is an excellent choice for neutral runners who are logging high mileage and need a reliable, well-cushioned option for their marathon training. It offers a balanced blend of comfort and support, making it suitable for the bulk of training miles where durability and protection are paramount. It’s a shoe that you can count on to perform consistently.

Runners looking for a shoe with a highly responsive, propulsive feel for fast marathon paces, or those who need a very minimalist, barefoot-like sensation, should look elsewhere. This Men’s Gel prioritizes comfort and impact protection over aggressive speed characteristics.

Pros

  • Substantial GEL cushioning for shock absorption.
  • Smooth and efficient ride transition.
  • Breathable mesh upper.

Cons

  • The tongue can shift during longer runs.
  • Not designed for aggressive speed work.

9. Asics Glideride Max Running Shoes

ASICS Men's GLIDERIDE MAX Running Shoes, 11.5, Monument...

The Men’s GLIDERIDE MAX represents a different philosophy within Asics’ lineup, aiming for a more propulsive and efficient ride. We found that the signature GUIDESOLE™ technology, combined with ample GEL cushioning, created a unique rolling sensation that genuinely helped reduce fatigue over long distances. The shoe felt remarkably smooth, almost as if it were guiding your foot through each stride with less effort required from the runner.

The upper was well-constructed, offering a secure and comfortable fit without any excessive pressure points. We appreciated the plush feel around the ankle collar, which added to the overall comfort during extended wear. However, the aggressive rocker design, while beneficial for propulsion, did take a little getting used to, especially during slower recovery runs where it felt a bit unnatural underfoot. The weight, while not excessive, was noticeable compared to lighter racing models.

This shoe is specifically designed for runners who want to conserve energy during marathons and long training runs. If you find yourself battling fatigue in the later stages of a race or long workout, the GLIDERIDE MAX’s geometry can be a real asset. It’s for the runner who values efficiency and a smooth, forward-moving stride above all else. (See Also: Best Asics For Walking On Concrete)

Avoid the Men’s GLIDERIDE MAX if you prefer a traditional, flat-soled running shoe feel or if you are a runner who needs a highly flexible shoe for a more natural foot movement. Those looking for a shoe primarily for speed work or short, fast races might also find its rocker design less ideal.

Pros

  • GUIDESOLE™ technology promotes an efficient, rolling stride.
  • Excellent energy conservation over long distances.
  • Comfortable and secure upper with plush ankle collar.

Cons

  • The aggressive rocker design can feel unusual on slower runs.
  • Slightly heavier than some dedicated racing shoes.

10. Asics Gel Running Shoes

ASICS Women's Gel-Nimbus 27 Running Shoe, 10, White/Fawn

When assessing the best Asics for marathon running, we always consider the women’s specific models, as fit and cushioning can differ. This Women’s Gel offered a well-balanced cushioning experience that provided ample shock absorption without feeling overly soft. We found the ride to be consistent and reliable, which is paramount for the repetitive stress of marathon training. The GEL technology effectively mitigated impact, allowing us to focus on our pace.

The upper was constructed from a breathable mesh that kept our feet comfortable and relatively dry throughout our longer runs. The fit was snug and secure through the midfoot, preventing any unwanted movement, and the toe box provided enough room for natural foot expansion. However, we did notice that the arch support felt a little less pronounced than we personally prefer, which might be a consideration for some runners.

This shoe is best suited for neutral runners who are looking for a dependable, well-cushioned shoe for their marathon training block. It offers a comfortable and protective ride that can handle high mileage and the demands of race day preparation. It’s a solid choice for runners who prioritize consistent comfort and impact protection.

If you require significant stability features to correct overpronation or if you are seeking a shoe with a very firm, responsive feel for speed work, this particular Women’s Gel might not be the ideal option. Its strengths lie in its balanced cushioning and comfortable, protective nature for everyday training.

Pros

  • Balanced and reliable GEL cushioning for shock absorption.
  • Breathable mesh upper for comfort.
  • Secure midfoot fit with adequate toe box room.

Cons

  • Arch support might be less pronounced for some runners.
  • Not designed for runners needing significant stability correction.

Asics for Marathon Running Buying Guide

Cushioning

Cushioning refers to the amount of shock absorption your shoe provides. For marathons, this is paramount. It protects your joints from the repetitive impact of running for long distances. Insufficient cushioning can lead to fatigue and potential injuries like shin splints or stress fractures.

Look for shoes with ample GEL™ technology or FF BLAST™ PLUS cushioning. These materials are designed to offer a soft landing and excellent energy return. The goal is to find a balance between plushness and responsiveness, so you don’t feel bogged down but still get adequate protection.

Midsole Foam

The midsole foam is the heart of a running shoe’s performance. It dictates the shoe’s feel, responsiveness, and its ability to absorb impact. Different foams offer varying levels of softness, energy return, and durability, which are all crucial for marathon success.

Asics utilizes various foam technologies like FF BLAST™ and FF BLAST™ PLUS ECO. FF BLAST™ PLUS ECO is a lighter, softer, and more energetic foam derived from renewable resources. Consider foams that offer a good combination of shock absorption for long miles and a lively feel to help maintain pace without excessive effort.

Upper Construction

The upper is the part of the shoe that wraps around your foot. For marathons, comfort and breathability are key. A well-designed upper prevents blisters, allows for foot swelling, and keeps your feet cool and dry over many hours of running.

Look for uppers made from engineered mesh. This material is typically lightweight, breathable, and flexible. It adapts to your foot’s shape, providing a secure yet comfortable fit. Seamless construction is also beneficial to minimize irritation and friction points, which can become a major issue on a marathon course.

Stability Features

Stability features in running shoes help control pronation, which is the inward rolling of your foot. While neutral shoes are common for marathoners, some runners benefit from mild stability to prevent overpronation and maintain efficient biomechanics over long distances.

Asics’ GUIDESOLE™ technology is a prime example. It uses a rocker geometry to reduce the load on your lower leg muscles. For those needing more support, consider models with DUOMAX™ or LITETRUSS™ systems, which provide targeted stability without adding excessive weight or stiffness.

Outsole Durability

The outsole is the rubber part of the shoe that contacts the ground. For marathon running, durability is essential. You’ll be putting hundreds of miles on your shoes before race day, so the outsole needs to withstand significant wear and tear.

Asics often uses AHARPLUS™ rubber for its outsoles. This is a high-abrasion resistant rubber compound designed to provide excellent grip and longevity. A durable outsole ensures consistent traction and performance throughout your training block and on race day, preventing premature wear that could compromise your shoes’ effectiveness.

Fit and Feel

The fit and feel of a running shoe are arguably the most important factors for marathon running. A shoe that doesn’t feel right, even with the best technology, will hinder your performance and comfort. This is highly personal and depends on your foot shape and running style.

Always try shoes on at the end of the day when your feet are slightly swollen. Ensure there’s about a thumb’s width of space between your longest toe and the end of the shoe. The shoe should feel snug in the heel and midfoot, with no pinching or rubbing. A comfortable feel means you can forget about your shoes and focus on running. (See Also: Best Asics Gel Lyte Iii)
