ASICS MEGABLAST
Springy, ultra‑cushioned daily trainer with race‑like pep and narrow fit — premium price, try before buying.
The ASICS MEGABLAST is a cheekily explosive daily trainer that turns plod into pep with its FF TURBO² A‑TPU midsole, delivering a bouncy, race‑adjacent ride for runners chasing speed and long‑run comfort. Built for tempo days and marathon miles, it pairs 45/37mm stack cushioning and an 8mm drop with a surprisingly feather‑light ~230g feel. Experts and users praise the foam’s longevity and the ASICSGRIP outsole traction, though many flag a narrow, low‑volume upper that clashes with wider feet. At a premium $225 tag, value hinges on fit and use-case—durability and performance drive its recommendation.

Runner's World UK contributor Ali Ball praises the ASICS MEGABLAST as an exhilarating, hugely fun daily trainer that injects bounce and speed into easy runs and race efforts thanks to its new FF Turbo Squared A‑TPU midsole. She highlights its lightweight, breathable, racer-like upper and true-to-size fit (with a slightly narrower toe box), noting the shoe feels livelier and more responsive than the Superblast 2 despite sharing the same stack and drop. Ball tempers enthusiasm with clear reservations about a wobbly, less structured ride—especially for runners who prioritize stability—and uncertainty around long-term durability at the £210 price. Overall she calls it one of her favorite running shoes of 2025 for its energetic ride and versatility, while urging cautious buyers to consider stability needs and await more mileage data on foam longevity.
By Ali Ball
Run (Outside Online) praises the Asics Megablast as a rare, near-perfect jack-of-all-trades: a max-cushioned trainer that somehow marries 45 mm of lively A‑TPU foam with an unexpectedly light, snappy ride. The reviewer sounds genuinely excited—calling the midsole “poppy,” “highly reactive,” and praise-worthy for keeping cadence from easy paces up to 5-minute miles—while noting clear, measured caveats about the upper fit (generous toe box, baggy for narrow feet) and the $225 price. Unique insights include the foam chemistry (FF Turbo Squared’s claimed gains over FF Turbo Plus), the unorthodox single-density, unplated midsole that preserves versatility, and the unusual pleasant toe‑tap sound versus typical “slap.” Overall the tone is enthusiastic and confident: the Megablast is presented as a versatile, performance-minded daily trainer many runners could happily use for nearly every run.
By Cory Smith
Canadian Running praises the ASICS Megablast as a lightweight, high-stack daily trainer that pairs well with the faster Sonicblast for speedwork and racing. The reviewer is upbeat and appreciative, highlighting the Megablast’s nearly translucent engineered-mesh upper, comfortable heel padding, secure lacing, and the new FF Turbo Squared cushioning that delivers plush responsiveness without feeling unstable. They note the Sonicblast’s added pep from a Peba propulsion plate and its breathable knit upper, while cautioning both shoes are optimized for dry, smooth roads. Practical recommendations are given—use the Megablast for everyday miles and the Sonicblast for harder efforts or 5K–half-marathon racing, or choose the more versatile Megablast if you prefer one pair. The tone is positive and confident, emphasizing durability, modern styling, and a tester’s intent to keep them in rotation.

RunRepeat's Carlos Sánchez highlights the ASICS Megablast as a near‑dominant super trainer, praising its remarkable energy return, exceptional shock absorption, feather‑light weight, and premium materials that make it versatile for daily training, tempo work, and many race scenarios — especially for runners who prefer a plate‑free, highly bouncy ride. He backs claims with lab numbers (e.g., 73% energy return, 45.1 mm heel stack, 160/144 SA shock absorption) and notes outstanding grip from ASICSGRIP rubber, precise fit data, and impressive cold‑temperature foam resilience. Criticisms are candid but measured: the Megablast is very expensive, has limited outsole rubber coverage, a stiff bend that may feel disconnected to ground‑sensitive runners, and some durability concerns in the upper/toebox. Overall Sánchez is enthusiastic and impressed, calling it a top pick for marathoners and versatile runners while acknowledging price and ride‑preference trade‑offs.

RTINGS.com praises the ASICS MEGABLAST as a lively, max‑cushion trainer that pairs an impressively light, thin upper with a very bouncy FF Turbo² midsole. The reviewers deliver an upbeat, largely positive tone: they highlight exceptional protection—especially in the heel—strong energy return, and versatility across daily miles, long runs, and uptempo sessions, while noting it isn’t as propulsive or snappy as plated super shoes. Criticisms are measured: the soft, tall stack can feel a bit wobbly for some runners and less suited to short, fast races, and the thin upper may struggle to lock down narrow feet. Unique insights include detailed comparisons within ASICS’ BLAST family (MEGABLAST as the playable, lighter counterpart to SUPERBLAST and SONICBLAST) and concrete specs on stack heights and weight that support the reviewers’ practical, data‑driven conclusions.

Peter Stuart and Sally Reiley praise the ASICS MEGABLAST as a remarkably light, bouncy, and fun super‑trainer that delivers a high, energetic ride from the new FF Turbo Squared foam while remaining surprisingly versatile across easy runs, long miles, and quicker paces. They highlight standout positives—exceptional rebound and cushioning despite a 45 mm stack, low weight for the category, secure heel hold, sticky outsole traction, and a smooth, rolling ride that improved after break‑in—while noting concrete drawbacks: a minimal, unlined upper that can feel rough and tight in the toe box (potentially problematic for wider feet), limited tongue padding causing occasional lace bite, some softness-related stability tradeoffs, and a premium $225 price for an unplated trainer. Unique insights include detailed midsole measurements (softer, bouncier, lighter FF Turbo Squared) and multi‑tester real‑world mileage (Sally’s 120 miles) supporting the shoe’s lively, enduring character.
By Peter Stuart and Sally Reiley
Women’s Running's Laura Fountain praises the ASICS Megablast as a lively, max‑cushion daily trainer that combines long‑run comfort with race‑day energy. She highlights the ultralight 224 g build, 45/37 mm stack and new FF Turbo Squared foam for a snappy, propulsive feel that’s 32–33% bouncier and noticeably softer than previous Turbo foams. Tested on easy 6‑mile runs and interval sessions, the shoe delivered surprising stability from its wide base, excellent grip from the ASICSGRIP outsole, and a secure, performance‑oriented fit—though narrower‑footed runners may find the upper roomy. Her only clear downside is the £210 price for a non‑plated trainer, but overall she recommends it for runners seeking a cushioned, responsive shoe—especially heel‑strikers who want a softer, speedy option.
By Laura Fountain
Tom's Guide praises the Asics Megablast as a standout, highly versatile running shoe that delivers a bouncy, lightweight, and stable ride across recovery runs, long tempos and fast intervals. Nick Harris-Fry clearly enjoyed the shoe — calling it “brilliant” and noting excellent durability after 100 miles, a lively FF Turbo Squared midsole, breathable upper, and confident grip on light trails. That enthusiasm is tempered by repeated, practical reservations about price and agility: at $225/£210 it’s significantly more expensive than several capable alternatives (Adidas Adizero Evo SL, New Balance Rebel v5, Puma Velocity Nitro 4) that offer comparable value, and it isn’t as nimble as leaner speed shoes. In short, the reviewer loves the Megablast’s all-round performance and comfort but stops short of an unqualified recommendation because the premium cost makes more affordable, nearly as-good choices attractive.
By Nick Harris-Fry
220 Triathlon's Edward Pickering highlights the ASICS MEGABLAST as an exuberant, fun-to-run trainer that injects spring and speed into workouts. He praises the FF Turbo Squared midsole, 45mm heel stack and 8mm drop for a propulsive, bouncy ride that produced lower heart rate and faster splits on long runs, and notes the lightweight woven upper, secure serrated laces and overall race-capable feel. Criticisms are minor but practical: the shoe comes in only one width and felt slightly tight on Pickering’s mildly wide feet, risking pressure at the little toe. At £210/$225 it’s a premium pick best reserved for key fast sessions or A/B race use, yet its lively character and clear performance gains make it an easy recommendation for runners who prioritize responsiveness and fun.
By Edward Pickering
Hannah Singleton from GQ highlights the ASICS Megablast as an electrifying, bouncy supertrainer that excels at tempo runs, sprints, and race-pace efforts. She praises its A-TPU foam for delivering a carbon‑shoe-like propulsive feel without a plate, its light, breathable upper, secure sawtooth laces, and surprisingly stable ride for fast treadmill work. At the same time she cautions the shoe isn’t forgiving at slow paces—wide-footed or slow runners may experience pinching and shin pain until the shoe breaks in—and the engineered mesh runs narrow and can feel too airy in cold weather. Unique insights include a detailed break-in narrative (painful easy runs that eased after many miles) and a persistent indoor squeak. Overall, Singleton frames the Megablast as a fun, confidence‑boosting go‑fast shoe that’s highly effective for faster runners but less versatile for slower or wide-footed users.
By Hannah Singleton
Prevention’s Caitlin Carlson praises the ASICS Megablast for delivering an unusually lively, lightweight ride that blends marathon-ready cushioning with surprising responsiveness. She’s enthusiastic about the new Turbo Foam: at 7.8 oz the shoe feels markedly lighter than her Gel‑Nimbus while offering 2.5 mm more stack and a distinctly bouncy, energetic push that translated to both long training runs and shorter tempo efforts—and even city walking tours. She notes practical strengths (comfortable fit for slightly wide feet, good wet‑pavement traction, and an 8 mm drop helpful for Achilles/plantar‑fascia concerns) alongside clear caveats: a high $225 price, limited color choices, and no wide sizing yet. Her unique insight is that the Megablast approaches the speed feel of carbon‑plate racers despite being a cushioned trainer, making it a compelling, if premium, all‑around option.

RUN SDJRUN SDJ praises the ASICS MEGABLAST's feather-light weight, FF TURBO² responsiveness, smooth rocker, and surprising grip after 150 km across Lanzarote heat and icy UK runs, but warns its very neutral platform aggravated his flat-arch knee pain—now reserved for intervals/tempos, not long marathon efforts.

Ryan’s Running ReviewsRyan’s Running Reviews compares the ASICS MEGABLAST to the Superblast 3, praising the Megablast’s lighter weight (8.1oz) and full FF Turbo² midsole while noting the Superblast’s taller stack (46.5mm) and mixed-foam setup.

Good Good RunningGood Good Running highlights the ASICS MEGABLAST’s standout versatility — lightweight, bouncy midsole and secure, racy fit make it suitable from fast reps to long easy runs.

Overall, the reviewer strongly recommends the Megablast as an all-purpose trainer: a reliable, fun shoe you can reach for on most runs despite a minor fit caveat.
Brandon Caldwell | Strength & RunningBrandon Caldwell | Strength & Running finds the ASICS MEGABLAST impressively cushioned and bouncy after a week of testing, calling it “super responsive” and more supportive than many trainers — almost like it’s plated.

Overall recommendation: Positive and enthusiastic — he views the MEGABLAST as a great, versatile trainer for easy, tempo, and some long runs, praising comfort and responsiveness while noting mild surprise at its firmness; recommends buying it alongside his go-to SL rather than replacing it.
Emily HellerEmily Heller highlights the ASICS MEGABLAST's abundant FF Turbo 2 foam, praising its plush cushioning, lively rebound, and greater nimbleness versus the Superblast—she notes it felt cushy on a 5.4-mile run and promising for long miles and faster efforts.

She candidly notes early pinky-toe blisters, dislikes the colorway, and flags the price as high for some buyers. Overall, Katecanrun strongly recommends the Megablast as a single, do-it-all trainer that feels like a plated shoe without the plate—worth the cost if you value cushioning, responsiveness, and durability despite minor fit and aesthetic downsides.
วินชยุต🏃🏻➡️🍜วินชยุต🏃🏻➡️🍜 notes he's logged 130 km in the ASICS MEGABLAST and genuinely likes the foam’s energetic, non–energy-sapping ride that holds its feel from kilometer 1 to 21. He calls out two clear downsides: yellowing foam and persistent rubbing at the outer pinky toe, and the shoe isn’t as soft/cushy as some runners prefer. Overall, he leans positive—appreciative of the MEGABLAST’s responsiveness and long-run stability but not an unconditional endorsement; he recommends it for runners who want a springy, durable trainer while warning those seeking plush softness or a perfect toe fit to try alternatives.

Overall, Carlos views the Megablast as a fun, explosive option for quality sessions, fast long runs, or even “illegal” marathon use — a strong recommendation for runners who prioritize bounce and lightness and accept some tradeoffs in stability and fit.

Amazon reviewers praise the ASICS MEGABLAST for its lively, highly cushioned midsole and energetic rebound that propels runs, making it a favorite for long runs, recovery days, and tempo efforts. Many runners highlight the shoe’s light weight despite substantial foam, noting a bouncy, responsive ride and good support for heavier runners. Reviewers also call out excellent ventilation and a secure tongue-and-lace system that reduces hotspots. Opinions diverge on fit: some find the MEGABLAST true to size, while others report a snug toe box or low forefoot volume and recommend trying a half size up if you have wider feet. A few users compare it unfavorably to other models in the Blast line, but several emphasize durability and long-lasting cushioning. Value impressions split as well—some consider the price justified by comfort and performance, while others label it pricey relative to alternatives. Overall, Amazon customers recommend the shoe for runners seeking cushioned, responsive daily trainers and long-distance comfort, with fit being the main caveat to check before committing.

Reddit consensus on the ASICS Megablast is mixed-positive: users widely praise the midsole—A‑TPU/FF Turbo‑squared foam—as bouncy, energetic, and durable, delivering strong energy return, protection on long runs, and excellent wet traction. Many find it versatile for tempos and long runs and note exceptional longevity. Criticisms focus on the upper: low vertical volume, narrow/tapered toe box, finicky lockdown and abrasive/hard heel pull that can cause blisters; some report instability at very slow paces or on tight corners. Upgraders often seek Megablast’s improved bounce over Superblast, while new shoppers are cautioned to size and test fit carefully.

ASICS’ latest trainer arrives as a bold statement from a brand known for engineering‑first running shoes—positioned as a premium, unplated “super‑trainer” that aims to marry race‑like pep with marathon‑ready cushioning. Built to propel tempo days, long runs and even race efforts, it’s defined by its full‑length FF TURBO² A‑TPU foam, a tall 45mm heel / 37mm forefoot stack, and a snappy 8mm heel‑to‑toe drop that encourages a forward roll. Expect sticky road grip from ASICSGRIP rubber and targeted longevity via an AHAR heel plug, plus a feather‑light feel at around 230 g (men’s US 9). The tradeoff is a minimalist, low‑volume upper that rewards a snug, performance fit—ideal for faster, fit‑focused runners rather than casual walkers. Read on: we’ll unpack energy return, stability, traction, fit and feel so you can decide whether this is your one‑shoe quiver or a specialist’s secret weapon.
Midsole cushioning and energy return (FF TURBO²)
If you want to feel spring in every stride, the FF TURBO² midsole is the show-stealer: aliphatic A‑TPU delivers a 33% bump in bounciness and a noticeably softer late-stage ride, translating to lively tempo sessions and forgiving long miles. Lab numbers and reviewer mileage confirm the high energy return and sustained pop after 100–300 miles, though a few testers flagged a firmer break-in. This foam makes hard workouts feel zippier and recovery runs less punishing, earning genuine praise as a raceable, unplated racer-feel near the end.
Outsole traction and durability (ASICSGRIP, AHAR heel plug)
The ASICSGRIP outsole plus AHAR heel plug smartly mixes sticky road traction with targeted durability, so wet runs and high-mileage weeks don’t shred the rubber fast. Reviewers report consistent grip across conditions and very little midsole packing even after extended miles, supporting the shoe’s durability claims. Limited rubber coverage in places raises cautious notes on longevity for abrasive surfaces, but overall the outsole setup delivers reliable traction and purposeful wear resistance that backs the midsole’s longevity. Good grip, smart durability trade-offs.
Rocker geometry and responsiveness (unplated design)
The late-stage rocker and wide forefoot midsole (117.9mm) give a smooth, energy-conserving roll that feels surprisingly propulsive for a non‑plated shoe—think snappy daily trainer rather than a rigid racer. The unplated FF TURBO² keeps flex and versatility across paces, delivering a plate-like pep without stiffness, though very slow paces can expose a slightly unstable feel for some. This geometry is a core reason the shoe doubles as tempo/race-capable and long-run comfort, offering responsive transitions with playful rebound.
Weight
Despite its max-cushion profile, the Megablast stays featherlight—around 230g (men's US 9)—so the lofty stack doesn’t feel like lead on fast efforts. Testers praise how the low mass amplifies the FF TURBO²’s pop and reduces fatigue on long runs, making it feel more like a spirited trainer than a lumbering max shoe. The lightweight build is a genuine advantage for tempo days and marathon training, delivering high-stack comfort with race-friendly nimbleness near the end.
Stack height and heel-toe drop
At roughly 45mm heel / 37mm forefoot with an 8mm drop, the Megablast stacks serious protection into a surprisingly light package, smoothing impact and promoting a forward roll without a stiff plate. That tall stack gives marathon cushioning and shock absorption (noted in lab SA figures), but the high profile can feel tippy at very slow paces for some runners. For tempo-to-long-run duties it’s a boon—offering plush protection and a rocker-aided transition that keeps legs fresher later. Excellent for distance, watch the slow-pace wobble.
Upper construction and fit
The translucent engineered mesh looks racer-sleek and breathes brilliantly, but the minimalist build creates a low forefoot volume and narrow, tapering toe box that trips up wider feet—try a half-size up or test fit. A gusseted tongue and secure lacing reduce hotspots for many, yet some users reported abrasive tongue/heel pressure and a plasticky feel until broken in. Experts and users agree: the upper is performance-focused and airy, but fit quirks are the most common real-world caveat.
Conclusion
Think of this as a spirited handshake: the FF TURBO² midsole gives a spring that turns hard miles into playful strides, while the 45/37mm stack and 8mm drop protect your legs without feeling ponderous. The ASICSGRIP outsole and AHAR heel plug mean grip and mileage aren’t afterthoughts. The airy, low‑volume upper rewards a performance fit but will frustrate wider feet. The late‑stage rocker delivers surprising forward roll and a plate‑like pep, and at roughly 230 g it never drags on tempo days. If you chase speed with comfort, this shoe excels; if you need roomy toe boxes or rock‑steady slow‑pace stability, consider alternatives. In short: an energizing, high‑mile trainer that asks you to value bounce over plushness, snappy transitions, sticky road grip, long‑haul durability, racy, low‑volume fit, wide‑foot caution, featherlight mass, and rocker‑driven propulsion —a confident pick for runners who want pep without a plate.
