ASICS Megablast Review: Audited Plate-Free Super Trainer
Disclosure: TrainingPlan has not hands-on tested this exact model. This research-based review uses exact ASICS product material, an ASICS technical brochure, and independent exact-model evaluations. No Amazon US listing is currently verified.
Quick Verdict
ASICS Megablast is a current unisex high-stack road trainer released in September 2025. ASICS lists an 8mm drop, 230 grams or 8.1 ounces, and a MSRP: $225 price. Its technical brochure gives 46mm at the heel and 38mm at the forefoot. Doctors of Running publishes 45/37mm and measured 7.9 ounces in men's US 9, a small method and sample difference that is explicitly retained.
The full-length FF TURBO SQUARED midsole has no plate. Megablast is designed to combine high cushioning with low mass and a responsive ride across daily, long, and faster sessions. Its strengths are range and rebound; its limits are price, height, standard-only width, and a fit that not every foot will accept.

What Changed
The previous catalog used 47/39mm, 8.5/7.3 ounces, and MSRP: $200. The exact US page and ASICS technical brochure support 46/38mm, an 8.1-ounce unisex reference, and MSRP: $225. Using 8.1 for both catalog gender slots communicates one unisex specification; it does not claim two separately weighed samples.
The copy now names FF TURBO SQUARED and confirms there is no plate. It also records the one-millimeter independent stack difference rather than presenting a false consensus. The former Amazon URL was removed pending an exact MEGABLAST title and ASIN check.
Ride and Intended Use
FF TURBO SQUARED is designed for high rebound with enough substance to support a very tall platform. Independent reviewers describe a lively, springy ride that can move from easy pace into tempo work without a plate dictating toe-off. The broad midsole and ASICSGRIP outsole add control, but the shoe still feels tall.
Daily mileage, steady long runs, progression sessions, and moderate workouts are its natural range. It can cover races for runners who prefer an unplated shoe, but the 46mm brand heel geometry sits outside conventional elite road-race limits. See choosing running shoes for role-based selection.
Fit and Sizing
The engineered woven upper is unisex and available only in standard width. Reviews report generally true-to-size length with a secure, sometimes snug midfoot and toe box. A low-volume or tapered fit can be efficient at speed but unsuitable for broad feet.
Try it late in the day and at running pace. Confirm that the upper holds the foot without toe compression and that the heel does not lift. The ASICS Superblast 2 is a useful same-brand reference, but its last and foam stack are not identical.
What Works Well
Low mass relative to stack is the main achievement. An 8.1-ounce reference at 46/38mm gives substantial protection without the weight normally associated with maximum cushioning. Plate-free construction also preserves a smoother, less rigid transition than many super trainers.
ASICSGRIP rubber supports wet-road traction and durability. The shoe's broad pace range can simplify a rotation for runners who genuinely enjoy a tall, energetic platform.
Tradeoffs
MSRP: $225 is expensive for a trainer, only standard width is listed, and the platform reduces ground feel. Tall soft shoes can feel unstable on turns or uneven pavement for some runners. A lively ride can also be excessive for genuinely slow recovery running.
High cushion is not a medical benefit. The shoe should be chosen for comfort and mechanics, not injury prevention. Inspect outsole, foam alignment, and upper hold using when to replace running shoes.
Who Should Consider This Shoe
Consider Megablast if you want one premium, plate-free shoe for daily mileage, long runs, and controlled speed, and if a tall standard-width unisex fit works. It particularly suits runners who dislike carbon stiffness but still want modern foam rebound.
Who Should Look Elsewhere
Look elsewhere for low stack, broad sizing, maximum stability, budget value, or legal elite racing geometry. The ASICS GT-2000 13 provides guidance and lower height; ASICS Metaspeed Sky Tokyo is the specialized race option.
Cross-Brand Comparison
Compared with Topo Specter, Megablast is taller, more expensive, and built from a single premium foam rather than an EVA carrier and insert. Compared with Brooks Glycerin Max 2, it is much lighter and livelier but less calm at recovery pace.
Same-Brand Comparison
Superblast 2 uses layered foams and is also a high-stack unplated trainer. Sonicblast adds an ASTROPLATE. Metaspeed uses carbon for racing. Megablast sits at the lightest and most energetic end of ASICS training rather than replacing every BLAST model.
Value
MSRP: $225 is justified only if its broad pace utility replaces multiple roles. Runners who use it solely for easy miles can obtain comfort for less. Exact identity matters because SONICBLAST and SUPERBLAST are different constructions. No affiliate link is currently verified.
Final Verdict
ASICS Megablast is accurately a 46/38mm, 8mm-drop, 8.1-ounce unisex super trainer with plate-free FF TURBO SQUARED foam. It delivers remarkable cushion-to-weight and pace range, balanced by high price, tall geometry, and limited fit choice.
Key Takeaway
Megablast offers unusually low mass and lively plate-free cushioning at a very high stack, with premium price, standard-only width, and reduced ground feel.
