ASICS Superblast 3 — what reviewers say
Ride profile: maximal cushion , soft_plush feel , high energy return , neutral stability , moderate rocker.
-
One of the best long-run shoes on the market thanks to its soft FF Blast foam and great lockdown, though this version's outsole durability is a step down from the Superblast 2.
Ride:Super soft, lightweight, and comfortable for 20K-30K long runs; can feel a little unstable at faster paces/tight corners.
In their words: "amazing for those long runs" · "a real shame about the durability"
-
A soft, comfortable shoe Fordy still takes out for 12-15 mile runs, but which he doesn't consider suited to his very longest long-run mileage.
Ride:Soft, cushioned ride; comfortable for mid-length runs but not rated for his very longest miles.
In their words: "if you like a soft shoe"
-
An impressively light max-cushion trainer that shines on long, steady marathon-pace efforts, but several testers found it softer and 'mushier' than expected, less specialized than the Superblast 2, and not clearly worth its higher price over the Novablast 6.
Ride:Softer, more compressive, and more consistent underfoot than the Novablast 6 thanks to the full-length FF Leap top layer, giving a smooth heel-to-toe roll well suited to marathon-pace long runs — but a couple of testers found it 'mushy' at slower paces and less versatile for faster work than the previous Superblast 2.
Fit:True to size with a roomy toe box, though slightly less heel-collar padding than the Novablast 6.
In their words: "much softer, more compressive, more highly cushioned" · "a little bit mushy" · "lost some of its upper pace edge"
-
Kofuzi calls the Superblast 3 one of the best shoes in its class -- lighter than the Neo Vista 3, capable of both daily training and picking up the pace -- and says it's his preferred option overall despite the $210 price.
Ride:Squishier, airier, bouncier FF Blast top foam evened out by a firmer daily-training bottom layer; noticeably lighter than the Neo Vista 3 and better at picking up the pace.
In their words: "one of the best in its class" · "relatively feather weight"
ASICS Megablast — what reviewers say
Ride profile: maximal cushion , neutral stability .
-
The Run Testers name the Megablast their top pick for a faster daily trainer — a pricey, plateless max-stack shoe with FF Turbo Squared foam that stays stable as legs tire and excels at speed sessions and progression runs.
In their words: "sits at the top of the impressive pile" · "plate-less shoe that is built for performance" · "excels for the faster stuff"
-
One of the standout shoes in the range — an extremely durable, fast, non-plated foam shoe well suited to marathon racing, let down only by a shallow toe box.
Ride:FF Turbo Squared midsole gives a super snappy, fast ride with your feet 'disappearing' underneath you; excellent durability, reportedly lasting near 1,000 km.
Fit:Toe box is a little shallow, which caused some upper irritation on the reviewer's first pair.
In their words: "your feet just disappear underneath you" · "one of the greatest of all time"
-
Fordy's top pick overall for a shoe you could take from long training runs into race day itself — expensive, but he calls it phenomenal for marathon-goal-pace work, with the caveat that a poor fit can rub the little toe.
Ride:Phenomenal, race-day-capable ride Fordy uses specifically for marathon-goal-pace work within long runs.
Fit:Runs narrow through the toe box — a poor fit can rub the little toe.
In their words: "the best shoe if we're really honest" · "phenomenal as a long run shoe"
-
Praised as a great, extremely durable shoe and a slightly lighter alternative to the Superblast 2, but passed over for the two-shoe rotation pick due to its more aggressive ride and higher price tag.
Ride:Slightly lighter but noticeably more aggressive-riding than the Superblast 2.
In their words: "even though it is crazy durable" · "a much more aggressive model"
