Our verdict
The ASICS Superblast 3 is the most versatile running shoe ASICS makes: a towering, plateless super trainer that does the job of three or four shoes in your rotation. With a 45.8mm heel and 37.7mm forefoot it sits right at the World Athletics stack limit, yet at 235g it stays light enough to pick up the pace when you ask. There is no carbon plate here, and that is the whole point. This is soft, bouncy foam doing the work, so you get a springy daily training shoe that will still hang on through a tempo session or a half marathon. We rate it as one of the best do-it-all trainers on the road right now. It is not a dedicated marathon shoe and it is not cheap at £190, but if you want a single pair that covers easy miles, long runs and race-pace efforts without switching, the Superblast 3 is about as good as it gets. Bigger runner, one shoe, most of the week: this is the one.

Extra information
Fit & sizing
The Superblast 3 comes up true to size for most runners, so order your usual ASICS number. The fit is a touch on the snug side through the midfoot, which is what you want in a shoe this tall: it keeps your foot planted on a high stack and stops any wobble when you lean into a turn. The toe box is medium width, roomy enough for longer runs and mild swelling but not what we would call wide. If you have a broad forefoot or size up for ultra distances, try before you commit, because there is no wide version. Heel hold is secure with a moderately padded collar that locks the rearfoot without pressure. Midfoot lockdown is good once you snug the laces, though the tongue is fairly thin so ease off if you feel any lace bite. For most runners, take your normal size and go. Half sizes are worth trying on if you are between sizes and want extra toe room for marathons.
Performance breakdown
Ride & feel
This is where the Superblast 3 earns its reputation. The ride is soft and springy without being unstable, a rare balance at this stack height. At easy pace it feels protective and forgiving, soaking up the road so your legs stay fresher deep into a long run. Then you push, and the foam gives back. It rolls you forward with genuine bounce rather than the harsh snap of a plated racer. Hold half-marathon pace and it comes alive. It never feels dead or mushy, which is the usual trade with a plateless shoe this soft. What you do not get is the aggressive, forced turnover of a carbon racer like the Saucony Endorphin Speed 5: the Superblast asks you to drive the pace rather than doing it for you. For most training, and for a lot of runners on race day, that is exactly the ride you want.
Cushioning
Cushioning is the headline. With 45.8mm under the heel and 37.7mm up front, the Superblast 3 gives you maximum-stack protection that eats up long runs and back-to-back training days. The foam is soft but resilient, so it cushions the pounding without collapsing into a dead, flat feel by the end of a run. This is a shoe you can spend two hours in and step out of with your legs intact. The high stack does mean it sits a long way off the ground, so if you prefer a low, connected feel you will notice the height. For anyone chasing comfort and leg protection over distance, though, there is very little on the road that matches this much usable cushioning in a shoe still light enough to run fast.
