A6 Sonic Blast vs the Best Plated Trainers: Endorphin Speed 5, Hyperion Max 3 and Zoomfly 6

Introduction

The A6 Sonic Blast has landed as a plated, above-max-stack trainer, and a lot of runners are asking the obvious question: how does it stack up against the established names in the plated daily trainer category? For this comparison, we put it up against three of the most popular alternatives right now: the Nike Zoomfly 6, the Brooks Hyperion Max 3, and the Saucony Endorphin Speed 5.

All four shoes were measured in a UK 11 / US 12 to keep the numbers comparable, and each pair was run over a mix of easy miles, tempo work and longer efforts. If you are shopping for one plated trainer to do it all, this breakdown should help you land on the right pick.

Evaluation Criteria

Each shoe was compared across stack height, weight, ride feel, plate stiffness, upper comfort, grip and versatility. The measurements come from the actual pairs tested: the Hyperion Max 3 is easily the heaviest of the bunch, with the Endorphin Speed 5 coming in as the lightest. The Sonic Blast and the Hyperion Max 3 both carry above-max stacks at 48 mm in the heel in this size.

On pricing, the Endorphin Speed 5 is the most expensive of the four, while the Zoomfly 6 is actually the cheapest this time around. Those practical differences matter as much as ride feel, so keep them in mind as you read through.

A6 Sonic Blast vs Saucony Endorphin Speed 5

The increased stack in the Sonic Blast over the Endorphin Speed 5 is quite noticeable on foot, but there is a little more squash to proceedings in the Saucony, particularly in the rear of the foot. If you like your shoes to feel compressive and soft, the Endorphin Speed 5 is the better bet. Both models have a similar drop, so that is not much of a differentiator here.

The nylon plate in the Speed 5 feels a little more flexible and less rigid than the one in the Sonic Blast, and you also get a good ounce less weight, which makes it a slightly more nimble, more exciting shoe to run in. The Sonic Blast’s foam does soften up a little over time, but it never gets close to the out-of-the-box softness of the Speed 5. For a lighter-framed runner, the Power Run PB material is simply more energizing and responsive, letting you run your own way, whereas the Sonic Blast feels a little more controlling. The Flight Foam Turbo Squared in the Sonic Blast is also clearly a different formula from the one in the Mega Blast; after plenty of miles in both, they feel completely different.

The Speed 5 can easily serve as a daily driver. It does almost everything well: easy miles, recovery miles and fast clips, and it was pleasant at tempo pace too. Many runners still race in it, and it tends to cost a little less. If you want one shoe that does it all, the Endorphin Speed 5 is a good bet. The Sonic Blast is firmer across the board and might suit heavier-built runners better, but if we had to pick a single pair between the two, the Endorphin Speed 5 wins.

A6 Sonic Blast vs Brooks Hyperion Max 3

The Hyperion Max 3 makes the Sonic Blast seem light by comparison. It weighs about an ounce more than the A6 shoe, and you genuinely feel it on foot. It is quite a chunky beast. The stack heights are pretty much identical, and both deliver a firmer, more rigid, controlling ride with prominent rocker geometry that encourages rolling through the heel into the forefoot. If that rolling style does not suit you, neither shoe will suddenly change your mind.

Where the Brooks pulls ahead is grip: there is more substantial, deeper rubber on the outsole, and that is likely where some of the extra weight comes from. There is also a lot of padding in the tongue and around the ankle, which makes the Sonic Blast’s upper seem almost minimal by comparison. From an upper perspective, the Sonic Blast is the more refined of the two, with easy lockdown, better breathability and a lighter feel. The balance is better balanced as well; the Hyperion Max 3 feels a bit bottom-heavy, with a lot of mass sitting in the lower section of the shoe.

Neither shoe is super soft or extremely forgiving underfoot, and both are set up to use that extra heel stack. If you are a fan of the older Zoomfly Flyknit, the Sonic Blast could well appeal to you. Between the two, the Sonic Blast is the pick simply because it is more versatile, though the Hyperion Max 3 may reward a few more outings before a final verdict.

A6 Sonic Blast vs Nike Zoomfly 6

The Zoomfly 6 is cheaper than every other shoe in this comparison, and it is the only one here with a carbon plate, where the others use nylon or PB-based stiffening elements. That plate gives a little more snap: it feels more responsive at toe-off, and the ZoomX foam with ReactX underneath is impressively durable with good longevity.

The foam combo in the Zoomfly 6 is not as soft and compressive as the Endorphin Speed 5, but it is certainly a lot more responsive than the Sonic Blast, and it is a much lighter package too, with a good 20 g in the Nike’s favour. Yes, the Zoomfly 6 is not as stacked as the Sonic Blast, but unless you are doing extreme long runs, there is easily enough cushion here for training. It also feels good across a wide range of paces, whereas the Sonic Blast seems to fit a very specific niche, that kind of cruising-speed zone. And realistically, if you are heading out for a longer, slower effort, you will probably reach for a plateless shoe anyway.

Grip is another clear win for the Nike. The waffle lugs feel more versatile across different terrains and surfaces. The exposed midsole on both shoes has held up well, though thorns occasionally work into the Sonic Blast’s foam, something that has not really happened with the Zoomfly 6. On the other side, the Sonic Blast offers a slightly more stable ride with a bit more surface area, which could suit runners with wider feet or anyone wanting a more consistent feel across the foot. Still, the Zoomfly 6 is a genuine workhorse and arguably the best iteration of the line in years. If we had to choose one pair, it would be the Zoomfly 6, simply because a slightly more grounded, softer and more fun shoe is hard to beat.

Overall Buying Advice

The Sonic Blast is arguably the best of the above-40 mm cushioned plated shoes tested here, and it earns real praise for stability, upper refinement and lockdown. But it is a rigid, firm shoe that thrives at cruising speeds, so it rewards runners who specifically want that controlling, max-stack feel.

For everyone else, the alternatives cover more ground. The Endorphin Speed 5 is the do-everything daily driver, the Zoomfly 6 is the responsive, durable all-rounder at the friendliest price, and the Hyperion Max 3 suits runners who love big stack with aggressive rocker geometry and deep outsole rubber. Match the shoe to the rides you actually do most, and you will not go far wrong.

Conclusion

The A6 Sonic Blast is a serious entry in the above-max-stack plated trainer space, with a well-built upper and a notably stable ride. But in direct comparisons, the Endorphin Speed 5’s softer, nimbler ride, the Zoomfly 6’s responsiveness, price and durability, and even the Hyperion Max 3’s deeper grip each give the incumbents a genuine edge. If the firm, controlling max-stack feel is what you want, the Sonic Blast delivers. If you want one shoe that does everything well, the competition still holds the crown for now.
