Mizuno has taken the pursuit of lighter racing shoes to a figure that barely seems plausible: approximately 96g.
That is the stated weight of one Hyperwarp 96 in a 27cm size, rather than a claim that every size weighs exactly the same. Even with that qualification, it is the number that gives this forthcoming release its name and its appeal.
The Japanese brand plans to make just 696 pairs worldwide, with an initial release scheduled for December 4th. Announced in September, the shoe is a limited concept model built around the technology in Mizuno’s Hyperwarp racing range.
For anyone hoping to see it stacked beside the everyday trainers in their local running shop, expectations may need adjusting.
Even Lighter Than Adidas’ Lightest Racer
The comparison that puts 96g into perspective is the adidas Adizero Adios Pro Evo 3. Adidas launched that shoe as its first racing model below 100g, with an average published weight of 97g in a UK size 8.5.
Mizuno’s stated figure comes in a gram lower. On the manufacturers’ published numbers, it undercuts a rival whose exceptionally low weight is central to its appeal.
A single gram is hardly a reason to change your race plans. The point is the company Mizuno is keeping: even among shoes designed to strip away almost every unnecessary gram, the Hyperwarp 96 stands out.
These are manufacturer figures quoted for their respective reference sizes, rather than an independent comparison of equivalent samples. They establish the scale of Mizuno’s ambition, not proof that its shoe will make someone faster than the adidas.
What Has Mizuno Put Into 96g?
The Hyperwarp 96 combines a specially developed Enerzy XP+ Limited Edition midsole with a carbon Smooth Speed Plate and a lightweight Dual Skin Upper.
Mizuno’s US listing identifies PEBA foam, a TPU upper and a G3 outsole. Its Australian product page describes a precision carved midsole and an upper with material density varied around the foot.
The published sole heights are 39mm at the heel and 36mm at the forefoot, giving a 3mm drop. Despite the striking weight figure, there is still considerable cushioning beneath the runner.
The engineering question is how those elements work together once the shoe leaves the display stand. A very low weight attracts attention. The fit, grip and feel over race distance will determine how useful that weight saving actually is.
Built for the Sharp End
Mizuno’s US description places the Hyperwarp 96 firmly in the elite racing category, aimed at runners pursuing small competitive advantages.
For the average club runner, that makes it an interesting piece of footwear technology rather than an obvious addition to the shopping list.
A shoe designed around an extreme weight target also raises practical questions. How secure is the upper when cornering? How does the cushioning feel late in a race? What sort of use can an owner reasonably expect before performance begins to change?
Those questions cannot be answered by putting it on a kitchen scale.
Run Republic has not tested the Hyperwarp 96. This is a preview of the announced design, rather than a verdict on its performance or durability.
A Small Number of Pairs At a Substantial Price
Mizuno’s US website lists the Hyperwarp 96 at $600.
We could not verify an official Irish or UK retail price in the sources checked. Converting the American figure into euro or sterling would not establish what local buyers will actually pay.
Availability will also depend on the market. Mizuno’s Japanese announcement gives December 4th for initial sales through its own channels, followed by selected retailers from January 2027. Its US page also lists December 4th.
In Australia, Mizuno is using an online raffle to allocate pairs, with registration notifications planned for November. That arrangement should not be assumed to apply in Ireland or the UK.
With only 696 pairs planned worldwide, this is clearly a tightly limited release.
Why It Is Worth Watching
The interest in the Hyperwarp 96 extends beyond the small number of people who will buy it. It gives runners a concrete example of how far a manufacturer is prepared to push materials and construction in pursuit of lower weight.
What remains to be established is how that translates into the experience of racing, and what compromises buyers might encounter along the way.
