Who should buy
We believe that the Ortuseight Aeroflash is a spike that:
- Is ideal for those who prefer a softer, more cushioned ride than most sprint spikes offer.
- Delivers an impressively stiff and race-ready platform without the premium price tag.
- Is a great choice for athletes looking to try a high-performance spike from a less-known brand.
- Maximises underfoot cushioning by pushing stack height close to the World Athletics limit.

Who should NOT buy
Many sprint athletes prefer a firmer ride with minimal foam compression, whereas the Ortuseight Aeroflash is designed to deliver a noticeably softer underfoot feel. If that's your preference, we think the Nike Maxfly 2 is a better match.
We also believe that the Aeroflash's exceptionally stiff ride may feel too demanding for beginners. Instead, we recommend starting (and saving some money!) with the Nike Rival Sprint.

Cushioning
Heel stack
Ortuseight pushed the Aeroflash right to the edge of the current World Athletics regulations, which cap stack height at 20 mm for running spikes.

We measured 19.0 mm, leaving just 1.0 mm of headroom and maximising the amount of Cirrostratus foam allowed underfoot.

| Aeroflash | 19.0 mm |
| Average | 16.4 mm |
Forefoot stack
We also measured an 18.3 mm forefoot stack, another result that sits impressively close to the World Athletics limit. It's also worth noting that the Aeroflash has been officially approved by WA for competition, making it fully legal to race in.

| Aeroflash | 18.3 mm |
| Average | 15.5 mm |
Drop
Although Ortuseight advertises a 0 mm drop, our measurements revealed a tiny 0.7 mm offset instead. In our opinion, the difference is so small that even the most experienced track athlete would be unable to notice it.

| Aeroflash | 0.7 mm |
| Average | 0.9 mm |
Midsole softness
UpdatedThe Aeroflash features a Pebax-based foam, a material known for delivering good energy return. However, Ortuseight gave it a distinctive feel by opting for an unusually soft formulation, which measured just 26.6 AC on our Asker C durometer.
As a result, the ride feels more cushioned than what most sprint spikes deliver. In our opinion, runners looking for a firm, direct feel may find it too soft, whereas those who enjoy greater foam compression will likely appreciate its character.

| Aeroflash | 26.6 AC |
| Average | 43.2 AC |
Plate
The Aeroflash features a full-length plate positioned beneath the insole and directly above the Cirrostratus foam, allowing it to compress the midsole more effectively and maximise energy return. Ortuseight calls it the Kinetic Blade, and we have to admit it's a cool name.
Size and fit
Size
Internal length

| Aeroflash | 259.4 mm |
| Average | 261.0 mm |
Width / Fit
We created a gel replica of the shoe's interior, and we found that Ortuseight stayed remarkably close to the fit offered by most modern running spikes.
The widest part of the upper measured 87.7 mm, delivering the snug profile we'd expect from a sprint-focused design.

| Aeroflash | 87.7 mm |
| Average | 88.6 mm |
Toebox width
With 66.6 mm of toebox width, the Aeroflash provides a secure, locked-in fit that's ideal for explosive efforts, relays, and sprint racing, where minimising foot movement inside the shoe is a top priority.

| Aeroflash | 66.6 mm |
| Average | 68.8 mm |
Toebox height
The toebox height brought no surprises either. At 25.9 mm, it landed remarkably close to our lab average for running spikes.
As a result, the fit feels comfortably secure without creating excessive pressure over the toes.

| Aeroflash | 25.9 mm |
| Average | 25.9 mm |
Flexibility / Stiffness
The Aeroflash comes with remarkable stiffness. It required 29.2N to reach a 30-degree bend in our flexibility test, confirming that the Kinetic Blade plate is far more than a gimmick.
In our opinion, this spike rewards athletes capable of generating the powerful stride needed to fully unlock its performance.

| Aeroflash | 29.2N |
| Average | 14.8N |
Weight
At just 5.9 oz (167g), the Ortuseight Aeroflash delivers a reasonable weight for a sprint spike that pushes stack height nearly to the World Athletics limit. Even more remarkably, it comes in lighter than the Nike Maxfly 2!

| Aeroflash | 5.9 oz (167g) |
| Average | 5.6 oz (160g) |
Stability
Torsional rigidity
UpdatedThe Kinetic Blade also increases torsional rigidity, although not to the same extent as it boosts longitudinal stiffness. We measured 10.5 Nm in this test, placing the Aeroflash right around the average for running spikes.

| Aeroflash | 10.5 Nm |
| Average | 10.6 Nm |
Heel counter stiffness
The heel counter folds with very little resistance, and during our test runs we never found it getting in the way. In our opinion, that's exactly the kind of design we'd expect from a spike built for sprint training and racing. It's a clear 1/5.
| Aeroflash | 1 |
| Average | 1.6 |
Midsole width - forefoot
We measured the Ortuseight Aeroflash at 93.5 mm wide in the forefoot, providing a solid platform for explosive toe-offs and powerful landings.
And that's an especially valuable trait for hurdlers, where stability at touchdown is critical.

| Aeroflash | 93.5 mm |
| Average | 95.9 mm |
Midsole width - heel
The heel is also slightly wider than what we typically see in running spikes, and we believe that was a deliberate choice. Given the Aeroflash's softer midsole foam, the broader platform helps add a welcome measure of stability.

| Aeroflash | 69.5 mm |
| Average | 63.7 mm |
Durability
Toebox durability
Given the highly-breathable mesh used by Ortuseight with countless ventilation holes, we fully expected the upper to struggle in this durability test. It did exactly that, earning the lowest possible score of 1/5.
| Aeroflash | 1 |
| Average | 2.2 |
Heel padding durability
The heel padding performed much better with a 4/5 score, which was more or less what we expected. With barely any plush foam to tear through, the Dremel left behind only minor damage by the end of the test.
| Aeroflash | 4 |
| Average | 3.9 |
Outsole thickness
We measured the outsole at 2.9 mm thick, a result that's right in line with what we typically see in racing spikes.

| Aeroflash | 2.9 mm |
| Average | 2.7 mm |
Misc
Insole thickness
We found the insole to be very thin at just 1.9 mm, a likely choice by Ortuseight to maximise the amount of midsole foam while remaining within World Athletics' stack height regulations.

| Aeroflash | 1.9 mm |
| Average | 2.6 mm |
Tongue padding
The Aeroflash delivers exceptional lockdown through its lacing system while keeping pressure evenly distributed across the instep. As a welcome bonus, Ortuseight also includes laces with a subtle sawtooth texture that helps them stay securely tied.

We also measured the tongue at just 1.1 mm thick, exactly what we'd expect from a performance-focused sprint spike. And to complete the design, Ortuseight added dozens of perforations throughout the tongue, a thoughtful touch that improves airflow on hot days at the track.

| Aeroflash | 1.1 mm |
| Average | 2.2 mm |
Heel tab
The heel of the Ortuseight Aeroflash might look familiar, and for good reason. It closely resembles the iconic design used in the Nike Dragonfly 2, featuring a circular cutout that enhances heel lockdown while helping relieve some pressure.

| Aeroflash | None |
Price
The Ortuseight Aeroflash is competitively priced considering the top-tier technologies it packs in. In our opinion, the biggest challenge isn't its value but its limited availability, as this brand can be difficult to find in some regions.
| Aeroflash | $120 |
Removable pins
We also liked that all six pins are removable, with Ortuseight including a spike wrench in the box. Feel free to swap in your lucky set before race day.
