Who should buy
Having tested the limits and capacities of the Nike Cosmic Unity 3, we consider it an excellent option for the following:
- small forwards who need tonnes of support and stability
- athletes who mostly play on outdoor courts
- savvy buyers who are willing to pay more for premium durability
Who should NOT buy
Having tested the previous version of the Cosmic Unity, we believe that the v3 is a bit of a letdown when it comes to cushioning and weight. If you want a softer and more responsive Zoom Air cushioning, go with the v2. We also found that it is a whopping 2.3 oz (65g) lighter!
Another great alternative, in our opinion, is the Nike KD 15. It is 1.7 oz (48g) lighter, has plusher and bouncier cushioning, and is just as great for outdoor courts.
Breathability
When we first saw all those layers of mesh and knit embracing the upper of the Cosmic Unity 3, we instantly thought "Uh-oh, here comes a toaster." And yet, our smoke machine test proved that this Nike shoe found a way to ventilate the interiors.
Based on the amount of smoke passing through the upper, we assessed its breathability with a rating of 3 out of 5.
It is clear from the transparency test below which parts of the upper are responsible for the airflow.

Durability
Toebox durability
The wear resistance of this Nike shoe is INSANE!
In addition to its mesmerising looks, the embroidered upper of the Cosmic Unity 3 is also impressively strong. It survived our 12-second Dremel test with very minor damage and deserved the highest rating of 5/5. No wonder it is advertised for outdoor use!
Seeing what the same test did to the cheaper Nike Lebron Witness 7 (£120), it becomes clear why the Cosmic Unity 3 is asking for £170.
Of course, we couldn't help but explore the shoe's upper under our microscope in an attempt to reveal its secret durability formula.
We can see how multiple layers of woven fabric create several layers of defence on the Nike Cosmic Unity 3. This shoe is ready for some serious wear and tear.
Cosmic Unity 3 | 5 |
Average | 3.7 |
Heel padding durability
Back in the heel, the collar padding also showed excellent results in our Dremel test. Pressing the tool against the material for 4 seconds, we saw smaller damage compared to basketball shoes on average.
In this part of the upper, we rated the Cosmic Unity as 3 out of 5.
Cosmic Unity 3 | 3 |
Average | 3.5 |
Outsole hardness
The shoe's unmatched durability includes the outsole as well.
Measuring the hardness of its rubber with a durometer, we found it to be 86.5 HC. This is harder than 81% of our lab-tested basketball shoes. And in our experience, it takes much longer to wear through hard rubbers.
This fact in combination with our playtests allows us to wholeheartedly recommend the Nike Cosmic Unity 3 for outdoor use.
Cosmic Unity 3 | 86.5 HC |
Average | 81.9 HC |
Outsole thickness
We also use a calliper to check how thick the outsole is. At 3.5 mm, it is not among the thickest we've seen.
But we wouldn't be so concerned about that because the nature of the treads on the Cosmic Unity 3 looks very reassuring. Wide and deep, these lugs are not easy to wear off.
Based on all of our findings in the durability department, we can claim this Nike shoe to be one of the best for outdoor use.
Cosmic Unity 3 | 3.5 mm |
Average | 4.0 mm |
Weight
Apparently, being a durable shoe has its price.
The Nike Cosmic Unity 3 gained some serious weight compared to its predecessor. It now tips the scales at 15.7 oz (444g) whereas the average of our lab-tested hoop shoes is 13.7 oz (387g).
It feels very substantial underfoot but it seems to be the trade-off for the unmatched wear resistance and overall support.
Cosmic Unity 3 | 15.66 oz (444g) |
Average | 13.79 oz (391g) |
Cushioning
Heel stack
The shoe's cushioning comprises a drop-in midsole that sits on top of an embedded midsole. We measured the combined stack height of these two.
In the heel, our calliper shows 27.9 mm of stack, which is slightly thinner than average but still in the medium range.
Less cushioning typically translates to a better ground feel and we can confirm that the Cosmic Unity 3 feels more grounded.
Cosmic Unity 3 | 27.9 mm |
Average | 29.2 mm |
Forefoot stack
In the forefoot, we measured the stack height at 20.7 mm. It is also considered average for a basketball shoe. It is neither too thin to hurt the ball of the foot not extra cushioned.
Cosmic Unity 3 | 20.7 mm |
Average | 21.7 mm |
Drop
Calculating the difference between the heel and the forefoot height, we get a drop of 7.2 mm.
This slight elevation of the heel above the toes is right at the average of hoop shoes. We believe that it will suit most players.
Bigger guys and gals, on the other hand, may benefit from a higher drop as it gives more impact protection in the heel. Some shoes like that include the Adidas Dame 8 (10.4 mm).
Cosmic Unity 3 | 7.2 mm |
Average | 7.5 mm |
Midsole softness
To us, this part of the shoe has become the biggest disappointment.
The cushioning of the Nike Cosmic Unity 3 is a far-far cry from the brand's claim of "cloud-like cushioning." We repeated the durometer measurement several times to make sure we are not biased and yet every time the tool confirmed our experience - this shoe is firm. At 33.3 HA, the Cosmic Unity 3 is about 20% firmer than average.
Because of that, the shoe feels dense (and even thin) and definitely lacks impact protection for our moderate body weight. Unfortunately, it is a downgrade from the second iteration which was 32% softer and felt amply cushioned despite the lower stack height.
Cosmic Unity 3 | 33.3 HA |
Average | 24.7 HA |
Insole thickness
Because the shoe comes with a drop-in midsole, there is no insole in the Cosmic Unity 3 per se.
However, if you are wondering, the heel thickness of this component is 14.5 mm.
We are not exactly sure why Nike went with this midsole design. But at least it gives us an opportunity to replace its underwhelming cushioning with something more fun and protective. Not to mention that it gives way to using custom orthotics.
Cosmic Unity 3 | 0.0 mm |
Average | 4.8 mm |
Stability
Lateral stability test
Luckily, the Cosmic Unity 3 comes back strong when it comes to support and stability. This shoe made us feel contained like no other!
The first salute goes out to supportive materials on the upper. All those sturdy woven layers of Flymesh and Flyknit blend together to lock the foot in place. We experienced zero in-shoe movement.
Just look how little stretch (if any) there is in the upper!
Torsional rigidity
Our next shoutout goes to the plastic shank embedded into the midsole. It extends up on both sides, firmly bracing the arch. We haven't seen expanded shanks like that in quite some time.
This design is responsible for the shoe's increased torsional rigidity. Twisting it is not that easy! On a scale from 1 to 5, where 5 is the stiffest, we rated it as 4.
We consider it an essential stability component of the Nike Cosmic Unity 3.
Cosmic Unity 3 | 4 |
Average | 4.4 |
Heel counter stiffness
The shoe's heel cup was another pleasant surprise. First of all, it is notably stiffer than most basketball shoes. Giving it a good squeeze, we rated its stiffness as 4 out of 5.
Secondly, the shoe's rear foot is designed in such a way that our heels ended up sitting quite deeply in it. Heel slippage is simply non-existent here.
Cosmic Unity 3 | 4 |
Average | 3.7 |
Midsole width - forefoot
Finally, we cannot leave the shoe's wide base without attention.
Measuring the widest part of the forefoot with a calliper, we found it to be 115.3 mm. This is a little wider than average.
Having a wide landing area, we felt extra confident making sharp direction changes.
Cosmic Unity 3 | 115.3 mm |
Average | 115.0 mm |
Midsole width - heel
The Cosmic Unity 3 also features a wide heel area. We measured its widest part at 91 mm. A solid average for a hoop shoe.
Cosmic Unity 3 | 91.0 mm |
Average | 90.3 mm |
Flexibility
Stiffness
Being such a sturdy shoe, the Nike Cosmic Unity 3 loses a bit on the flexibility front.
It doesn't bend very easily on the foot and as our lab test shows, it's not very bendy per se. It took 44N of force to get the shoe to a 90-degree angle, according to our gauge reading. This makes the shoe 5% stiffer than the average. Not critical but noticeable.
We anticipate that the shoe will get more flexible with use but the break-in period is going to take a while.
We felt less manoeuvrable in the Cosmic Unity 3 but in return, we got smoother heel-to-toe transitions and enhanced stability.
Cosmic Unity 3 | 44.0N |
Average | 38.5N |
Grip / Traction
The grip is fabulous on the Nike Cosmic Unity 3. We mostly tested the shoe on a rubberized outdoor court and felt very surefooted. But we can readily recommend it for hardwood and concrete surfaces too.
We had to wipe the dust off much less frequently compared to other basketball shoes.
Size and fit
Toebox width - widest part
We measured the widest part of the shoe's toebox at 105.4 mm. This is a few millimetres wider than average and is a pretty good sign for wide footers.
Cosmic Unity 3 | 105.4 mm |
Average | 101.6 mm |
Toebox width - big toe
Towards the toes, the toebox goes from being above-average width to simply average. We measured the width at the big toe at 76.7 mm.
In our opinion, the Nike Cosmic Unity 3 will accommodate most foot shapes perfectly. Except perhaps the really wide feet. We recommend these players to go a half size or even a full size up because the Cosmic Unity 3 is not available in wide.
Cosmic Unity 3 | 76.7 mm |
Average | 76.9 mm |
Tongue: gusset type
Surprisingly for its higher-end price point, the Cosmic Unity 3 doesn't have a gusseted tongue.
However, this was never an issue for us as the tongue stayed in place and wrapped around our insteps comfortably.
The tongue is pretty wide and is made of a neoprene-ish material, which apparently makes up a success formula for this Nike shoe.
Cosmic Unity 3 | None |
Comfort
Tongue padding
The shoe's tongue is much thinner than average. At 4.9 mm, it is nearly twice thinner. And yet, it feels fairly well-padded.
We think that more padding in the tongue would be unnecessary as the shoe's upper offers plenty of support and in-shoe comfort as is.
Cosmic Unity 3 | 4.9 mm |
Average | 9.4 mm |
Heel tab
Because the edge of the shoe's collar is made of a pliable Flyknit material, having a finger loop to assist with putting it on is pretty handy.
Cosmic Unity 3 | Finger loop |
Removable insole
Remember that taking the insole out of the Nike Cosmic Unity 3 equates to removing the shoe's cushioning entirely. So you would need to find a thick replacement of at least 12 mm in the heel.
Cosmic Unity 3 | Yes |
Misc
Sustainable materials
As a final bonus, the Cosmic Unity 3 is claimed to be partially made of responsibly sourced materials. These include recycled post-manufactured and post-consumer waste like yarns, textiles, and plastics.
