The team over at FastPass has deconstructed the Nike Kyrie 4, and the findings are conclusive.
Nightwing2303’s glowing Nike Kyrie 4 Performance Review made note of improved fit, great traction, and much improved cushioning. Now that the Kyrie 4 has been deconstructed, we can see where that added cushioning comes from.
First off, the Zoom unit in the heel has gotten longer, wider, and thicker. You can see a comparison of the Kyrie 3 and Kyrie 4 at the bottom of this piece, but the Zoom Air unit in the Kyrie 4 is now 11.36mm thick (versus the Kyrie 3’s 10.56mm) — that’s nearly a millimeter thicker.
Moreover, the heel Zoom Air unit is now nearly 4.5mm longer, and over 1.5mm wider. The Kyrie 4 also uses an OrthoLite insole that is nearly 1mm thicker than what was used in the Kyrie 3, and that rides atop a Cushlon midsole that is just slightly less dense than the midsoles of the Kyrie 2 and 3.
While many of these changes are numerically small, the difference in feel on-foot has been dramatic.

Probably my favorite Nike/Jordan since the Melo m9. The upgrades were needed, and it’s great to see the Kyries got all the updates, the ‘no shortcuts’ mentality should be more common in sneakers.
So the entire midsole is Cushlon? I originally thought it was just the forefoot.
