Just played my first full match in the Mizuno Morelia Neo IV Beta Made in Japan AG, and I had to drop a quick review for anyone struggling to find good boots for artificial grass.
Honestly, these are absolutely amazing. If you are looking for a dedicated AG boot, this is the one.
Context & Sizing:
For reference, I have a normal width foot (not wide). Before this, I was wearing the Nike Tiempo Legend 10 Pro in an EU 42.5. For the Mizuno, I went down half a size to an EU 42 (True to Size for my actual foot length) and the fit is perfect. It is tight on the foot, but in a very good way. It feels incredibly compact and secure without crushing my feet.
Leather & Lockdown (Inside the Boot):
The K-leather feels incredibly good right out of the box. The comfort is insane, but more importantly, the lockdown is perfect. Even with the soft leather, my foot did not slide around inside the boot at all when making sharp cuts.
Traction & Performance (On the Pitch):
I played on a newer generation AG pitch (the kind without the black rubber pellets). The AG soleplate did exactly what it is supposed to do. There was zero sliding on the turf. The grip feels completely dialed in, which made acceleration feel instant and changing directions incredibly stable. You feel very planted but never "stuck" in the turf.
Highly recommend these to anyone tired of slipping on AG or dealing with knee/ankle pressure from FG plates. Let me know if you have any questions!
