Our verdict

85
Great!

The Nike Mercurial Superfly 8 Elite KM FG is NOT a bad shoe at all, we just have to be clear on that. It just follows a considerably well-reviewed Superfly 7, and not all attempts at improvement translates to better performance. Still, it's a good shoe, and buying it isn't a bad move.

Pros

  • Reliably grippy
  • Nice texture for ball control
  • Fits nicely
  • Light
  • Stylish
  • Stable and supportive

Cons

  • Needs break-in
  • Really expensive
  • Gimmicky

Who should buy the Nike Mercurial Superfly 8 Elite KM FG

The 8th Superfly is still great for players who love a well-rounded cleat for their well-rounded games. This soccer cleat delivered on aspects that matter such as traction, ball control, and weight.

Of course, Kylian Mbappe will go crazy over this special version of the Superfly 8.

Who should NOT buy the cleat from Nike

The Nike Mercurial Superfly 8 Elite KM FG won't be for the following buyers:

  • wide-footers
  • athletes on a budget
  • feet prone to blisters

For these players, sticking with the Superfly 7 is an option. The more budget-conscious among them can also go for the Pro version or lower of the Superfly 8.

Nike Mercurial Superfly 7 vs. Nike Mercurial Superfly 8

Compared to the Superfly 7, the Superfly 8 is

  • less pliable, so players are prone to blisters.
  • has a thinner upper, so it does not provide as much protection as the Flyknit used in the 7

When it comes to traction, the Superfly 8 KM FG means business!

The sole plate and stud configuration work together that gives a "very solid (traction) package." No complaints there.

The matte feel is the real deal!

The engineered mesh on the forefoot had a "matte feel," which effectively enhanced ball control.

The fit is great!

Soccer players report that these cleats hugged their feet just right.

Wide-footers still have to make size adjustments, though.

The cleat is light and supportive despite having a few extra features.

Though this is a tiny bit heavier than the previous version, the Superfly 8 Elite feels so light. The upper also felt like it was more aligned with the foot's movement, resulting in a good lockdown.

This soccer cleat, however, has features that do not really have functional significance; they are there for show. A good example is the rear Speed Wings. 

Performs well, looks good

We just couldn't help it; these mid-top cleats from Nike really looked great.

However, we are bummed that the Nike Mercurial Superfly 8 Elite KM FG is just a collared and ridiculously more expensive version of the Mercurial Vapor 14.
