Description

Streakfly 2 HF6416-401 is tuned for runners who want pure speed on race day.
It targets fast road efforts, especially from the mile up to 10K.
Because the build stays minimal and light, it feels quick on your feet when you push the pace.

First, Nike integrates a full-length carbon-fiber Flyplate to create a propulsive feel.
This plate helps you transition smoothly through each stride.
As a result, toe-offs feel snappier, and you can carry speed more easily.
Moreover, the plate supports confident cornering, which matters when you race on turns or tight sections of the course.

Next, the midsole uses ZoomX foam, Nike’s most responsive foam.
ZoomX delivers high energy return, so the shoe feels lively without needing extra weight.
In addition, the cushioning runs heel to toe, which helps keep your ride consistent from the first kilometer to the last.
Therefore, you can stay fresh longer while still feeling fast.

The upper focuses on lightweight support.
It uses Flyknit material to keep the feel breathable and streamlined.
So you get ventilation and a close, race-ready fit without bulky layers.

Underfoot, the outsole uses a thin, sticky, webbed traction material designed to reduce weight while still providing grip.
Because the outsole stays minimal, the shoe maintains its “disappears on foot” sensation.
At the same time, it helps you stay steady on typical road surfaces during fast sessions.

If your goal is to outpace competitors and chase a new personal best, Streakfly 2 HF6416-401 delivers lightweight speed, responsive cushioning, and carbon-driven efficiency in one clean racing package.
