How does the VaporMax 2021 FK fit?

It runs narrow and snug. Many owners go up a half size, especially with wide feet.

Is it good for running?

It is a lifestyle shoe first. The air sole cushions well but is less stable than a dedicated running shoe.

What is the upper made of?

A Flyknit upper made partly with recycled materials, with a rubber outsole below.

How does it compare with the Air Max 2021?

The VaporMax uses a full-length air sole for a bouncier ride; the Air Max 2021 pairs air with foam for more stability.

Does it need breaking in?

Some owners find the air sole stiff for the first few wears before it softens.

How should I care for it?

Wipe the knit with a damp cloth and mild soap. Avoid machine washing, which can damage the air unit.

Our take on the NIKE MENS AIR VAPORMAX 2021 FK "White Royal Volt" DC9394 100

The Nike Air VaporMax 2021 FK is a lifestyle running sneaker built on a full-length VaporMax air unit that runs the whole length of the sole. The upper is Nike's Flyknit, made with recycled content, and the shoe sits on a rubber outsole with a waffle-inspired tread. It suits people who want a soft, bouncy ride and a bold, tech-heavy look for everyday wear. Against cushioned rivals like the Air Max 2021 or the Pegasus line, it trades a more conventional midsole for a trampoline-like air sole that some find unstable and stiff at first. Owners praise the cushioning and the look; critics point to the high, narrow fit and the price of the air unit's upkeep over time.
