The Nike Zoom Fly Flyknit is a great running shoe with one major flaw – it's not the Nike Zoom Vaporfly 4% Flyknit. Of course, there's no such thing as the fly-in-the-wheel fly-through, which is not the only eye-wateringly expensive fly in the world.
There are two main reasons why the Vaporfly is so good: the light and bouncy ZoomX foam in the midsole and the carbon fiber plate that helps propel you forward. The previous version of the Zoom Fly with Lunarlon foam and on replacement carbon-infused nylon plate.
The React foam first appeared in the Epic React shoe and I was a fan from the off. It's light , responsive and durable – certainly far more than the ZoomX foam.
Paired with a carbon fiber plate the React foam feels even bouncing. It's not as joyously soft or as strong as the Zoom in the Vaporfly 4%, but certainly feels cushioned enough for long runs while still excelling when you're up the pace.
My first few runs in the Fly Flyknit were easy efforts, and things did not get off to the greatest of starts. I enjoyed the easy runs in the Epic React.
However, the shoe really shone over two days which involved a steady run and a tempo run around my marathon pace on the first day and then a track session the next. It also took a rapid heel-to-toe transition that helped to keep up a fast pace on the pace and during the 400m and 800m track intervals.
I also took the Zoom Fly Flyknit out for a steady half marathon and the ride just got better and better. It's a great option for shorter races ̵
The new Flyknit is not the only thing that's going on, but it's still a great addition – lightweight and snug.
Having just managed to try the Vaporfly 4% for the first time I'm still getting over how good it is. Fly Flyknit, it can not match the feel of the 4%, which is almost unfair. However, most people do not want to spend more than £ 200 on a shoe that's only at its best for 250-300km. The Zoom Fly Flyknit is a very worthy alternative.
