Is it possible to improve on a shoe that already is meant to decrease your marathon time by four percent? Nike says it is possible. The company is releasing two new updated version of shoes that are already designed to improve on marathon times. The shoes are the Nike Zoom Vaporfly 4% and the Nike Zoom Fly Flyknit.

Nike Zoom Vaporfly 4% Flyknit

The Nike Zoom Vaporfly 4% was first released last year. The shoe features the same Nike ZoomX foam and full-length curved carbon fiber plate. Together, these two technologies created a four percent improvement on marathon times when compared to Nike’s current fastest racing shoe.

The updated version of the Vaporfly 4% has a Flyknit upper for a more breathable and flexible upper. The midsole and outsole technologies remain the same, the company just improved on the upper.

The shoe releases October 4 in North America, October 1 throughout all of Europe, September 6 in China, and September 6 in Japan.

Nike Zoom Fly Flyknit

The Nike Zoom Fly was released last year as well. If you didn’t get a chance to get your hands on the Vaporfly 4%, the Zoom Fly was the next best option.

The updates to the Nike Zoom Fly Flyknit include Lunarlon with React foam and a full-carbon fiber plate. In addition, the shoe receives the flyknit upper just like the Vaporfly 4%.

We are currently testing these shoes so stay tuned for a full review!

The Zoom Fly Flyknit has already been released in North America, Europe, and China. It releases on October 4 in Japan.
