Breathable. Supportive. Nike Flyknit technology uses high-strength fibers to create lightweight uppers with targeted areas of support, stretch and breathability.

Nike Free Flyknit The Flyknit upper provides a sock-like fit, while the Nike Free midsole expands for more dynamic movement. Each pair is designed with more cushioning than the Free RN Motion to help keep your feet comfortable and supported during every mile of your run.

Slideshow: sports brand Nike have created a range of running shoes with knitted uppers made in one piece. The Flyknit shoes have a light, almost seamless upper, knitted with different structures for different areas in polyester yarn with varying elasticity, thickness and strength.

2012 Nike introduced its Flyknit technology in 2012 and little did they know it would define an era of sneakers. Their goal was to create a material that is high-performing, comfortable, and eco-friendly. Their new technology, which debuted with the Flyknit Racer, would go on to achieve much more than its original goals.

With Flyknit, Nike created a seamless upper that could be built to size – reducing waste by around 60% – while also allowing the upper to be micro-engineered to suit the needs of different silhouettes. Essentially, Nike began knitting in the necessary structure and support.

I knocked the FlyKnit Shields down a point because they aren't fully waterproof, but otherwise they're stellar. You don't want to take them on the trail, but they're perfect for the street.

First launched in 2006, the Nike Free was the first running shoe that was meant to be used as a training tool, to be added to your rotation of running shoes.

Nike Free always helps enhance your body's natural motion, but the barefoot-like-running experiences vary from shoe to shoe. These variances are graded on the Free Scale. The lower the number, the more barefoot-like the shoe.

It provides adequate cushioning for the marathon distance for any runner with a specific time goal in mind, and makes a great trainer for those mechanically gifted enough to run in less shoe most of the time.

Introduced in 2012, Flyknit was developed by Nike to create a high performance material unlike anything before and reduce waste at the same time.

Nike Flyknit is a lightweight fabric precision-engineered with an average of 60% less waste than in traditional footwear upper manufacturing.

What is Nike Flyknit? A material made up of strong yet lightweight strands of yarn that have been woven into a one-piece upper, securing an athlete's foot to the shoe platform.
