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.

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.

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 is a minimalist running shoe. It was introduced in 2005 after Nike representatives observed Nike sponsored track athletes training barefoot.

It's ultimately a matter of preference, but Kim says many elite athletes will use the Nike Free as a shoe for warmups and cool-downs, as well as gym strength-training workouts.

In addition to short runs and drills, the Free RN 5.0 would make a good choice for a workout shoe, or one to wear for walking, to aid strengthening the muscles in your feet.

With key features like breathable mesh uppers, extra cushioning through the heel, and arch support, Nike sneakers are designed to provide the kind of comfort and stability that you need on long walks.

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.
