Nike Men's Free 4.0 Flyknit Running Shoes

The revolutionary Nike Flyknit upper will give you the feeling of pulling on a sock that stabilizes your foot across Nike's midsole. The upper only consists of polyester, which provides unique breathability, flexibility, and support.

With a 6 mm. difference in height from heel to forefoot, is Nike Free Flyknit 4.0 is the most flexible and shock absorbing shoe in the collection. The little difference from the heel to the forefoot brings you closer to the ground, creating a more natural feeling during your run.

The shoe is built around the familiar and ultra-lightweight Flywire threads encircling the middle foot, which can be adjusted through the laces. This means the shoe offers greater support and a more dynamic fit, which automatically follows your foot movements.

The Nike Free Concept originates in Stanford, where Nike looked into the training methods of the very successful athletes there and found out they trained barefoot. 3 of Nike's most esteemed and creative innovators went to work on this basis and in 2002 they began work on the first Nike Free by mapping the foot's biomechanics.

8 years later the first Nike Free went on sale and the result was a shoe that "understood" your feet, how they land, where the pressure is applied. It was an unconventional shoe but sparked the interest of many around the world.

The Nike Flyknit technology is based on the wishes of the world's very best marathon runners, who wanted an ultra-light and barefoot fit.
