Debuted in 2004, the Nike Free 5.0 introduced the concept of natural motion to Nike Footwear design. To celebrate 10 years of Nike Free, Nike Sportswear uses the technology of today to improve classics and introduces the Nike Free Breathe. Constructed with a performance approach to lifestyle design, the Nike Free Breathe builds on the natural motion ethos by honoring the classic aesthetic of the original and allowing the foot to feel freer than ever with supreme breathability.
Inspired by runners training barefoot on grass, the Free Breathe expands on the barefoot concept by improving breathability. The deconstructed, double-sided mesh upper allows air to rush through the shoe for a barefoot-like sensation. With its unstructured breathable upper, the Nike Free Breathe is suited for sockless wear in the midst of sweltering summers. The Free Breathe is also updated with the same traditional tongue and Nike Sportswear-specific outsole that is also found on the Free OG. In 2004, the Nike Free 5.0 changed how footwear moved and in 2014, the Nike Free Breathe will change how footwear feels.
