The Nike Free Focus Flyknit 2 Women's Training Shoe features an innovative sole that expands and contracts with every step—plus Flyknit construction for snug comfort and lightweight breathability.
Nike Flyknit technology was inspired by feedback from runners craving a shoe with the snug (and virtually unnoticed) fit of a sock. Nike embarked on a four-year mission with teams of programmers, engineers and designers to create the technology needed to make the knit upper with static properties for structure and durability. Then the precise placement of support, flexibility and breathability—all in one layer—was refined. The result is a featherweight, form-fitting and virtually seamless upper. This unprecedented precision maximises performance while reducing the material waste of traditional cut and sew by an average of 60%. The equivalent of six recycled plastic bottles are used in every pair of Flyknit shoes, saving millions of kilos of material from reaching landfills.
Nike Free OriginsAfter learning that Stanford athletes had been training barefoot on the university's golf course, three of Nike's most innovative and creative employees set out to develop a shoe that felt natural and weightless, similar to bare feet. The team spent eight years studying the biomechanics of runners' feet in motion. The results yielded a profound understanding of the foot's natural landing angle, pressure and toe position, allowing Nike designers to build an unconventional and flexible running shoe from the inside out.
