Nike Flyknit Technology sound crazy enough? As if Nike shoes weren’t lightweight and high-performing already, Flyknit Technology – a result of four years of research – has pushed the boundaries of ‘lightweight’ by creating a pliable upper material that allows the shoe to weigh a paltry 5.6 ounces by adopting the fully knitted-in and seamless upper. The Flyknit Racer is also 19% lighter than the Nike Zoom Streak 3, a top-tier marathon shoe worn by the first, second, and third-place finishers at the 2011 World Championships. As part of the July release debut of the Flyknit Collection, the three-headed monster briefly dubbed HTM (Hiroshi Fujiwara, Tinker Hatfield, Mark Parker) has designed a special capsule of the Nike HTM Flyknit Collection – one Flyknit Racer, colored in a U.S.A. colors that actually debuted that U.S. Track & Field trials this past January, and two Flyknit Trainers, which features a full-length LunarLon outsole for all-day comfort. Check out the entire Nike HTM Flyknit Collection after the jump and let us know what you think of Nike’s latest technology. A very limited run of the Nike HTM Flyknit Collection will release tomorrow at 21 Mercer.
