Nike this week launched a new running shoe for the 2012 Olympics that weighs a mere 160g (5.6 ounces) for a size 9.
That's very light and in fact 19% lighter than the "Nike Zoom Streak 3, a shoe worn by first, second and third place athletes in the men’s marathon at the 2011 World Championships," according to Nike.
The new shoe technology called Nike Flyknit, uses "yarns and fabric variations are precisely engineered only where they are needed for a featherweight, formfitting and virtually seamless upper," says Nike
“Today we’ve unveiled technology we believe has the potential to change sports performance,” said Nike President and CEO Mark Parker. “Nike has always been committed to bringing the best innovations to athletes at every level and we’ve done that today in a powerful way. The Nike Flyknit upper redefines the idea of running footwear: Lightweight and virtually seamless, it acts like a second skin for the foot and is precision engineered in one piece and one layer to minimize waste, dramatically changing how footwear is designed and manufactured.”
