Only just announced in late February, we got an exclusive first look at the Nike Flyknit running shoes this week.
We weren't able to take the samples for a run around the park because they're being closely guarded by Nike until they're released to the public this summer, but we were all blown away by how light they are.
Nike sent us two models, the Flyknit Racer, which is a high performance marathon shoe, and the Flyknit Trainer+, which is an everyday running shoe.
The proprietary knit upper, which Nike has been engineering for the last four years, was designed to be "one of the lightest, best fitting running shoes Nike has ever made."
Using yarn and fabric variations, the formfitting Flyknit racer weights just 5.6 ounces, and is virtually seamless. That's about 20% lighter than the Nike Zoom Streak 3, which was worn but the 1st, 2nd and 3rd place finishers of the marathon at the 2011 World Championships.
The Flyknit is Nike's answer to the recent trend towards lightweight minimalist shoes, after receiving feedback from runners who craved a shoe that fit like a sock with a snug fit that goes almost unnoticed.
The Flyknit Racer and Trainer+ will be available in July, 2012 and the price point will be around $150.
