The Nike Free came out I think my sophomore year in high school. I got a chance to try it out at a Sparq facility and to me it was errything. Actually had a pair all the way to sophomore year in college n I wore em out! Since then there have been many variations and other companies have made their own versions. Its a good training shoe. Period.
Now this Inneva Woven technology is jus crazy. 12 years in the making, this shoe is built with a very minial base, woven together and laced in a way that its all intergrated. This contours your foot and minimizes waste. To tough! Add that with the Nike Free sole and you have a shoes that out shines the rest. [FM]
