Nike Free Run+ 3 - Men's View All ColorsThe Nike Free Run+ 3 Men's Running Shoe offers a barefoot-like ride with the cushioning, traction and underfoot protection of a traditional shoe. Its low-profile midsole doubles as an outsole, dramatically reducing overall weight.
Fit:The Nike Free Run+ 3 features the Dynamic Fit system, made up of 'fingers' of soft material that wrap the midfoot and arch for a glove-like fit. They move with the foot as you run, reducing the space between the foot and shoe for unparalleled comfort. A stretchy mesh inner sleeve with seamless overlays delivers a supportive, skin-like fit and the minimalistic, molded sockliner mimics the foot's curvature for added support and comfort.
Flexibility:Flex grooves along the length and width of the outsole enhance flexibility and help maintain stability. For added flexibility and to help increase foot strength, the Nike Free Run+ 3 also has diagonal cuts through the arch area.
Origins:After 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, just like bare feet. In 2002, they examined a group with pressure-measuring insoles taped to their feet, using high-speed cameras to capture images of each foot in motion.
