Nike Free 4.0 Women's Running Shoes - Strata Grey, 5
Nike Free 4.0 Women's Running Shoes - Strata Grey, 5 EXTREMELY FLEXIBLE AND LIGHTWEIGHTThe Nike Free 4. 0 Women's Running Shoe is more flexible than the Nike Free Run+ 3 and more supportive than the Nike Free 3. 0. Like those styles, it combines the feel of barefoot running with cushioning, traction and underfoot protection. Unique LacingThe asymmetrical lacing system reduces pressure for enhanced comfort. Seamless UpperThe seamless upper offers lightweight support where you need it. It features a laser-perforated design for a supportive, skin-like fit that moves with each stride. FlexibilityDeep flex grooves along the length and width of the outsole enhance flexibility and help maintain stability for a more natural stride. To dramatically reduce the shoe's overall weight, the low-profile midsole doubles as an outsole. Supportive FitA stretchy mesh inner sleeve delivers a sock-like fit that hugs the foot, yet still allows for easy on and off. The minimalistic, molded sockliner mimics the curves of the foot, delivering support and a great fit. OriginsAfter 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, simulating bare feet. In 2002, they examined a group of men and women with pressure-measuring insoles taped to their feet, using high-speed cameras to capture images of each foot in motion. The team spent eight years studying the biomechanics of shoeless running. The results yielded a profound understanding of the foot's natural landing angle, pressure and toe position, allowing Nike designers to build an unconventional and flexible running shoe from the inside out.
