NATURAL RIDE, AMPLE REFLECTIVITY.
The Nike Free 5.0 Flash Women's Running Shoe offers excellent lightweight cushioning and support while enabling a more natural running experience. A reflective, water-repellent upper keeps you visible, dry and comfortable in dark, dreary conditions.
Hexagonal flex grooves offer six points of flexibility to let your feet move naturally in every direction. Low-profile cushioning and a rounded heel encourage a more natural footstrike.
The three-layer, abrasion-resistant mesh upper repels water while keeping your feet cool. Flywire cables integrated with the laces deliver added support and an adaptive fit.
Inspired by the natural beauty of the Northern Lights, the multicolor reflective upper enhances your visibility in low light.

NIKE FREE 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, similar to 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 running shoe from the inside out.
