The Women's Free TR 5 Flyknit Training Shoe from Nike ups the ante with a new, lightweight Flyknit upper that adapts to the shape of your foot, offering a locked-down feel for cardio, strength training and other gym workouts that demand flexibility and support. The hexagonal flex grooves are hot-knife cut into the midsole to create six different flex points that allow your foot to move more naturally than ever before. Its molded foam lines the heel collar for a comfortable fit that helps lock your heel in place, and Flywire cables integrate with the laces to help stabilize your foot during agility training and cardio classes.
Flywire helps provide ultra-lightweight support and comfort for your foot. It gets its strength from thin Nylon fibers strategically placed on the upper of the shoe to hold the foot in place, helping to reduce slippage during activity. This allows for a massive reduction in weight because material is used only where it s needed for structure.
Natural and synthetic durable outsole for improved traction and wear over time.
An innovative upper material, constructed entirely of tightly woven polyester yarn that varies in density: more open in targeted areas that need greater flexibility or ventilation and tighter in areas that demand support. Precise knit construction process integrates stretch and support for a more exact fit.
A lightweight form of rubber or plastic made by solidifying liquid foam
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 and flexible running shoe from the inside out.
