Men's Nike Free 5.0 Flash Running Shoe - Blue/Blue, Blue/Blue

NATURAL FLEXIBILITY, HIGH VISIBILITY The Nike Free 5.0 Flash Running Shoe features a highly flexible, low-profile outsole and lightweight support for natural movement and enhanced cushioning. Reflective details and a DWR (durable, water-repellent) finish lend high visibility and protection against the elements. New hexagonal flex grooves are hot-knife cut into the outsole and wrap around the sidewall, allowing your foot to move more naturally in every direction. The knit mesh upper is reinforced with Flywire on the midfoot for lightweight ventilation and an adaptive, supportive fit that moves with you. The heel mimics the shape of your foot, rolling with the ground to promote a more natural footstrike. With an 8mm difference between heel and forefoot height, the Nike Free 5.0 offers the highest offset of Nike Free running shoes for greater cushioning with the foot-strengthening benefits of natural motion. *No-sew overlays for support and durability without added weight *DWR (durable, water-repellent) finish to help keep out the elements *Reflective upper and midsole for high visibility in low-light conditions *Waffle outsole lugs help absorb impact and add responsiveness *Minimal sockliner molds to your foot's curvature for added support and comfort *Weight: 252 grams (men's size 9) 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. Since Nike Free's introduction, millions of runners have trained in the shoe, including some of Kenya's world-class runners. Click the banner to get it at ONLY: GBP29.00
