Free 5.0 highlights the natural movement of the foot and experiences the perfect barefoot feeling. Nike Free sneakers were first launched in 2005. This lightweight running shoe is designed to strengthen the feet and legs through barefoot training while also providing the protection and traction it deserves. “If you want to experience the benefits of barefoot training, environments such as pure beaches or soft grass are undoubtedly the best choices, but such luxurious conditions are not available to everyone. The advent of Nike Free sneakers gives athletes the opportunity to Experience the benefits of barefoot training first-hand in any environment,” said Tobie Hatfield, Innovation Manager at Nike’s Innovation Kitchen. Innovations in the 2009 model include a special tongue structure, which reduces pressure on the instep and adds support to the foot by wrapping the arch. The innovative design of Nike Free5.0 also includes a man-made fiber patch that fits closely inside the upper. This patch is only affixed in necessary locations through ultrasonic welding technology, creating a seamless environment inside the shoe and making it more comfortable to wear. . The positioning of these medial panels has been carefully designed to achieve a perfect balance between the fit, durability and support of the sneaker and the dynamic elasticity of the foot, thereby maintaining flexibility and lightness when training barefoot. Since the Nike Free sneakers were born four years ago, every design change has been subtle, but they have greatly improved the performance of the sneakers. In the process of continuous improvement of Nike Free, this outsole structure that allows the foot to maintain natural movement has been widely used in high-end functional sports shoes such as basketball shoes, training shoes, tennis shoes and traditional running shoes. “The highlight of Nike Free is that it’s really suitable for anyone,” said Andreas Harlow, global creative director of Nike Running Shoes. “Whether it’s outstanding athletes or ordinary athletes, they often use Nike Free as training equipment. Some of them are professionals. Runners, some are athletes engaged in other sports, or just run for training for their own sports. "The development of Nike Free sports shoes begins with shoe lasts, which are used in shoemaking. Foot model. Traditional shoe lasts are flat models with pointed ends. The shoe last used in Nike Free sneakers is closer to the shape of a barefoot. The way the shoe last is wrapped and the materials used make the entire design feel closer to a barefoot feel. Regarding the evolution of Nike Free, Tobie Hatfield added, "We must maintain a one-to-one correspondence between the upper and the sole, that is, the elasticity of the sole and the support of the upper must be in harmony - the elasticity of the sole must be consistent with The degree of support of the upper should be consistent. There must be no master-slave relationship between the two, otherwise the simulation of barefoot running will be greatly reduced. We have improved the soles of the first two Nike Free sneakers, but until today, the upper The function has been improved accordingly. "According to the sports shoe flexibility score, 0.0 is for barefoot running and 10.0 is for standard running shoes (such as Nike Zoom Vomero). Nike Free5.0 is about in the middle, and Nike also launched Nike Free3.0 and Nike FreeEveryday, which is between Nike Free 5.0 and standard running shoes with 10.0 points. The new Nike Free 5.0's specially designed upper has sufficient support while keeping the foot natural and dynamic, imitating the movement of bare feet. A breathable mesh covering most of the upper enhances breathability and comfort, while also providing a comfortable, barefoot-like fit. The placement of the panels has been carefully designed to provide the perfect balance between fit, firmness and support with dynamic flexibility in the foot. “You can call Free 5.0’s design ‘process creates beauty’, we always strive for excellence in external design.

"Andreas Harlow said, "The more faithful you are to the goals and processes you set during the work process, the more perfect and eye-catching the results will be. "The phylite midsole of Nike Free 5.0 uses a "waffle" outsole structure to achieve a lightweight and elastic cushioning effect. It also enhances the sensitivity and grip performance of the sneakers, making the sneakers more durable. Medium The wear resistance of the sole can reach twice that of the outsole, which greatly reduces the overall shoe weight. The deep pattern designs around the midsole of the men's and women's Nike Free are different, and these designs can provide flexibility during barefoot exercise. and stability, while retaining the traction performance of sports shoes, as well as the protection and cushioning performance of the soles of the feet. The "waffle" outsole allows the energy to be transferred appropriately and effectively during each step off the ground. Designed with wider grooves to enhance the propulsion force of the toe, while improving muscle movement and a more perfect barefoot feel, the molded insole inside the sneaker perfectly simulates the foot curve to achieve an unparalleled fit. It also greatly enhances comfort and support. The forefoot and heel are equipped with soft and strong foam lining, which provides excellent cushioning effect to necessary parts. The Breeze series is a kind of clothing that makes people feel cool. Series, the logo is the word CLIMACOOL! ! The Breeze series provides ventilation and humidity adjustment.
