Running enthusiasts will not be unfamiliar with the Nike Free Running series on the debut. This running shoe, which was born in 2004, has unique patterns and grooves on the rubber outsole, enabling the feet to flex flexibly when moving in a straight line and in multiple directions, while allowing the toes to move freely, earning the reputation of barefoot running shoes. For example, Nike has now officially introduced the new 2019 Free Running series, and released two new pairs of running shoes: Free RN 5.0 and Free RN Flyknit 3.0. The original design provides runners with an excellent sense of foot. In the series, the flexibility of Free RN 5.0 is 26% higher than that of the previous generation, the sole is 2mm lower, and the sharp silhouette of the shoe body injects new aesthetics into the running shoes; However, the Free RN Flyknit 3.0 is 1mm lower than the 2018 model. At the same time, it uses an integrated shoeless structure, making the Flyknit upper more suitable for the foot. The new 2019 Free Running shoes will be officially launched on March 19, please pay attention to those who like running!
