Nike Free footwear lets feet flex, splay and move the way they want. Built on a more anatomically shaped last than traditional running models, the 2019 Nike Free Running Collection introduces new elements that enable a more barefoot-like feel than previous versions.
Because Nike Free is intended for lower-mileage runs, the foam cushioning in the new Nike Free midsoles is firmer (closer to that of the original 2004 model to promote a more barefoot-like feel underfoot), flatter and lower to the ground, delivering greater connection and more natural range of motion than before. The midsole now features siping along the top and bottom to increase dorsi and plantar flexion. Based on data mapping, varying depths in the sipes are placed where the foot naturally wants to bend and stretch to enhance the feeling of movement and to allow for more natural foot motion.
The Nike Free RN 5.0 (shown first) is 26-percent more flexible and 2mm lower to the ground while the Nike Free RN Flyknit 3.0 (shown second) is 1mm lower to the ground than the 2018 models.
The minimal uppers, a thin-stretch mesh with a minimal lacing system for the 5.0 and a lace-less Nike Flyknit with a secondary lock-down overlay for the 3.0, were designed to enhance the natural, second skin aspect of the shoes. There’s a nod to the in-depth science behind the original shoes in overall aesthetic too, with some of the design lines come from the natural shape of the foot, for example). The smaller Swoosh symbolizes the shoe’s lower-mileage intent.
The 2019 Nike Free Collection will be available beginning from March 25.
