The Nike Free RN Flyknit features a revolutionary new outsole pattern that expands multi-directionally so you can move more dynamically and naturally than ever before. Its single-seam upper provides the incredible sock-like fit of Flyknit for total comfort throughout your run. In other words, the Nike Free’s do not just look great, they are great.
The concept of Nike Free was born in 2001, when insights from a legendary coach inspired designers to create footwear that mimicked the feel of barefoot training but incorporated important protection and support. The first expression of this study released in 2004 via a shoe with a siped outsole (deeply cut grooves that allow the sole to flex freely and translate a barefoot-like feel to all surfaces). Twelve years later, the Nike Free RN Motion Flyknit takes that original technology even further.
Drawing upon new studies that reveal how the foot expands and contracts upon impact with, and liftoff from, the ground, Nike designers developed an auxetic, or splaying, midsole. Spreading across two planes, the geometric tri-star form mimics how the body and foot react to force and accounts for the massive changes in foot size — approximately one size in length and two sizes in width — that occur throughout a runner’s stride.
To form the new tooling, the designers employed a new dual-injection technology. Using heat, instead of glue, they fused two foams into one piece that still features an IU foam carrier and soft IP core but introduces even more cushioning than past Nike Free models.
The Nike Free Run Distance continues the Nike Free principle of providing extremely flexible and very light shoes for the ultimate in natural running.
The lightweight Lunarlon cushioning system delivers miles of soft responsiveness. It fuses soft foam and a lightweight Phylon carrier to deliver an excellent blend of plush comfort and durable support to go the distance.
Single-layer, engineered knit helps keep your feet cool, while Flywire cables integrated with the laces wrap your arch for an adaptive, supportive fit.
