Flyknit uppers will encase each foot in breathable comfort. Perforations
across the forefoot and midfoot increase airflow to create a better, healthier
environment for your feet to thrive in. The one-piece construction seamlessly
integrates these areas of high breathability with stretch and support where you
need it the most, adapting to the changing shape of your foot as it moves
through the gait cycle and reducing slippage so that you can enjoy smooth,
distraction-free strides. Flywire technology woven into the upper merges with
the laces for a dynamic and supportive fit through the midfoot. The strong, yet
feather-light, cables work with the laces to increase support as you tighten
them. Stretch yarns are nestled between
Flywire cables on the lateral side to provide increased stretch in this high
expansion zone, while structured yarns on the medial side supply lightweight
stability; uniting to enhance the snug, contoured fit of the Nike Free RN
Flyknit. Elastic yarns have been added to the heel to supplement the firm and
adaptive feel of the shoe, promoting lockdown and improving stability.
