The Free sole’s tri-star flex-grooves allow the sole to expand in multiple directions — up to one size in length and two in width — mimicking the expansion of the foot as it hits the ground. Based on the latest body-mapping and physiological science, the new technology produces Free’s most natural motion to date.
A light yet supportive Flyknit upper is built atop that sole, actually stretching under the foot to replace the standard midsole-outsole connection, symbiotically working with that Free sole in the process. I say again: most natural motion to date.
