Nike Free RN Flyknit 3.0 Women's Running Shoe SLIP IN AND STRETCH. Never worry about laces in the Nike Free RN Flyknit 3.0. This remix leaves them out – letting you slip in quick and hit your stride even faster. Supportive yarns join stretchy Flyknit for a lightweight upper that feels like a second skin. Heel-to-toe grooves in outsole move and bend with every stride.

A strap across the midfoot provides stretch and structure. Anatomical outsole follows the shape of your foot for cushioned response. Single-density midsole foam fits closely to your foot. Sockliner gives your foot a more connected feeling to the ground..
