About this product
Mesh gives the Nike Initiator a lightweight upper with an open texture. White and blue set the colour combination, while the textile lining adds another material detail. Made for women, this version pairs its understated two-tone palette with a plastic sole. The Initiator name brings a clear identity to the design, while the simple colours keep the overall look uncomplicated.
