The Nike Spark Flyknit ‘Burgundy Crush’ (DD1901-600) delivers tones of purple and grey on the experimental model, with a purple rubber midsole that houses ‘Spark’ cushioning, using both firm and soft foam as well as a plastic plate for ultimate comfort. The grey Flyknit textile bootie style upper reveals an inner layer that shows hints of light green and dark red, a red that can also be seen on the laces and sole as well.
