For its debut, Nike's Free Powerlines+ II will be offered up in the above Strata Grey colorway. The kicks showcase a perforated side-panel as well as heel, all while sitting atop a speckled midsole. A red heel tab complements the grey spread accordingly, as you'll have to keep it locked to Complex to find out when this Free Powerlines+ II offering will be hitting retail.
