Nike Sportswear has just launched two new colorways of their SFB (Special Forces Boot) only this new style features a zippered lace up to give the SFB a more street-friendly aesthetic all while keeping the performance aspects of the boot in tact. The design of the boot remains uncompromised and provides those who wear it more convenience when wore since the zipper allows the shoe to be easier to put on and take off. The SFB Zip is a Nike Tier Zero release and is available in Olive or Kevlar Black colorways.
