NIKE has taken their iconic military boot, the SFB Field, and perfected it. What was there to improve? Look to the details. NIKE did, turning feedback from the field into engineering bullseyes for this addition to the legacy. The upper has been redesigned and reconstructed, now stitched meticulously with leather for durability and quick-drying ventilation. A midsole made of articulated phylon, an innovative lace-locking system, and a complex outsole keep the SFB Field 2 in a league of its own.
