Incorporating a synthetic wool mixed into the Nike Flyknit thread for warmth, the Nike Flyknit Trainer Chukka FSB features a rugged Nike Free-inspired outsole, originally found on the Nike Special Field Boot (SFB), for all-terrain traction. A synthetic wool lining adds insulation and a reflective skin offers water resistance and improved visibility. Patriotic “USA” detailing can be found on the sock liner and tongue. Releasing February 7 on Nike.com.
