Nike has breathed new life into one of its most beloved vintage collections – Nike ACG – by infusing its most modern technologies into both apparel and footwear. On the sneaker front, NikeLab presents the ACG Flyknit Trainer Chukka SFB, which has been updated from the slew of releases over the summer to function at a higher level on the streets. Here we find the shoe engineered with a new protective skin at the toe and heel, then laid over with a Defender Repellent Systems® spray layer for maximum weather resistance. These features are complimented by a synthetic wool yarn lining at the interior of the shoe, which works in conjunction with Nike’s penchant Flyknit technology to conform to (and warm) the foot. Look for this release to drop alongside the rest of the NikeLab ACG collection on December 18 here and at NikeLab locations in New York, London, Tokyo, Paris and Milan.
