The Nike Flyknit Trainer Chukka FSB was first (very appropriately) introduced during the Sochi Winter Olympics. Essentially a beefed up version of it’s lighter cousin, it features a knit wool-blend upper and Flywire cables for comfort and stability, along with synthetic overlays on the heel and toe to provide extra durability and weather resistance. Today we bring you two new colorways – the “Squadron Blue”, which sits on top of a speckled grey OMS outsole, and the “Charcoal”, made with a light grey upper and black accents. This winterized version of the popular Chukka model is perfect for those of you who want to rock a woven look during the colder months. The Nike Flyknit Trainer Chukka FSB in “Squadron Blue” and “Charcoal” is available now through select Nike Sportswear retailers including Sneaker Politics.
