The White Walkers are undead creatures from the North that only have one thing on their minds: destruction. As their name suggests, the White Walkers are primarily white or icy blue, owing to their natural, albeit frozen, habitat. Their Ultra Boost is dressed in primarily white Primeknit, with hits of contrasting black on the tongue, liner, and Three Stripe branding. The lace cage, heel cup, and mudguard are a translucent, icy blue, another color seen on some of the White Walkers. The phrase "Winter is here" is present on the heel, which is the biggest giveaway, as the White Walkers come when the winter does. A white Boost midsole and white rubber outsole continue the theme.
