Below the faux-fur-covered silhouette sits an EVA foam, retaining the standard construction we’ve seen in all the Nike Calm models. This foam, as well as the faux fur, comes in a tonal sanddrift hue, while the midfoot of the upper contains a small suede Swoosh in a similar shade. For the strap on the heel, we see a felt, suede finish for the Velcro portion and leather-reinforced faux fur for the strap itself. Inside, the footbed and lining of the mule also take on a sanddrift faux fur for warmth and comfort. Rounding out the look is the rubber outsole derived from the Air Force 1 Flyknit, coated in more tonal hues of sanddrift.
