The Nike Calm in Fir/Gum Medium Brown/Fir has a dark green body above a warm brown sole. A small tonal Swoosh sits on the outer side, while the opposite side has a triangular cutout behind the covered toe. The rear remains open beneath an adjustable green strap. Fine texture covers the molded upper, and wide diagonal channels run across the gum-colored underside.
Nike forms the contoured body from a single piece of water-friendly foam and adds a textured footbed. The heel strap can be adjusted or removed, allowing two different ways to wear the same mule. A rubber outsole supplies the ground-contact layer, with the side opening providing ventilation through the enclosed design. The low rear platform and broad front make the shape distinct from an open-toe slide. The Fir mule appeared at a regular US price of $65 on Nike’s September 22, 2026 product page.
