Sandals reformulated with the street performance of sneakers and comfort of slippers



Inspired by the world’s tallest mountain, the KO-Z EVRST takes new heights to reach the peak of comfort. With plush shearling and looped wool 360 degrees around the foot, the KO-Z EVRST is a slip-on that delivers softness and a sense of well-being. The upper has a notably wide panel of premium Nubuck Leather with 10 mm wool that gently wraps the top of the foot with extra KO-Ziness, thermoregulation and moisture management. Under the foot is 5mm of looped wool layered on top of 5 layers of foam – with the softest memory foam closest to the foot. The memory foam embraces your foot’s shape and gives back a delightful cushion sensation that helps stabilize the foot. With the addition of a rocker in the midfoot and an extended squaretail rear, this KO-Z sandal stays with your foot as you walk or run.

This product was made in a factory that supports women in our supply chain with the help of HERproject, a collaborative initiative that creates partnerships with brands like ours to empower and educate women in the workplace.
