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



We looked at classic slip-on, open-back clogs and re-worked them to make them feel even better. The KO-Z MULE features supple soft premium combination of Twinface Sheepskin and suede leather with a stretch panel for ease of entry and foothold secured with wooden toggles. 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, the KO-Z MULE stays with your foot with every step. The ultralight sponge rubber outsole brings durability and grip so you can wear these wherever your day takes you – be it indoors or outside.

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.
