The lining is made from soft PET, which comes from recycled post-consumer PET bottles, and the insole is made of recycled PES. These clogs are unisex, ultra-light, and feature a recyclable cork outsole, constructed without irritating seams. They include an ergonomically shaped soft deep footbed, making them ideal for all seasons—even for barefoot wear! The innovative material is almost indistinguishable from genuine leather in terms of texture, appearance, and performance.
