The Lux insole is made of a mixture of cork and latex. This natural dual layer insole not only supports, but cork is a naturally antibacterial material, which absorbs sweat and prevents odors, ensuring both hygiene and comfort. The Lux insole is covered with a soft leather hide. A rubber out-sole provides maximum resistance to abrasion.
Note that the Lux insoles need to be broken to become more flexible.
