The best way to care for your SoleMate is to ensure your feet are clean before use. If you do notice your SoleMate looking a little dirty just use a sponge or rag and a solution of basic soapy water to gently scrub the cork.  Mold and mildew love wet cork so make sure you remove all the water from after cleaning it. Use a cloth and press on the cork to dry it. Once you’ve pressed out as much water as you can, leave the cork to air dry completely. Do not store the SoleMate until it is completely dry.
