To use these shoes, simply open the zipper and lace them up according to your comfort. The removable cork insole can be taken out if you want to replace it with your own orthotics. When walking, enjoy the great grip and shock - absorption of the air cushion sole. For maintenance, clean the leather linings with a soft, damp cloth regularly. Avoid getting the shoes too wet, especially the cork insole, as it may get damaged. Store them in a cool, dry place when not in use to keep their shape and quality.
