All shoes/sandales need to comply with NOM020 requirements.  This information needs to be either stamped or sewn in directly to the item itself.  If the item is sold in a box, this information needs to be added to the outside.  There would be two ways to start a project, login to the website and start a new project, select NOM020 and the questionnaire will request the information we need.  The other option would be to complete this NOM020 worksheet.
