Manufacturers and importers of certain general use products (i.e., non-children’s products) for which consumer product safety rules apply, must certify, in a written General Certificate of Conformity (GCC) based on testing or a reasonable testing program, that their products comply with those applicable rules. All of our domestic footwear is made using the same process, from the same material,purchased from the same supplier. Unless a formula, or supplier change is made, we follow the recommended guideline of annual testing using the most stringent testing protocols as required by our major customers.
