Regarding to the shoes with white default sent back to Taiwan, Yi-Ho sent it to Footwear&Recreation Technology Research Institute(http://www.bestmotion.com/frthome.asp) to test. They examined to see if salt, dried meat or mildew caused this. However,the stuff above were not the reason causing that. They dealt it with show cleanser/cream and the white default gone.
Footwear&Recreation Technology Research Institute assumes that the shoes have been touched by solvent or something and become white powder due to chemical change.
We will asked Yi-Ho to send it to SGS for toxic testing.
亂翻 有人再改一下吧~
