According to Associated Press, the retailers pulled the product off their shelves, cut commercial ties with the supplier and forbade their other suppliers from using the sachets.
A statement by Etam said a client developed an allergy after wearing her new boots. A dermatologist she visited blamed the rash on dimethylfumarate. A link between the allergy and the sachets has not been formally established, the statement said. An independent laboratory is currently conducting tests. Etam spokeswoman Florence Troy said one style of boots and a range of high-heeled shoes were withdrawn from 250 stores.
