Hi Jos, we are very sorry for the odor issue you encountered while wearing our nylon leggings. Synthetic fibers such as nylon may have a slight odor residue during production and storage, which is usually harmless to the human body, it is recommended to hang the socks in a well ventilated area for 2-3 days, or soak them in water for cleaning. This odor will naturally dissipate. ‌

Thank you for your feedback, your satisfaction is our aim:)
