These shoes have only been worn once indoors and are very clean, almost like new. I have another pair, and they are slip-in, cushioned, and easy to walk in. Thank you. Phiten Soft Slip-In Sneakers These lightweight and cushioned sneakers use Phiten's unique Metax technology in the insole. While wearing them, they can help relieve muscle stiffness and tension, aid in fatigue recovery and concentration, and are expected to promote beautiful skin penetration and skin tightening effects. Phiten's Metax is a technology unique to Phiten that disperses various metals into water at the nano level using water-soluble metal technology. *Due to specification changes, the insole color may be black or orange depending on the production period.
