I've worn these for six months. There's no major damage, but please forgive any oversights. The elastic band has some minor fraying, so you may want to replace it if you're concerned. There are slight stains on the toes, heels, the rubber soles, and the fabric edges. Due to the nature of the product, there is some pilling on the insoles. Returns are not accepted, so please feel free to ask if you have any questions! Thank you for looking. Size: 17cm and up
