The white indoor shoes were used for 3 months, and the yellow indoor shoes were used for about 6 months as gym shoes. The heels are slightly yellowed. They have been home-cleaned, but there are some stains that couldn't be removed. There are names written on the surface and heels, and the names have been erased with a name pen. They will be shipped via Yu-Packet Post. When dropped off at the post, the heels may be slightly compressed for shipping. Thank you for your understanding.
