I wore these last winter, and I wore sneakers more often, so although they're clean, the fluffy lining inside shows some wear! There are no noticeable stains, so I think they can still be worn ( ¨̮ ) Please refrain from purchasing if you are concerned, as these have been stored by a non-professional and used by a child(´・ω・｀) I will ship them slightly compressed, so I'm offering them at a low price!
