I wore these in rotation with other sneakers. Overall, I think they're still in good condition, so I hope you can use them as a spare pair. There are some stains that couldn't be completely removed, but they have been cleaned thoroughly. The insoles have become whitish, but it's not noticeable when they're in the shoes. There is some slight wear on the fabric around the opening. The soles have also been cleaned, but the brown color couldn't be removed. I will pack them as compactly as possible. Please note that they may be slightly compressed.
