I wore these for a few hours at a family wedding. They're clean as I wore them carefully. I usually wear shoes in the 23.5-24.0 cm range, and these were a little tight. I don't have any pets or smoke! Instant purchase OK, first come, first served. *Please note that these are used items and have been stored in a regular household.
