Only tried on indoors after purchase. (I bought them on a whim, but they were a bit too flashy for a man in his late 40s...) For reference, the seller usually wears size 8.5 (27cm) in Keen, Adidas, and Converse sneakers, and size 8.5-9 (27.5cm) in Nike. Since they were only tried on once, I think they are relatively clean, but they are used items that have been in someone's hands. Please judge the condition from the photos. Please note that they will be shipped in simple packaging. Thank you for your understanding. Thank you for your consideration.
