These were only worn indoors a few times and she only wore socks with them. These are super cool style of Birks and super Comfortable. This camera sucks, so if it looks like they have any weird marks on them, pls check another pic to see if it’s still there. I took tons of pics in case of Glares or other anomalies that may not actually be there. lol. Idk why it does that sometimes- making it look like marks are there- which aren’t. 🤷🏻♀️ Don’t miss out on an awesome pair of Birkenstocks!
