I wear a size 12 shoe. Summary:As mentioned, tested with others. Is ok, just ok +++Trotz der oben genannten Probleme,gibt es von mir keinen Punkabzug. Amazon at the very bottom of each shoe shows additional fit information. There is something a bit intoxicating about the C10 when compared. I can watch this film again and again Sigh. Participants on conference calls told me that i sound clear with crisp audio in Zoom calls. this product reviewed here is great.
