Kate Spade Mandy bow charm flip flops with black floral pattern size 11

Kate Spade Mandy flip flops. Black and white floral pattern with small black plastic straps tied in a bow at the front of the shoe. A small gold tone spade charm hangs from the bow. The shoes are in great shape. Almost new however where the sticker was on the footbed is darkened. I attempted to clean is leaving a whitish streak. The toe on this same shoe shows a darkened spot. The bottoms are in almost pristine condition. I am a size 9.5 and these are too big. Based on the measurements of the sole being approximately 11" they are a size size 11 - 12. Perfect with a cute dress, shorts or romper.
