The inside is lined with a similar material to what they use for their headphone earcups. Pretty straight forward thin script. Really nice set. However besides the size issue these are still great sandals but just very disappointed especially when paying that kind of money. From Italy. Great colour and super comfortable. Thank You for a great product and awesome service. She has unicorn slippers so she can be cool like my granddaughter. This is so light weight I dont even know its there. This is my second pair of Tevas and I highly recommend them to anyone.
