neue diffusion sandals 23.5cm Heel: 6.5cm There is a glue-like stain on the left toe area (Image 7). There is a similar stain on the left inner side (Image 8). Neither are sticky. I received these as a gift, but I haven't had a chance to wear them. I hope someone will find them useful. Please forgive any oversights as these are not new. There is no original box. I will ship them in a box I have on hand.
