I was a footwear designer at Rag and Bone. These sandals are beautiful. The heel is leather and the upper is actually a squishy yet structured neoprene. Stylish and beautiful and tad edgy with the shape of the heel. They are 7.5. Very small wear on the back of one of the heels. It is not very noticeable- the photos bring it out more. This was the first time I noticed. I wore these around the design office at Rag and Bone a few times and that’s it :). They are very comfortable. I am raising money for my healthcare costs. Your purchase supports me seeing a pelvic floor specialist. I am in a lot of pain and your purchase means something to me! I no longer am a footwear designer I work as a teacher and have had to stop working while I recover. Thank you, Caroll Violet lavender purple lilac heels
