Rothy's The Flat Shoes in Solid Black Size 8 with flaws

Rothy's the Flat ballet slip-on shoes in black. Soft, comfortable insoles offer support with every step - made from recycled plastic bottles. Machine washable. Pre-owned in good condition - have been worn plenty of times, but still a lot of life left! The back "pad" on the heel of one shoe has started to come off, but is still in tact and isn't noticeable while wearing - I’ve circled the flaw in a picture. These also have some white showing at the seams. It seems like the fabric wasn't dyed/colored at those spots. I don't believe it's glue - it's very thin lines in several spots as shown in the pictures. Size 8 Smoke-free pet-friendly closet
