Soooooo comfy!!! I bought these for my 90 year old mum but they are too slippery for her safety on the floor. Perfectly fine for anyone with good balance, I’m sure. I would have kept them, but they’re too big. They do have flower shaped and designer name skid proofs on the bottom of each slipper. The insides are lined with fleece. These are gently worn and the INSIDE HEELS have a wee bit of ware but not bad. There are some teeny pieces of leaf towards the bottom on the backs. However, I have taken photos of the backs for u to look at. Perfie for cold 🥶 weather coming up. Enjoy!!!
