The size isn't specified, but I believe it's a LL size, which is about 24-24.5 cm. I was able to wear them perfectly with a 24.5 cm size. Heel is about 6.5 cm. They have good cushioning and are very comfortable to wear. I've worn them for a long time. There are scratches on the cork part, and some dirt on the soles, so there's some wear and tear, but I think they can still be worn.
