They are very light and I don't know how long they will last but so far they are beautiful and in my experience one of a kind. The sole is very non-slip, thin and soft like rubber. It really is like wearing protective socks without shoes. I've worn them in the garden and walked a few kilometers on the city sidewalks and enjoyed the barefoot feeling. The first pair were a bit small but I kept them and ordered a size up which was perfect.
