Have bought this deposit for my work shoes because I work in a cold store, the first in the Weeks I was very happy with it but unfortunately they do not keep too long by. After 3 weeks I noticed how they "migrate" to slow heisen they slowly came back to the heel out because the material has become very thin again. Therefore only 4 stars, with less use of them keep you safe longer. But also have to say that it was with the best deposit I had previously was warm give the concerns, no comparison to the cheap things from the supermarket.
