I decided to try no tie shoe laces for my son. I saw these and decided to try them. They are made of a stretchy rubber-type material. I thought that they were a stretchy fabric (no I did not read the description) They have anchors on each end to keep them in place, which I think is awesome! They are a little difficult to get through the holes of the shoe, but they work great. All in all these do work very well!
