These looks really nice on my stairway! They stay pretty securely without any adhesive, so  I haven't put any tape or anything on the back of the treads yet, but may do so if they start to slip or move around the stairs. Before I put them on, our dog would not go up our hardwood stairs, but with these, he can easily go up and down, which is the main reason we got these in the first place.  These were a great purchase, and I would definitely recommend them!!
