I was looking for treads to minimize the risk of falls on our wood steps as we mostly walk in socks in the home. I wanted something that wouldn't damage stairs with tape residue or require installation and these fit the bill. I was hesitant to order because of the price compared to other products. We have two sets of stairs but I ordered one set to start. They exceeded our expectations. They require zero effort to install and can easily be moved, yet stay in place. I just ordered the second set. Love them!
