Assuming you have normal human-sized steps, the product photo makes these look like they’re much smaller, so I was pleased with the size. However, they slide around like crazy! The underside is smooth, flat, and glossy and has no grip at all!! I bought them specifically to provide more grip on my steps, so it’s no better functionally than if I were just using the steps bare again. Now I have a pretty annoying little thing to constantly be fixing, just for the small aesthetic boost to my garage. Big whoop.
