The frog isn't as adorable as some of the other animal boot and shoe scrapers, but he may be more practical. He has 4 rubber nubs under him, to help keep him from slipping around while you use him. He is also wide and low to the ground, so he doesn't tip over. He is perfect as an occasional shoe scraper that you have out for looks. (If you need a heavy duty boot scraper, I wouldn't get the type shaped like an animal.) We keep him on a stone step outside of a cabin to greet guests and provide light shoe scraping.
These are very "cushy" for feet especially in the kitchen or work area. Additionally, they don't look "industrial" [like tire treads}. An added plus is they can be swept off or taken outside and hosed down. Have them everywhere in the house!
