I can't stop being amazed about the number of things out there. There must be a lot of people with a lot of great ideas. I appreciate that very much because it benefits me. Sometimes I look around on Amazon and stumble upon useful things I didn't know existed.
Are you familiar with shoe trays? Those plastic things you put your dirty shoes on? I never really liked them. I think they are too big and difficult to clean unless you take them outside.
On Amazon, I've found some shoe-formed thingies with similar functionality. I have a patio door with a doormat in front, where I have a pair of shoes standing that I use when I go outside to feed the birds. I often drag a lot of empty seed pods in on the doormat with those shoes, which doesn't look good. When I saw these flexible shoe drip mats, I thought that they would do a good job at the patio door. I also hoped that they would be easier to clean. The last thing is still untested, but they do a great job of keeping the empty seed pods away from the doormat.
