These are pretty amazing. I am still in the process of growing grass so when it rains my yard tends to get really muddy. I have the red clay mud so it's definitely not easy to hide or clean off my shoes. When I leave my house I usually wear a pair of crappy shoes then change into my good shoes when I get into the car. It was such a pain but now that i have these shoe covers i no longer have to worry about that! They are made of high quality materials, strong vinyl. I haven't had any issues using them thus far. They are so easy to put on. Slide them on, zip them up, and you're good to go. They are super easy to clean as well. If they get muddy, a quick rinse is all that is needed to get them clean again. I wear a women's size 8 and got the medium and they fit perfectly. Overall, I am super pleased with these. They far exceeded my expectations. Would definitely recommend!
