Unfortunately they do not fit larger feet. I wear a women's size 10 and that makes them just comfy, but when my son comes home from college at his height 11 1/2 feet they will definitely rip! My friend who wears a size 12 came to visit and decided to just take his shoes off. So for me it's wasted money. My mom and I will use them, but the search continues for those that are for anyone who comes to visit or when my son forgets something in his room after he's already put his shoes on, which often happens.
