I am a male who wears 9.5 size shoes. I ordered 9 (11 Women's) it fits snug but comfortable. I do not think you would want loose fitting clogs. They are very warm for California winter and comfortable. However as noted elsewhere the liner seems to come off half way when you take them off. I knew about this from other reviewers when I bought it. It is not a big deal; when you want to wear them again you just put the liner back again. I think I rather have removable liner where I can wash them in future than permanent ones. If you want them on permanently I would suppose a shoe repair person might glue them for you. I am very happy about my purchase, I love summer crocks and these are a great winter edition. Looks wise my wife and daughter do not like the looks but I think they are very practical.
