What a great value! I use these for garden boots and they are everything I need, water and mud-proof. I am 8.5-9 and 9 fits perfectly, snug with thick, polar socks. On colder days they do need appropriate socks because they're not well insulated. They are adjustable, but only go wider from how they were set when they arrived. Though I am slim (110lb, about 5'5"), I do not need to adjust them in any way. I was considering Hunters forever.. I'm really glad I came to my senses and got these instead.
