I was looking for an inexpensive pair of rain boots recently due to the fact that I ride a bus to and from work every day. On cold, wet days no one likes to stand outside with wet feet... and then go sit in the office with cold wet feet. That kind of thing can ruin your day.
I was extremely surprised and delighted to get this pair for Christmas, and after trying them on I am even more delighted. The rubber is thick and appears to be durable, though obviously only time will tell if the durability assessment is true. They look great on and are wide enough to accommodate my pant legs so that the legs don't get wet either. I actually have to pull them all the way closed even with my pant legs inside due to having slender calves. I point this out because they have a good three to four inches of room left when fully expanded and could accommodate a large range of calf sizes.
As far as sole/shoe size goes, they run a little large, which is due in part to the width. My nines fit just about the same way my 9.5 running shoes do, lengthwise. But,they are definitely wide. I didn't send them back because well, most rain boots I have tried are wide and what are you going to do if you have narrow feet? I wore thick socks with them and that seemed to do the trick.
Over all, they are great. Comfortable, flexible and dry if you can handle the extra width or happen to need the extra width. I've only worn them once though. Will update with any changes after they've gotten more wear.
