Based on another review I purchased this boot. I have an ankle injury and it's very difficult to walk for a prolonged period of time without pain. These boots seem to have alleviated that problem. The boots are tight to slip into and a little loose once you actually get your foot in them. This works for me because my foot and ankle start to swell after about a half an hour of being on my feet. I am a size 8 1/2 and size 9 is perfect for me.
