I was searching for a pair of Rain Boots. I looked at many reviews before I chose this pair. When I first tried them on I walked around my house for a bit with them on. I wasn't totally sold on them and they sat in the box for a month before I actually wore them out. The first time I wore them I had my pants tucked in and they were okay. I am a 8/8.5 (depending on the shoe) and ordered a 9 (due to not having 1/2 sizes). I find that my foot slips when I walk and I think because of this I walk heavy in them.
The second time I wore these I did not have my pants tucked and had on a pair of ankle socks. By the time I came home from running errands the back of my calves were red and irritated from the top of the boot rubbing. If I could I would return these boots as I do not want to have to tuck my pants in every time I wear these.
I do want to add my calves are not huge just average size.

UPDATE 10/23: I hate these boots. It has been raining here a lot lately and with the fall weather I wanted to wear these again. What the heck was I thinking. After one day of wearing them I was almost in tears because the top of the boot was rubbing the back of my calf so bad. I even wore socks that came to the top. I honestly hate these boots. But they are waterproof so I guess that is worth two stars.
