These boots are more rigid than I was expecting, but I had not really owned a rain boot like this before. I wear a size 8, so I ordered a size 8, and they unfortunately came with the foot bed about a size 9. They hugged my calf muscles significantly, and it was hard to get my pants in there. There really wasn't any other tightness problem except for the upper opening. I fixed it by cutting the boot down a few inches from the top. I tried to salvage my purchase...  But after walking in these boots a couple of rainy days, they did hurt my feet enough (because of all the extra movement and the lack of support) that I stopped using them.

Unfortunately this wasn't a winner for me.
