"So I read a lot of reviews before buying these. I am a 7.5 and bought a 7. They fit perfectly. The calf is loose enough for me. It's not to tight like most reviews say. I am 5'8 130 pounds if that helps some of you out there. I wasn't expecting them to be lined so nicely on the inside. For a rain boot and only paying $50, you can't go wrong. I recommend these."
