Mine fit perfectly. I sized to what I typically would size for boots and they fit snug. If you have bigger calves maybe go a size up? They were only really tight in the calf area. Just be careful pulling the zipper up. Super comfy.
Rated 0 on a scale of minus 2 to 2, where minus 2 is Runs Small, 0 is True to Size and 2 is Runs Big
