I ordered these for my fiance, who has larger, athletic legs. The calf area of the boots was too small to zip up properly. Other than that fit issue, these are very nice boots. As other reviewers have said, they are VERY slick on the bottom, but some gripper pads placed on the soles (found at shoe stores and probably on-line, too) would fix that right up. I was pretty disappointed that they didn't fit well.
