these boots are wide calf friendly I have a 18inch calf they were loose around my calfs however I did size up one size I should have got my regular size no need to size up!!! theses are pull on no zipper easy to pull on didnt struggle much they were very comfortable to walk in not tight around my foot with a kitten heel you can literally walk in these all day. I got both colors I wish they were more!!! I definitely recommend these to anyone who’s not a heel girlie and still want to walk around cute heel boots!!!
