I have personally tested these boots for over a year. They are easy to walk in, don’t absolutely kill your feet, and hold up VERY well. They are my go to boot! I LOVE them! They have an inside zipper (about 6”) and a 3.25” heel. True to size I am 5’5” for reference. I have sprayed mine with a waterproof spray since they are suede to protect them from New England winters.
