Queen sized friendly! These boots fit calf sizes up to 18 inches, but no further. Zero stretch and no size zippers, pull on style. EXTRA comfortable, no high heel, flat sole, stable base. For reference, I bought size 11 in Banana, size 3xl in clothes. These boots will be perfect for me with dresses and leggings, but I wouldn't be able to get a pair of skinny jeans inside the boots. I got these to wear with skirts and dresses. Perfect for $30. Most boots are $100 and up for the exact same quality. You won't regret these super comfy boots.
