By the original Muck Boot Company. Classic, molded structured, heavy, waterproof "chore" boots. Perfect for barn chores or the like. They are very heavy to wear but solid and dependable. They're a very, very dark green color (in certain lighting almost appears like a lighter black). Womens size 9/9.5 Pre-owned; exterior has staining consistent with boots like this that have been worn a number of times. However, the traction and tread are in very good condition (great tread/not worn). I've cleaned them up as much as possible and now letting them dry by the fireplace. Just inside the boots under the sizing information reads "best to fit with medium to heavy socks," and I can attest to that. Paid $145 when purchased new-asking $50 but OPEN TO OFFERS!!!
