I bought the black and the tan, BOTH in a size 6. I thought the black ones were a little on the small side. I have very small feet, not wide at all. But, after walking around in them, no socks, they didn't feel as small, and it came a day early. Thanks for that too! The tan ones are a different story all together. They are the EXACT SAME SIZE, but for some reason, they fit/feel like a seven! I tried them on barefooted, and with m my thickest pair of socks, and it still didn't work! My heel kept coming up, while the boots clunked around on the floor! Idk if these are new or if someone just returned them after they stretched them out ?♀️ So I had to give them to my 20yr old daughter who wears a size seven, and guess what?! They fit her! ?♀️ Why is there such a BIG DIFFERENCE in the boot's size but are just different colors? I don't have the kind of money to buy another pair, and I am afraid to order the five, and it be too small! Overall, the black and the tan are good boots. I am very happy with the black ones, but very disappointed that the tan ones were too big.
