Wear a 6.5 -7 boot. Bought a 7 in these brown boots. Super cute and affordable. All the studs are secured and the zipper works fine. Shaft circumference is adequate for calves and not too bulky or too tight over jeans. I don't wear too much brown but love these boots. Recommend Breckelles in this style and the lace up style. I own 3 different pairs now and they all have held up to the harsh conditions of traveling and shopping all day without needing to change due to blisters or pressure points. Very stylish and my preferred brand for when I dress up a little more and want to stand out. I have purchased 6.5 and 7 and both sizes seem to be about the same. I do wear socks with all my boots. I hope this helps.
