I ordered a 6M in black and they fit a bit tight in width with thin socks on. Although it is snug, it's not too uncomfortable due to its comfy rubber sole and heel. The boots make no noise! One plus is that the top of the boot can be folded down, which converts these to mid calf. The tassel at the back creates a unique casual look and it can be removed if you are not happy with it. The leather is soft and comfy, and it will stretch in time a bit so being a snug fit is not really a big deal. My calves are just over 13inch, and the boots are loose around bare calves as well as ankles, but not overly. With jeans tucked in, it should fit fine. I had no problem zipping up.

Not the most expensive looking boots but the comfortable and casual look is good enough for me, as I intend to use this for travelling and casual everyday life.

For your information, I normally wear 6 Aus / 36 Euro / 6 US / 230-235mm in closed shoes and a half or a full size smaller in sandals. My size being in between sizes, I reluctantly choose snug fit rather than loose.

Oh, the boots were delivered three days earlier than the estimated time. In total, 10 days of delivery time to Australia.

All in all, good boots at a great price. Just go up a half or a full size for thick socks.
For the sale price, I recommend this product.
