Aerosoles are known for their comfort, and these boots are no exception.  I ordered a size 7 1/2 and, although a little long, I wear them with footwear such as socks and sweater tights, and the fit is perfect.  If you live in a colder climate as I do, I would suggest ordering your usual size and, with footwear such as socks, you'll have no problem.  I have a fairly narrow foot and, again, with socks etc, the fit is perfect.  They have plenty of arch support and are extremely comfortable; you'll still have a spring in your step at the end of the day!  As with any suede product being exposed to inclement weather, I would suggest spraying them liberally with suede protector prior to wearing them.  This is particularly important in a northern winter climate with snow and slush.  These boots look great with jeans, tights, leggings, jeggings, skirts and khakis, so are obviously very versatile.  Beauty in their simplicity.
