I followed the advice of so many reviewers and bought these booties 1/2 size up but it turns out that that was a mistake because my usual size would have been just fine.  Since I can't return them before I leave on a trip abroad, I bought two different kinds of Dr. Scholl soles at CVS and had to put them both in to obtain a semi comfortable fit. The boots are very stiff and hard, so I'm sure I'm going to suffer, especially where they rub in the front of my leg.  Another thing is that they're kind of slick, it's fine outside but as I was trying them on inside after fitting the insoles, I felt very insecure walking on bare floors.  All that said, they're cute boots, and I love the burgundy color that I chose.  So choose your usual size, and maybe your feet are not as delicate as mine are and you'll love them!  I'm just hoping they'll soften up a bit with use.
Edit 2/22/18 I gave them away to the thrift store, they were just too uncomfortable.
