I got these in the turquoise flower print and I LOVE them!  I wear a 7M in shoes/heels and always order a 7.5M in boots.  I got the 7.5M in these and they fit perfectly!  As the other reviews said, there isn't much in the way of padding but there is plenty of room for an insert if you need it.  I am substantially over-weight and I do not need the extra padding because they are well made and comfy.  As long as you aren't one of those people who think their shoe size is smaller than it actually is, you will be good with your normal BOOT size - which is always a 1/2 size larger then your SHOE size.
The material on this one is great - very cute and bright colors and it looks well made as far as the seams and such too.  They are very adjustable with the ties and they are cut both up all the way and also folded down.  I have fairly narrow feet and these still look slimming on - great looking boots!  I am very happy with my purchase of these fabulous, adorable boots - GO BETSEY!!

****UPDATE: I also ordered them in the Taupe color.  I returned those!  The color is different than the picture and its not taupe, more of an ugly brown color.  I can't explain properly but the brown isn't a regular brown or tan, its just a really odd and ugly color.  Also, the print part of it is shiny and plastic looking - very unattractive!  **I still love my turquoise ones though!
