I wear mostly Naturalizer shoes due to how comfortable they are so I know how they run.  I purchase these boots for the wide shaft which was awesome but these seemed to get bigger as I was trying them on in my house. The boots are extremely soft so that may be why they were giving in and stretching while I was putting hem on and taking them off while testing them in home on carpet. I would suggest to go down a half size but definitely if you have wide calves like I do, the shaft is perfect. Very cute but had to return them.
