I absolutely love these heels. However, I actually needed to purchase a shoe stretcher for the toes. I don't have particularly large feet, and the size I bought has always fit with Demonia, but these toes...Unless you tape your small toe or buy a stretcher, they are extremely hard to get into. The back of the shoe will also chafe a bit, but not anymore than any other new heel would.
They're very cute, and once I put the stretcher in, they were pretty comfortable. (Definitely a beauty over pain type situation here)
