I am only writing a review based on my initial information of these shoes. Like an idiot, I read the reviews and made my decision of sizing based on several reviewers who said to size up. Um, not so in my case. As with most dancing shoes, it is tricky to find the right size. I do tend to read reviews of other dancers and figure out what I need to do for the best shoe fit. I have had to return these shoes and am now sizing down one full size. I ordered an 8, which is a half size bigger than my normal street shoe, and these were absolutely way too big. These shoes, because they lack a normal arch, and have stretch in the arch as well so that you can maintain pretty, pointed toes, have a lot of give to them anyway. Sizing up in these shoes made me feel as if they were going to fall off in an instant while glissanding and doing pirouettes across the floor. Dancers can not have this and this could be a potential to hurt oneself if they are bracing themselves because their shoe is about to fall off! For those looking into this shoe, you might want to just stick with your normal street size. I like my shoes a bit on the snug side, since I do tend to use them quite often and also sweat in them so they tend to relax and stretch. I am getting a size smaller than my normal shoe size, because I do like them snug. Will update when I get the right size!
