I have finally found the open toe Leather Platform Peep toe (are they Prive?) Louboutins, but they only have a 39.5. I normally wear a 40 in louboutins, but often have a little tiny gap in the back on one of my feet. The 39.5 fit okay on one foot, but one of my long toes comes to the end on the other. There is only 1/8 of an inch difference in sizes, but I don't know if I should go for the 39.5, as I've never had the peep toes and I'm worried that my toes will slide out anyway if I get a bigger size as they are 4.5 inches high and I have a narrow foot that normally sides on open high shoes. Does anyone have any advice?
