I bought these on amazon in 2013 as my first pair of lolita shoes. They are a womens US 8.5 and I feel they are true to size because the toe area is rounded so your toes aren't squished. They are very comfortable & easy to walk in, but do have some damage. I haven't worn these in years and they need to go! Unfortunately I cannot pull up the amazon listing for them as they don't exist, there is a 39 written on the bottom of the shoes so I figured that had something to do with sizing. I also can't find these anywhere online, probably because they're so old. 

Amazon listing had these as a 75mm "Heel Knee-High Round-Toe Lolita Boots"
